Über eine Schwachstelle im Network Time Protocol (NTP) des VMware ESXi Server können Angreifer beliebigen Schadcode einspeisen. Ein Patch ist verfübar.

Laut einem Bericht der Sicherheitsexperten von Secunia betrifft die Schwachstelle alle aktuellen Releases des VMware ESXi Server in den Versionen 3.x und 4.x. Die Sicherheitslücke entsteht durch den Einsatz einer anfälligen Version des Network Time Protocol Daemon (NTPD) in ESXi. Diese weist einen Begrenzungsfehler in der Funktion „crypto_recv()“ auf über den sich ein Stack-basierter Pufferüberlauf auslösen lässt. VMware bietet seinen Kunden ab sofort einen Patch an, der die hochkritische Sicherheitslücke schließt.

Top 5 Planet V12n blog posts week 47

It was very tough to pick a top 5 this time as most posts this week were about vSphere Update 1 and View 4. But I did manage to find 5 excellent articles again. Make sure you read them:

  • Scott Sauer – More Bang for Your Buck with PVSCSI (Part 1)
    So let’s first find out if it’s all that.  We need to do some testing
    to validate the hype.  I created two virtual machines, one with the
    traditional LSI Logic SCSI driver, and one with the new PVSCSI driver. 
    The host is the same for each VM, 4 socket Intel Xeon system with 64 GB
    of RAM, connected to EMC Clariion CX3-80 storage.  The Raid
    configuration is a 4+1 RAID 5 set (10K spindles), with the default
    Clariion Active/Passive MRU setup (No PPVE).  Each VM has 2 vCPU’s and
    4 GB of RAM and both are running 32 bit Microsoft Windows 2003 R2. 
    Both Virtual Machines data disks were formatted using diskpart and the
    tracks were correctly aligned.  Anti-virus real time scanning was
    disabled on both systems.  This test is meant to get as close as
    possible to a standard configuration that we can benchmark from.
  • Arnim van Lieshout – Geographically dispersed cluster design
    Let’s take it back one step and have a look at an active-passive setup.
    These setups have some sort of storage replication in place. The most
    common design I encounter is showed in figure 1. In the main datacenter
    there’s an ESX cluster with some sort of SAN based
    replication/mirroring to a second datacenter. In the second datacenter
    there is a passive ESX cluster available to start-up the virtual
    servers in case of disaster. Let’s use this setup as a starting point
    and turn this active-passive into an active-active setup.
  • Andre Leibovici – Your Organization’s Desktop Virtualization Project – Part 3
    At the time this solution was designed, the numbers of users per CPU
    core could range from 3.8 to 4.2, however for most VDI deployments
    using new processors (Intel Nehalem 5500 and AMD Phenom II) this number
    can be around 6.0 per CPU core, allowing up to 100 virtual desktop
    machines in a single dual-quad server.
  • Scott Drummonds – Another Day, Another Misconfigured Storage
    You will have to size your storage to peak, to average, or somewhere in between. If you size to the average, you are counting on the peaks occurring at different times. If you are wrong, when two workloads peak simultaneously, a bottleneck will form at the array. Also note that sizing to the average in this case (350 IOPS) is insufficient for VM C’s peak of 400 IOPS. You could size to the aggregate peak of 1200 IOPS but unless all of the virtual machines peaked at once the workloads would never consume the available bandwidth.

    All you can do in this case is make a best guess and modify later, as needed. I often suggest that a good start is one third of the way from average to peak which equals 633 IOPS in this case. If we assume 150 IOPS per spindle, that means five spindles for this VMFS volume.

  • Luc Dekens – Scripts for Yellow Bricks’ advise: Thin Provisioning alarm & eagerZeroedThick
    This script will convert an existing thick VMDK to eagerZeroedThick. As you can read in Duncan’s blog entry there is a serious performance improvement to be obtained by doing this.

    Note that the guest needs to be powered off to be able to do the conversion ! This is in fact the case for most of the VirtualDiskManager methods. See also my Thick to Thin with PowerCLI and the SDK entry.

Energize and Save – Standing Out in a Crowd

VMware_Rick Jackson_2009_crop

Posted by Rick Jackson
Chief Marketing Officer

When a company grows as rapidly as VMware has, you know there is real value being delivered to customers.  One of the challenges we faced at VMware was how best to articulate our core value proposition, when there were just so many great things to talk about.  This was a classic exercise in defining the Point That Matters, the core reason why your customers buy from you.  (The Point That Matters is a phrase I borrow from Zoom Marketing, our trusted partner during this process.)

This exercise was a combination of examining our own internal view of our value proposition, compared to an external view shared by our customers, partners, and industry analysts, all of which were quite familiar with VMware and its solutions.  Through this exercise, we heard some not so surprising things, but with a few twists that really made us think about our positioning. 

For example, most people immediately think of cost savings as the primary benefit of virtualization.  While cost savings is definitely a factor in driving organizations to initiate a virtualization journey, it was not the pinnacle of value that was obtained.  In fact, those customers that had pursued more aggressive virtualization adoption were most excited by the achievement of flexibility within their IT environments, leading to significantly reduced management time, and dramatic improvements in their responsiveness to business.  In short, they were achieving IT agility, and in turn helping fuel business agility. 

When asked to rank statements related to our value proposition, both customers and prospects believed that the core value proposition was around the duality of achieving a dynamic, and flexible IT environment, while at the same time reducing costs.  This was something they believed to be unique to VMware.  Most importantly, they believed that this was the correct order as well – flexibility over cost savings.  Frankly, we knew this was a benefit, but have traditionally always led with our cost savings message. 

The other important thing we heard is how achieving flexibility and agility within IT really does put IT in a position to better serve the business – to respond to change and opportunity that can fuel growth.  In essence, they were better positioned to be a strategic partner to the business. 

The problem now was how to articulate a core set of messages around this point that matters, that doesn’t sound like every other IT vendor.  Take a quick browse around some websites, and you’ll find a common theme – everyone seems to promise dynamic, flexible, adaptive, on-demand, solutions for IT.  Hmmm. 

One of the things that stood out to Zoom Marketing during this process was how energetic VMware’s employees, customers and partners were.  During interviews that should typically last 30 minutes, our ecosystem wanted to keep on talking, typically an hour or more.  There was true excitement about the value they were seeing, and in the promise of VMware’s vision for bridging existing IT environments into the era of cloud computing.  This gave us an idea, a way to encapsulate the value proposition of our solutions, with the value that an agile IT environment provides to the business:

Energize the business through IT, while saving energy – financial, human and the earth’s.

The whole point of IT is to fuel the business.  So the whole point of achieving a more dynamic and flexible IT infrastructure is to be more adept at fueling that business, or as we like to say, energizing the business.  But the duality of our core value proposition cannot be ignored.  Our customers talk about real savings, in 3 categories:

  • Optimizing Financial Energy – doing more with less.  Significant capex savings. Greater efficiencies in server, storage and networking. Saving financial resources to apply to the needs of the business.

  • Shifting Human Energy – shift from serving hardware, to serving the business.  Dramatic reduction in manual tasks, and management time.  Simplified operations, supplemented with automation.

  • Saving Earth’s Energy – using less, and using it more wisely.  Doing their part to reduce energy consumption and their respective carbon footprint.

The words are ours, the sentiment belongs to our customers.  What a great opportunity to learn from them, and be in a position to echo their sentiment.

Top 5 Planet V12n blog posts week 45

It was an exciting week this week. For some the VCE announcement was not a real surprise for many it seemed to be. Like always some were skeptical and others were enthusiastic about this new initiative. The first post on this Top 5 covers every single aspect, keep in mind that Chad is an EMC employee. I can also recommend the articles by Chuck Hollis on this topic but as he is not part of PlanetV12n he did not make the top 5:

  • Chad Sakac – VCE Coverage: Post 1, Post 2, Post 3, Post 4, Post 5, Post 6
    Let’s focus on the “Vblock” management layer. To restate the challenge – the goal is to have a thing that makes utility-like management of a Vblock (or more importantly a series of them), including server + LAN/SAN network (UCS manager does this well for one UCS system) + storage itself. As with all things in the VMware, Cisco, EMC consortium, we know customers need choice – and any one element is replaceable. The value proposition is that the things we build are so tightly focused, so tightly integrated, that if you are looking at something like this – the integration value is so high it’s nearly irresistible.
  • Alan Renouf – Virtu-Al VESI & PowerGUI PowerPack & vCheck v3
    I have been teasing people on twitter for a week or so now and have
    just uploaded my PowerPack to the PowerGUI site, you can download it
    here. This is a first attempt at providing most of my scripts in one
    PowerPack and adding to the already great management that VESI and
    PowerGUI give you.
  • Andre Leibovic – Your Organization’s Desktop Virtualization Project – Part 1 & Part 2
    I would anticipate that when your CAPEX is calculated for the next 5
    years after the adoption of desktop virtualization your CIO and CEO
    will not be very impressed only with the numbers, especially if you
    have incorporated acquisition of Thin Clients to your CAPEX. If you are looking for a justification to adopt desktop
    virtualization you should focus on your OPEX and cost savings coming
    from Lower Operating Cost/TCO, Power and Cooling Energy Savings and
    increased seat utilization, when applicable.
  • Mike Laverick – Virtual Compute Environment – VMware, Cisco and EMC Coalition
    So here’s my attempt. It seems the case that whether you like or not –
    we are creeping steadily away from a best-of-breeds approach to
    building out datacenters. Everyone yaks endless about the
    commoditization of IT – and it’s happening right before our eyes. Each
    of the major OEMs – HP, IBM, Dell have been for sometime junking their
    valued partner relationships in effort to seal their customers into a
    one-stop solution. Of course, IBM are probably the company that’s most
    famous/notorious for this approach. In recent years, HP have been
    steadily improving their HP ProCurve stuff to the degree that they no
    longer feel the need to promote/resell Cisco switching gear. To me the
    VCE announcement amounts to 4th OEM provider coming along to this
    party. So in short while you will be able to CHOOSE which OEM to
    shackle yourself too. This choice will be limited to the “Gang of Four”.
  • Duncan Epping – How to avoid HA slot sizing issues with reservations
    When you select a specific percentage that percentage of the total
    amount of resources will stay unused for HA purposes. First of all
    VMware HA will add up all available resources to see how much it has
    available. Then VMware HA will calculate how much resources are
    currently consumed by adding up all reservations of both memory and cpu
    for powered on virtual machines. For those machine that do not have a
    reservation a default of 256Mhz will be used for CPU and a default of
    0MB+memory overhead will be used for Memory.

VMware, HP’s Converged Infrastructure, and the Private Cloud

VMware, HP’s Converged Infrastructure, and the Private Cloud

Steve_Herrod Posted by Steve Herrod

Chief Technology Officer and Senior Vice President of R&D

This week HP introduced their
Converged Infrastructure Architecture, which is appropriately described as “a
blueprint for chief information officers to create elasticity in their
technology environments.” This blueprint unlocks currently siloed datacenter
resources (including compute, storage and network components) and, with the
help of virtualization, integrates them into a pool of very fluid resources
that can be smartly and safely allocated to the applications running on top.

Put another way, HP has unveiled a template that helps customers easily
build what many are now calling a “private cloud.” The general idea of a
private cloud is to bring many of the good traits associated with today’s
public cloud vendors (e.g. elasticity, efficiency, self-service, and
usage-based resource charges) to a company-owned and operated
datacenter—where IT is often more comfortable with their ability to meet
performance, availability, and compliance requirements.

VMware vSphere™ was explicitly designed for
building the private cloud, and HP BladeSystem Matrix’s out-of-box experience
and well-integrated management will help customers more quickly and more easily
realize the full capabilities of VMware vSphere. What’s more, even as customers
reap the benefits of their private cloud, they’re also laying the foundation to
leveraging public cloud resources. Virtual machines are well-encapsulated and
largely location independent. Working with HP, we can offer tools and a
complete portfolio of services that help customers continue to maintain the
control and security they have in their datacenters as they begin to leverage
resources in the public cloud. The resulting “hybrid” cloud is depicted below.

Image001

Infrastructure and application management in this new world is
incredibly important, too, and HP’s capabilities integrate quite well with
VMware vCenter™ to push the envelope on this front. I particularly like the
integration work HP has done to bring their Insight software capabilities into
VMware vCenter. You have to register to see it, but there’s a great
demonstration of this at minute 62 of the VMworld 2009 general
session
.

I’ll stop here in the interest of keeping this blog short, but I did
just want to highlight again the excitement I have over holistic solutions
built for the fully virtualized datacenter that help enable the promise of the
private cloud.  If you would like
to see and hear a lot more about VMware and HP’s Converged Infrastructure,
be sure to also check out the video
from Bogomil Balkansky
, VMware’s VP of Server Product Marketing.

VEEAM SOFTWARE SAVES THE DAY AT VMWORLD 2009

 Allgemein, Updates, VMware, VMworld / VMworld Europe  Kommentare deaktiviert für VEEAM SOFTWARE SAVES THE DAY AT VMWORLD 2009

GreenPages Pushes Virtual Desktop Infrastructure to Limit with 2,400 Desktop Images on Six ESX Servers; Veeam Successfully Monitors Vast Environment

Columbus, Ohio, October 1, 2009 – Veeam Software, award-winning provider of systems management tools for VMware virtual datacenter environments, proved the importance of building scalable products from the ground up for the virtual world when its monitoring solution successfully monitored a record-breaking 2,400 desktop images on six ESX servers during VMworld 2009.

Veeam Monitor, rapidly becoming the industry standard for VMware performance monitoring, capacity planning and troubleshooting, saved the day when GreenPages Technology Solutions, a national IT consulting and integration company, built a massive virtual desktop infrastructure (VDI) demonstration on the show floor at VMworld 2009. Once GreenPages achieved its goal of provisioning 400 desktop images on each of six ESX servers, the massive implementation surpassed the capabilities of the monitoring tool in place. GreenPages asked Veeam Software to step in.

With no advance notice or planning, within 10 minutes, Veeam Monitor was installed, licensed and properly configured. It accurately reported the new desktop image count, and within the next 30 minutes, it showed the full input and output load, as well as statistics that the solid-state drive fiber-connected logical unit numbers (LUNs) provided to the system.

“Veeam Monitor has exceptional scalability and is now our preferred standard for VMware management software,” explained John Ross, GreenPages Chief Technology Officer. “It monitors extremely high density levels of virtual machines, yet it has a small footprint and is very easy to install. Customers don’t want to purchase additional hardware to monitor their systems, and they certainly don’t have to with Veeam Monitor.”

Ratmir Timashev, President and CEO of Veeam Software, said GreenPages amazed the VMworld audience with its cutting-edge system. “We were thrilled with the opportunity to prove our monitoring software could successfully capture data from a system being pushed to its breaking point,” he said. “Veeam Monitor’s scalability speaks for itself and is a solid example of why we build products from the ground up specifically for the virtual world.”

Top 5 Planet V12n blog posts week 44

This was probably one of the toughest Top-5’s to write as I had the week off this week. I basically had to catch-up with a whole week of Planet V12n. One of the most annoying things about it is that half of the blogs on PlanetV12n enabled „content summary only“. Yes I know you will have a couple of extra visits, but isn’t blogging about getting people to read your content instead of being „numbers“(visits) focused? Now that I got that off my chest lets move on to what this article is about. It’s about the 5 top articles this week:

  • Vaugn Stewart – VCE-101 Thin Provisioning Part 1 – The Basics & VCE-101 Thin Provisioning Part 2 – Going Beyond
    Like the thick format, thin VMDKs are not formatted at the time of
    deployment. This also means that data that needs to be written must
    pause while the blocks required to store the data are formatted. The
    formatting operation only occurs on demand at anytime an area of the
    virtual disk, which has never been written to, is required to store
    data.
  • Chad Sakac – Solid State Disk will change the storage world…
    But surely, if you were looking for performance, you wouldn’t use the SATA disk, right? You would probably use a 15K RPM FC disk. Those cost about $1000. They do about 200 random write IOPs. So, you would need 20 of them to do what that $115 SSD could do. That’s 0.2 IOps per dollar – or 170x more expensive than the SSD on a IOps/$ basis. Oh, you think SAS 15K drives are a better deal? They are – than FC disks. A 15K SAS disk on Pricewatch costs about $210, and they also do about 200 IOps. that’s 0.95 IOps per dollar – or 37x more expense than the SSD on a IOps/$ basis.
  • Luc Dekens – dvSwitch scripting – Part 4 – NIC teaming
    The double Service Consoles and vmKernel connection might look confusing at first. But when you select one these connections, the vSphere client will show you to which uplink a specific connection is going.

    To increase the availability of the dvSwitch, I will show how to add two pNics and how to activate and configure NIC Teaming.

    When I created the dvSwitch I configured it for two uplink ports (per host). Since I’m adding two pNics, I will first have to change the maximum number of dvUplink ports.

  • Gabrie van Zanten – Design tips for VMware vSphere 4
    Recently at the Belgium VMUG I gave a presentation in which I covered some design tips for VMware vSphere 4. I talked about some business decisions that, how boring they may seem, are crucial for your design. I covered some security requirements you should check with the security department of the organisation and of course advised good capacity planning which also is very important for your design.

    What the average geek found most interesting where topics like: “What size of ESX host will you buy?”, “How to run vCenter in a VM”, “VMFS best practises”, “Understanding queue depth and lun size” and more….

  • Simon Gallagher – iSCSI LUN is very slow/no longer visible from vSphere host
    Due to too many SCSI reservation conflicts, so hopefully it wasn’t looking like corruption but a locked-out disk – a quick Google turned up this KB article – which reminded me that SATA disks can only do so much 🙂

    Multiple reboots of hosts and the OpenFiler hadn’t cleared this situation – so I had to use vmkfstools to reset the locks and get my LUN back, these are the steps I took..

    You need to find the disk ID to pass to the vmkfstools –L targetreset command, to do this from the command line look under /vmfs/devices/disks

Top 5 Planet V12n blog posts week 43

Compared to the weeks before this week I had an easy week. A design review and some pre-sales related work, it is something else for a change. Something else that’s new and exciting; I started working with John Arrasjid and Steve Kaplan on revising a book. It’s not going to be a deep technical book, but it will focus more an introduction to virtualization. More on this later. It’s top 5 time again, here we go:

  • Scott Sauer – Get Thin Provisioning working for you in vSphere
    So now that we have some of the basics out of the way, I wanted to
    share my thoughts on thin provisioning.  Like many organizations, we
    get requests from our customers that err on the side of caution.  They
    want to plan for the worse case and ensure that their project and/or
    application isn’t setup for failure.  I don’t blame them really, I do
    it myself all the time when I make coffee at home.  I always end up
    making more coffee than I typically drink, just in case I might need
    that extra charge.  The best way to do that is pad it, request more
    than what you might really need, just in case something comes up down
    the road.  Virtual machine disk storage in some cases fits this same
    profile.  If my coffee maker granted me access to hot coffee on demand,
    I would stop making extra coffee.  Thin disks can give your end users
    that capacity on demand so you can gain control of the padding effect
    that typically takes place in most corporate organizations.
  • Rich Brambley – Thoughts and Images of vCloud Express
    When vCloud Express was announced along with the vCloud API at VMworld 2009 in September I decided to sign up and try building VMware virtual machines (VMs) in the Cloud for myself. Being able to provision infrastructure as a service (Iaas) virtually with only a credit card has a certain useful appeal to me, and I wanted to see firsthand exactly what can be done and how much it costs.

    This post summarizes my experience and touches on Terremark’s various options for building VMware Cloud VMs. I also quickly describe/illustrate the difference in charges for Linux versus Windows Cloud servers. This post contains a lot of screen shots, and at the end I’ll offer some opinions on the usefulness of vCloud Express and where this service might make sense for IT shops.

  • Chad Sakac – Cloud Storage – what the hell is EMC building?
    The implications on storage infrastructure of these internal/external cloud models profound. Think of it this way… The vast majority of storage users in enterprises today have a provisioning model where the first step is “tell us whether you want 250GB or 500GB, whether it’s SAN or NAS, and the protection level – then wait a couple weeks as we process the request”. Of course, to fulfill the request, they purchased a wad of storage a year ago. How much did they buy? More than they needed – because god forbid they err with not enough (and in doing that ensure that they err completely in the opposite direction!). And, of course, it’s generally pretty “thickly” provisioned – and even if it is thin, it’s doled out and managed app by app, so the “pools” tend not to be too wide.
  • Vaughn Stewart – VCE-101: Oracle On VMware Without Limits
    After a brief hiatus I am very eager to return to the ‘Virtualization Changes Everything’ series, and today’s post is an impromptu addition to our syllabus. Recently fellow VMware vExpert Steve Kaplan of INX published a rather thought provoking post rallying for the acceleration of the transformation to a 100% virtualized datacenter. Steve waxes poetic advocating acquisition decisions spanning compute, storage and network should be driven by their contribution to data center virtualization success and I would encourage everyone to read it.
  • Duncan Epping – DRS Deepdive Part 1 and Part 2
    Keep in mind that when you change the “Migration Threshold” the value of the “Target host load standard deviation” will also change. In other words the Migration Threshold dictates how much the cluster can be “imbalanced”. There also appears to be a direct relationship between the amount of hosts in a cluster and the “Target host load standard deviation”. However, I haven’t found any reference to support this observation. (Two host cluster with threshold set to three has a THLSD of 0.2, a three host cluster has a THLSD of 0.163.) As said every 5 minutes DRS will calculate the sum of the resource entitlements of all virtual machines on a single host and divides that number by the capacity of the host:

    sum(expected VM loads) / (capacity of host)
