Changing Windows VM Boot Volume Block Size with vSphere Converter

First things first. This is unsupported by Microsoft, VMware, Amazon, Google, AOL, Geocities, John Madden, Edgar Allen Poe and your mother. Also, not generally a good idea.

Storage providers (NAS, SAN, HCI, Cloud, etc.) typically have preferred block sizes for the volumes created on top of their file system. Alignment is also super critical within a VM and you can read a great post about alignment on Duncan Epping’s blog here. Applications also have some best practices around formatted volume cluster sizes (or allocation units, or block size) based on their default average IO size. For instance, for Microsoft MS SQL, Microsoft highly recommends using a block size (allocation unit, cluster size – will be used interchangeably here) of 64k on any volume containing a database. More detailed info here.

Most often, when deploying an application, you will install the binaries on the root drive (C:\) and place the data on a secondary disk. Most applications allow this, some do not. For those instances where the do not and the application has been installed on the boot drive (C:\), you’re stuck with the cluster size you chose on installation (default of 4k).

If the application cannot deal with it’s data on a different device/directory than its binaries, and the binaries cannot be moved, you’re typically stuck unless you want to re-install and migrate data.

If you want to live on the edge, you might be able to convert the boot drive’s block size using VMware’s free vSphere Converter.

This is a step-by-step for that process. Continue reading

SimpliVity – 23 Months in, $1B And Growing

Fun news in the Hyperconverged Infrastructure space today: SimpliVity has announced both a $175million Series D funding round and an over $1B valuation. I was fortunate enough to join the company just after last year’s $58 million round and am thrilled to be here as we surpass $276 Million in total funding to help drive our hyper-growth. We’ve grown 130% from last year, to 400+ employees and are anticipating/planning on being around the 800 people mark by the end of the year. This current round of funding will put us well on the way of funding this major expansion.

The funding and valuation make a of couple points. First: Hyperconverged Infrastructure is a very real, and very massive market. A report from Gartner estimates that, by 2018, there will be $18B spent annually on integrated systems, of which Hyperconverged Infrastructure is a significant portion. And, depending on which research firm’s religion you subscribe to, the total addressable market is somewhere between $100B and $400B.

Second: investors believe in SimpliVity. It started out (as all young companies do) with investors believing in a vision and leadership. Well, that got us through the first couple of rounds. 9 months after the OmniCube went GA, investors started seeing the fruits and wanted to be a part of the first wave of expansion. This brought us through the C round. Now that another year has gone by, something interesting happened. Waypoint Capital began as a SimpliVity customer, seeking to simplify their datacenters and provide global management, backup and disaster recovery on a single platform. Only SimpliVity could supply this, and currently 100% of Waypoint’s IT across 5 datacenters runs on OmniStack. They were so impressed that they were compelled to lead a new round of funding, along with some previous investors. We’ve grown from funding solely by investors who buy into the vision to investors who not only believe in the vision, but whose own infrastructures have been transformed by SimpliVity’s Hyperconverged Infrastructure.

For perspective on the valuation, SimpliVity has reached the $1B mark after only 23 months of shipping product. Let that sink in. Under 2 years, making it one of the fastest growing infrastructure companies in IT, ever. We’re taking that as a hefty vote of confidence.

One of the unheralded aspects of SimpliVity is the global footprint strategy: full North America and EMEA availability, sales, and support from day one. Most companies will start in North America and spread slowly into different international regions. Since release, more than 50% of sales have been outside of the U.S., and in 2014, we expanded with resellers in 50 countries and employees in 18.

I’m excited to be a part of SimpliVity and am proud of the market and investor validations from vision to results. Don’t just take it from me, take if from our customers.

Virtualization Field Day 4 – Austin, I am IN you!


I’ve been fortunate enough in my career to be a part of a group of IT folks that have been able to take part in a Tech Field Day, a series of industry events bringing together technology purveyors, community influencers, analysts, enthusiasts, tweeter folk and grey beards (none of these are mutually exclusive of the others). It’s a place that brings new vendors with exciting visions of technology and old vendors with shiny newness, both of which provide an exciting look at the ever changing landscape of enterprise IT.

Besides my general fondness of Stephen Foskett (and his glorious peanut brittle) and Tom Hollingsworth, I’m excited to be a part of the event from the vendor perspective, getting to attend with my friends Jesse St. Laurent and Brian Knudtson from SimpliVity to give delegates (and viewers) a deeper look into how we do Hyperconverged Infrastructure and what’s possible when you do deduplication and compression in real time in-line.

But where the real action takes place is the delegates. The industry folks (admins, engineers, bloggers, analysts, friends) that come to these Field Days are the linchpin to its success and to its enjoyment. Most of the people going I’ve had the pleasure of knowing for a while and meeting in person previously, and some I’ve only interacted with online and am thrilled to finally meet in person.

Spirit of the UNparty

Way back machine:

The year was 2012. VMware was having this little get together (VMworld) in San Francisco and had decided to toss in a little soiree at the end to show their appreciation for their customers and partners. They rounded up this small indie east coast artist to play some music (Bon Jovi) and got some food and drinks and other miscellaneous entertainment stuffs.

While I greatly appreciated the gesture and great effort to put together said soiree, I am not a big fan of these large engagements and at the same time, not a big fan of Bon Jovi (don’t tell my 80s rock loving spouse). So after talking with several other in the same boat, Jim Millard, Matt Leib and I decided that we’d spread the word and meet somewhere local and small and have some drinks together. Without meaning any offense to VMware’s party, we called it the UNparty and invited others who felt similarly.  About 50 people showed up to the Toronado that night. Many beers were consumed, laughs were had, and connections were made. Good times.

Fast forward to 2013 and VMware again (surprise!) decides to have another gathering of virtualization peeps in San Francisco. This time, the location and festivities were more elaborate (at AT&T park) with bigger, more ‘not 80s’ bands Train and Imagine Dragons. Cool! More people wanted to go to that, but there were still folks that were not into that large of an event, and to people’s surprise, not everyone wanted to hear Train or Imagine Dragons. So, again, we had an UNparty at the Chieftain. This time, about 100 people showed up and we actually had a sponsor – Computex (thanks!).

Present day machine:

VMware is (again! Man, they must really dig this stuff) bringing folks from all over the world together for a week of virtualization goodness. This time, the band for the week’s party is The Black Keys. Part of the premise of the UNparty was that I (nor my partner in crime, Jim) wanted to see the band that was lined up to play. And if it came to be that we DID want to see the band, well, someone else would likely not want to see them and they could ‘organize’ the UNparty if they wanted to. There’s never been anything tying myself or Jim to it other that it was something else to do with the community as an alternative to VMware’s party.

All that being said, I’ve been wanting to see The Black Keys for a very, very long time. And, it turns out, that Jim also would like to see them. So, the UNparty for 2014 will have to be passed on to another to organize. Or it doesn’t have to happen at all. That’s the spirit of the UNparty.

So, if you want to organize it, fly my friend, be free.

SimpliVity as Visionary – Just Getting Warmed Up

First off, congrats to SimpliVity and other vendors for being included on Gartner’s inaugural Converged Infrastructure (no?) Integrated Systems Magic Quadrant (MQ)! The report not only further validates this direction for infrastructure and the importance of convergence, but also highlights the breadth of scope within this space.

Reading over the report, they used a very broad definition for Integrated Systems (read more about that at Ron Singler’s blog here), which in turn lead to them not using the term ‘converged infrastructure’. The graphic depicts Gartner’s basic qualification for inclusion in the Integrated Systems category:


This resulted in the inclusion of everything from broad workload systems (VCE, SimpliVity, etc.) to workload specific systems like Oracle Exadata and Teradata. Equally interesting, however, was the exclusion of Pivot3, Scale, UCS, VSAN, Maxta, Atlantis ILIO, EMC ScaleIO,  etc.

If you look at Gartner’s Inclusion and Exclusion Criteria section (p.s. you can download the report here), you will see that they specifically excluded software-only solutions and most ‘Server SANs’ which require customer based installations and layering and only included systems that fully integrated storage (which is why no UCS without Netapp). But just because you fall into Gartner’s definition does not mean you make it into the report (e.g. Pivot3, Scale). What does this mean for vendors in the current report that will go to a software based model in the future? Or those that may OEM their software only solution to hardware vendors? Not sure, but Gartner can certainly change their criteria at their choosing.

It’s a fascinating space with explosive growth that leads to the necessity of including vendors both new and old. Note that SimpliVity had only been GA for 5 months when the data for this report was gathered. I can’t think of such a young company being this far in the Visionary quadrant, save perhaps Amazon Web Services, and even then, they had a running start (more on that over at Gabe Chapman’s blog).

What does this mean for SimpliVity? We’re certainly not taking a ‘we’re just glad to be here’ stance. It’s great affirmation of our trajectory and we’re just getting warmed up.

Let’s Simplify Things

Over the past few decades, many technologies have come into the datacenter to increase both the quality and number of services. Some of these have been to solve direct technical problems (WAN acceleration), some have been to solve capacity and utilization problems (deduplication, virtualization, SAN/NAS), and some to solve ‘keep the business alive’ problems (backup, BC/DR, etc.). With each of these solutions came another box to consume more space, more power, more cooling, more money, and on and on. On top of the physical ‘mores’ is the ‘complexity more’. More software. More management consoles. More throats. Though, these silos of infrastructure did bring less of a few things: less productivity, less agility, less flexibility, etc.

Enter convergence. At the base of it, convergence is about simplicity and efficiency.  As Stu Miniman said, “Customers, however, are not looking to buy “convergence””, they’re looking to solve the problems of complexity, inefficiency and inflexibility. And not just solve them for one application, silo or data set, but to solve them at scale.

A number of vendors come straight to mind when talking about convergence, but one thing that’s certain is that this a change in how the business of the datacenter is done. As we know, change is not always met with open arms within an industry. As Andre Leibovici pointed out in his linking to an article about a change in an industry: “disruption will always be challenged by standards”

Traditionally, datacenter projects include deploying a storage product, a backup product, a replication product, a compute product and a virtualization product, often taking a number of days to a number of weeks to implement. Enough. Let’s change this. Let’s simplify.

For this reason, I’m excited to join an amazing team (Gabriel Chapman, Ron Singler, Dave Robertson, Mario Brum, etc.) at SimpliVity. Their take on hyperconvergence is, I feel, the most complete to date and their efficiency and simplicity of collapsing silos of datacenter technologies is refreshing. I’m excited about integrating more than just storage, compute and a hypervisor in a platform, but also fine grained policy based backup, deduplication, compression, wan optimization, replication and more in a building block architecture with one management console.

I’m extremely grateful to my friends at Computex for the opportunity to work with them helping customers along the virtualization path and I look forward to continuing conversations about simplifying datacenters. Let’s do it.


TL:DR – I’m joining SimpliVity: yay :-)

Upgrading vCenter Operations Manager OS to SLES 11 SP2

With the release of vCenter Operations Manager 5.8 (now at 5.8.1), an upgrade to the appliance’s underlying OS also needs a bit of patch, which makes sense since SLES 11 has been out for a while (January 2013). It’s a pretty simple upgrade, but you have to do it from the OS itself, not the vC Ops admin console. Continue reading

Winds of Change

Way back in 2012 (remember that year? Yeah, those were the days), I was invited to join a great team at Nexenta Systems. On this team, one of my primary roles was to manage the internal deployment of VMware’s vCloud Director. The use case was pretty typical: carve up resources for Engineering, Sales, Support, Training, etc. for them to each have their own datacenter playground. It was really fun to train, watch and work with each group use the resources to develop their vApp catalogs and see some lightbulbs go on for what’s possible for Infrastructure as a Service: from the Training group developing full on, repeatable, deployable in minutes labs for students running nested instances of both NexentaStor and vSphere to Support spinning up analytics machines to process core dumps or test a process/change set quickly only to destroy them minutes later.

vCloud PowerCLI ExtensionData UpdateServerData Limit

Part of my cleanup from the vCloud Suite 5.1 upgrade is migrating everything off of the *Any storage profile. A piece of this is setting the DefaultStorageProfile property for templates, which by default is blank (meaning the *Any profile). I’ve written a function that I’m using to update these in mass:

function set-templateVmDefaultSP($templates,$sPName)
    foreach ($template in $templates){
        write-host "Changeing defaultStoragePofile for VMs in $template"
        $vms = $template.extensiondata.children.vm
        foreach ($vm in $vms){
            $vm.defaultstorageprofile = "$sPName"

This passes a list of templates and a storage profile name, iterates through the template’s VMs, changes/sets the DefaultStorageProfile and sends an XML update back to vCloud with the changes.

This was working all well and good until I ran into this error:

PowerCLI C:\scripts\vcloud> $template.extensiondata.updateserverdata()
Exception calling “UpdateServerData” with “0” argument(s): “The provided XML has too many elements: 3340. The maximum is 2,048.”

Change vCloud vApp/VM Storage Profile with PowerCLI

VMware has done a lot to open up the APIs for vCloud with the 5.1 release, however it still leaves much to be desired. One of the nicer things is the ability to change a storage profile for a VM. However, you need to know the HREF for the storage profile that you want to change to. This wasn’t so easy to get (I would love to be able to use a “get-storageProfile” PowerCLI cmd-let), but thankfully, Jake Robinson (@jakerobinson) and the VMware Community to the rescue:

This script uses PowerCLI for Tenants (which cannot be installed on the same box running the ‘regular’ PowerCli). Taking his prompt to build an XML file from an HTTP GET to a vCloud HREF, we can retrieve storage profiles from any OrgvDC you have rights to. From this XML, we can assign a storage profile to a VM (or in this case, every VM in a vApp) based on it’s name and the Org you’re logged into. I modified his script a little bit, because if we pass an Org to the function, we don’t get the storage profiles, but if we pass an OrgvDC HREF, we automatically get the storage profiles (because storage profiles are assigned to Org vDCs and not globally to an Org). This reduces the number of function calls needed.

All this script needs is your vApp name and desired Storage Profile name.

What this also addresses is the ability to migrate all vCloud VMs off of the “*Any” Storage Profile.

# This function does a HTTP GET against the vCloud 5.1 API using our current API session.
# It accepts any vCloud HREF.
function Get-vCloud51($href)
 $request = [System.Net.HttpWebRequest]::Create($href)
 $request.Accept = "application/*+xml;version=5.1"
 $response = $request.GetResponse()
 $streamReader = new-object System.IO.StreamReader($response.getResponseStream())
 1$xmldata = $streamreader.ReadToEnd()
 return $xmldata

# This function gets an OrgVdc via 1.5 API, then 5.1 API.
# It then returns the HREF for the storage profile based on the $profilename and

function Get-storageHref($orgVdc,$profileName)
 $orgVdc51 = Get-vCloud51 $orgVdc.Href
 $storageProfileHref = $orgVdc51.vdc.VdcStorageProfiles.VdcStorageProfile | Where-Object{$ -eq "$profileName"} | foreach {$_.href}
 return $storageProfileHref

# Get vApp, Storage Profile and OrgvDC names

$vappName = read-host "vApp name"
$profileName = read-host "Storage Profile"
$orgVdcName = read-host "Org vDC Name"

$orgVdc = get-orgvdc $orgVdcName

#Get storage profile HREF

$profileHref = Get-storageHref $orgVdc $profileName

# Change each VM's Storage Profile in the vApp

$CIvApp = Get-CIVApp $vappName
Foreach ($CIVM in ($CIvApp | Get-CIVM)) {
 $newSettings = $CIVM.extensiondata
 $ = "$profileName"
 $newSettings.storageprofile.Href = "$profileHref"
 Write-Host "Changing the storage profile for $ to $profileName"
