NetApp - The Virtual Storage Guy

SPEC SFS2008 Verifies You Can Run Faster on Fewer Disks with PAM

NetApp is the only storage vendor focused on reducing storage hardware footprints. Evidently discussions surrounding the use of storage saving technologies in a production environment must be upsetting to the traditional storage array manufactures as anytime I discuss the technologies that enable such environments the comments sections of my posts inevitably end up reading (and smelling) like the zoo after the monkey cage has endured a pooh-flinging outburst.

It is my premise that the attempts of the traditional legacy storage array vendors to dissuade customers from considering and implementing storage savings technologies is a self-severing and not a community driven interest. Maybe my statement is a bit inflammatory but just consider the following statements regarding the use of data deduplication from a well-known traditional storage manufacture VP...

”Typically, when storage admins run into I/O density problems, they have two fundamental approaches: more disks, or faster disks.”

“By spreading the load on more spindles, I/O density can be reduced. However, you now require more storage, power, cooling, etc. -- which kind of tends to defeat the whole premise of data deduplication to begin with.”

“The other approach is to use faster disks -- either disks that spin faster, or perhaps enterprise flash drives. Invariably, these cost more as well -- again tending to defeat the whole premise of attempting to save money through data deduplication.”

Statements like this are clearly meant to caution customers against the use of ‘risky’ new concepts (reduction of storage footprints) and the primary enabling technology (data deduplication). So is the information shared in this warning accurate?

VCE-101 Thin Provisioning Part 2 – Going Beyond

This is the second installment of a two-part post focusing on the thin provisioning capabilities native to vSphere. If you haven’t read Part I - The Basics, I’d suggest you do so before proceeding. We've covered a lot of content which you really should have a solid grasp of before proceeding.

In part I, I covered the basics of thin provisioning and how it operates with any storage platform. In part II we are going to expand upon a number of the points introduced in part I with a focus on how the storage virtualization functionality in Data ONTAP enhances VMware's thin provisioning and the over arching goal to reduce both the CapEX and OpEx associated with storage in the virtualization space.

Anatomy of a Virtual Disk

Let’s begin where we started in part I, by reviewing different disk formats. This time let’s consider them with the virtual disks operating at 70% storage capacity.

- The Thick Virtual Disk

Again this is the traditional virtual disk format which we all know rather well. From this image you will notice do not receive any storage savings in the datastore, yet we do receive 30% savings on the storage array.

If you're asking, "how can a thick VMDK consume less storage on the array?"
You'll need to go back and read Part I

- The Thin Virtual Disk

In this image we have the thin provisioned virtual disk and as you can see we are receiving a 30% storage savings in both the datastore and on the array.

- The Eager Zeroed Thick Virtual Disk

In this last image we have an eager zeroed thick virtual disk which provides us no savings at either the datastore or on the array.

VCE-101 Thin Provisioning Part 1 – The Basics

This week’s VMware Communities Roundtable featured one of my favorite people at VMware, Paul Manning who spoke on thin provisioning. This topic is the inspiration for today’s VCE post. Reducing storage costs is top of mind and it's gonna take some time covering thin provisioning so let’s begin!

Virtualizing a Datacenter

I am not exaggerating when I share with you that every customer I meet with has elaborate plans to virtualize most, if not all, of the Intel based servers within their data center, yet deploying this new architecture is challenged to move from a portion to a majority of the footprint due to storage costs (both CapEx and OpEx). I'd like to summarize the message from these meetings for you, which goes something like this…

“We love server virtualization! With VMware we’ve reduced our server footprint and are targeting more systems to virtualize.”

“We love converged Ethernet! With Cisco we’ve reduced our port counts and are targeting to have a single platform for voice, data, and user access.”

“Storage costs are out of control, can you help? Prior to virtualization we roughly ran 20%-30% of our servers on shared storage arrays. Virtualization is forcing every VM onto shared storage. What do we do?”

Now Available: The Virtual Storage Console vSphere Plug-in

Since VMworld 2009 one of the recurring questions posted to me on Twitter has been. “When will NetApp release the VSC?” – Wait no longer, the VSC is available for download via NOW.

For those of you unfamiliar with the VSC, it is a vCenter 4.0 plug-in that simplifies the configuration and management of NetApp, IBM, and Virtualized 3rd party arrays. The VSC supports ESX/ESX 4.0 along with monitoring and reporting only capabilities with ESX/ESXi 3.5.

The Virtual Storage Console is the next generation of the NetApp ESX Host Utilities Kit. Gone are the days on installing the EHU into the service console of ESX or cursing NetApp for the lack of support with ESXi. The VSC adds a NetApp tab into vCenter that enables one to:

• Manage ESX/ESXi storage connectivity

• Report ESX/ESXi storage details

• Accelerate resolving storage connectivity related support cases

• Optimize VM storage options for performance and availability

My I introduce you to the Virtual Storage Console version 1.0…

Mike Laverick on vStorage Plug-in Integration

This morning began with catching up on my VMware related reading. Like many of you I have a list of ‘must reads.’ Over at RTFM Education Mike has shared his PowerPoint presentation on vStorage integration, which he delivered at the 1st Scottish VMware User Group Meeting.

Mike thanks for sharing! This slide deck provides a great overview of the current state of the union and what customers can deploy today (or in the very near future) from NetApp & EMC.

I'd suggest that you check out the PPT and just in case you were afflicted by temporary insanity and have yet to subscribe to RTFM, do so now!

A Follow-up on HP TechDay 2009 with an Invitation for You!

This week HP demonstrated several of their technology offerings to the storage community, and as a part of this event HP provided a hands on lab where attendees to 'kick the tires' of their storage technology offerings. As a part for this lab attendees were able to complete the same tasks with storage arrays and management tools from EMC and NetApp.

These types of educational experiences can really benefit the community by showcasing one’s enhancements and differentiation. I fully endorse these types of labs, sharing information empowers the user community and raises the bar in terms of what we must develop in order to remain an industry leader… except this isn’t what happened.

According to multiple tweets attendees were stating that tests designed to demonstrate storage integration with Windows systems and VMware were the command line interface and Filerview. This caught my attention as these aren't the tools NetApp recommends for our install base. A quick glance at a few of the sites covering the event confirmed the use of these legacy tools.

In fairness I need to highlight that HP did follow the steps provided in our storage best practices documents for VMware TR-3428 (VI3) and TR-3749 (vSphere). I would like to share with you that we are in the process of updating these documents with a goal of reducing their sizes by approximately 40%.

We hear the VMware community loud and clear - simplicity equates to scaling an environment.

Attention CEOs: Pay $75 per Virtual Desktop for Storage

Recently both NetApp and EMC published VDI whitepapers with our mutual partners VMware and Cisco. Both papers are very solid and should result in robust infrastructures; however, the solutions are far from equal and I’d like to take 5 minutes of your time to share with you some interesting points of comparison.

Sure the EMC paper focuses on UCS platform while the NetApp paper focuses on a Nexus infrastrucutre, but that’s not what I want to discuss. Yes, the EMC architecture running on Fibre Channel over Ethernet and the NetApp solution is leveraging NFS, but that’s not what I’d like you to consider either.

The level of differentiation I want to highlight is the cost per desktop in both of these solutions. Why cost? Simple, it is the number one hindrance to virtual desktop adoption.

EMC: The Storage Most Integrated with VMware? – The Conclusion

We here at NetApp have been burning the proverbial midnight oil getting ready for VMworld, and in doing so I have put off posting a number of blog entries.

I trust you will be very impressed with our VMworld line up. If you can’t make the show make sure to hit our Virtualization YouTube Channel, as all demos will be posted there when the show opens.

A week and a half ago I posted the first half of a discussion that started with some recent customer meetings and the claims by a storage vendor that they were the most integrated storage with VMware. This post received a fair amount of discussion and comments for which I am grateful. You may note I closed that original post asking for feedback and fact checking of the data shared.

Mike & Scott - Thanks

I’d like to take a minute to personally thank Mike Laverick and Scott Lowe for participating in our preview of the Rapid Cloning Utility 2.1 and the Virtual Storage Console. These technoilogies and more will be on display in the NetApp booth at VMworld.

Neither Mike nor Scott require introductions. Both are respected leaders in the virtualization market and both were kind enough to share their thoughts in online reviews.

VMworld 2009 – Storage Integration Sneak Peek

I trust you are as excited as I am with VMworld just around the corner. In case you missed it, we have a lot going on in San Francisco. Brian Gracely has a published number of posts covering the details of our Breakout Sessions and the sessions featuring either NetApp Partners or Customers over at the Virtualization Effect.

For more details click here, here, and here.

If you’d like some insight as to Dave’s plans to present during our Keynote presentation check out this post in the NetApp Communities.

The Storage Most Integrated with VMware

In yesterday’s post I made an effort to clarify the level of integration between VMware and a storage vendor claiming to have the greatest level of integration. While I craft the follow up to that post I’d like to offer you a preview of one of the integration technologies that will be made available and on display at VMworld.

EMC: The Storage Most Integrated with VMware?

My apologies for being away from the blog for a bit. I’ve been heads down either meeting with customers or working with my team as we wrap up the final details for our VMworld presentations and demos. Today I’d like to share a true story from these recent customer visits. In a number of these meetings, multiple customers shared a similar story of their EMC sales teams stating that EMC was the storage most integrated with VMware.

I guess if I didn’t work in the storage industry, I’d suspect this claim would seem very plausible. Why wouldn’t it be true? EMC is parent company of VMware and as such they probably have tighter engineering relationship that result in solutions exclusive to EMC… Right?

VCE-101: What's Next with Deduplication?

Welcome to the latest post in our series entitled ‘Virtualization Changes Everything’

In our last post we discussed the CapEx savings provided by data deduplication of both production storage capacity and storage array cache. Deduplication is fundamentally changing the data center and it appears that there’s more on the horizon. I’d like to share with you what I call ‘Data Center Ethernet Acceleration’.

Overview

“"Some call it a software mainframe others call it cloud, it depends on when you were born" – Steve Herrod, CTO, VMware

When discussing multiple applications on a single hardware platform I prefer the term ‘software mainframe’. I think this is due more to my time working with VMware products rather than my age. I still recall my introduction to this concept back in 2001.

The Epiphany - I Had One, You Want One?

Recently I was visiting customers and prospects in the North East and during one of our meetings the customer stated, “…what NetApp is doing, in terms of storage virtualization, make us feel like NetApp is much more aligned with the goals of VMware than their parent company…”

This praise was shared while the customer told us how EMC is working to earn back their VMware (storage) business. Apparently the EMC team stating something to the effect that more companies run VMware on EMC than on any other storage platform and that the numbers from these surveys validated this claim.

The customer shared with us that what was very interesting in this data set was that NetApp's gains in market share was much more impressive than EMC's legacy market share.

VMware Communities Roundtable Podcast #48

Yesterday Chris Gebhardt and I had the privilege of being guests of John Troyer on episode 48 of the VMware Communities Podcast. On the podcast we discussed numerous topics regarding storage with VMware including Multipathing, performance, storage virtualization, DR, and backup and recovery.

vSphere Introduces the Plug-n-Play SAN

With today’s release of vSphere, VMware has introduced numerous new features and technologies all designed to advance the virtual evolution of our data centers. With this release VMware and their storage alliance partners have delivered Plug-n-Play SAN storage connectivity. As you begin downloading the final bits, refreshing your labs and planning your upgrade path to vSphere I’d like to dig into the considerations of and how one can deploy a robust, reliable, and greatly simplified P-n-P SAN architecture with vSphere and NetApp.

A New Era for Virtual Desktops

We are entering into an interesting time in the industry witnessed by the release of VMware View. View Manager, View Composer, Thin App, and Offline Desktop are well positioned to accelerate the adoption of virtual desktops in datacenters and to remote access devices.

Today I’d like to share some thoughts specific to reducing storage costs with VDI or View.  A major component in VMware View Composer is Linked Clones, which provides the ability to deploy hundreds of virtual desktops from a single desktop image.  In addition to storage savings, customers will be able to update deployed desktops deployed with View Composer by patching the master desktop image.

Recently I have received a number of inquiries as to how View Composer and Linked Clones integrate with NetApp’s storage saving Dedupe and zero cost provisioning FlexClone technologies.  I’d like to take this time to discuss this topic and how VMware and NetApp are engineering the best of breed virtual desktop solutions.

I will caution you in advance, this post is a bit lengthy because we have much to share and discuss.
