NetApp - The Virtual Storage Guy

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.

A Customer's Findings: VMware on NetApp vs EMC

It must be ‘Brief Post Friday’ as I keep getting pinged with great info to share all the while I have several other deadlines to meet (I guess its another evening of working until midnight).

I have the privilege of sharing with you the following report compiled by a rather large customer which compares the results of virtualization consulting engagements completed by EMC and NetApp.

How Heavy is your ESX Load?

I can’t tell you how often we are asked for tips around optimizing the performance of virtualized applications. Resolving performance related issues can require investigating a number of variables ranging from the virtualized application including the GOS settings and the data layout, and all the way down to the configuration of the ESX/ESXi server itself.

VCE-101: Deduplication: Storage Capacity and Array Cache

Welcome to the first session in a series of blog posts entitled ‘Storage 101 - Virtualization Changes Everything’

Data deduplication was originally introduced in Data ONTAP 7.2 in July of 2006 as a technology that enhanced the NetApp Disk-to-Disk (D2D) backup offerings. Coincidentally VMware released VI3 around the same time in June of 2006, and shortly thereafter customers began using these two technologies together to virtualize their servers and storage footprint.

For today’s post we’re going to dive into the realm of storage efficiency and discuss data deduplication and it’s impact in production storage capacity and storage array cache specifically within a virtual data center.

The Format of this Series

As I stated when I decided to kick off these posts I want to share these topics with a wide audience and in order to do so each session will begin with a high level overview of the technology and its value followed by the technical details.

vSphere on NetApp Best Practices Released

I am please to share with you that this morning our new Technical Report, TR-3749: vSphere on NetApp Storage Best Practices, has been released. I’d like to thank Mike Slisinger, Larry Touchette, and Peter Learmonth for all of their assistance in the production of this TR.

I’d like to take a few moments to share some of the core enhancements covered in the report.

Everything Old is New Again

I’ve been saying ‘everything which is old is new again’ over the past few years as it is very evident within the server virtualization landscape. Well low and behold Google announces plans to develop their browser, Google Chrome, into its own operating system and I believe the same phrase applies.

I vividly recall my second job in the IT industry, when I was at a regional Internet Service Provider. 'Back in those days' the big news were the plans of Netscape to release a Java based operating system delivered via Netscape Navigator.

I’m a huge fan of Google and I hope they can pull this off. I wonder how much of what was learned in developing Android will be leveraged in the new OS.

You know what would really impress me? What if Google got into the server virtualization business – now that would be cool! Hey they're already in the cloud...

VMware Co-Brands TR-3428

There's an update to our VI3 storage best practices technical report. There's no technical content updates to be concerned with, instead I would like to share that TR-3428 version 4.5.2 has been officially co-branded by VMware.

This update is basically a quality assurance seal which states that the engineering teams at VMware and NetApp have reviewed and verified the contents of this technical report and the recommendations included within are truly best practices.

This wasn't always the case as some of the content in TR-3428 were truly ground breaking not too long ago. For example the dual VMkernel network designs had on occasion lead to additional discussions and configuration validations prior to implementation.

Kudos to all involved, now I think we've come to a time to let this document rest and focus on the vSphere TR.

Storage 101 – Virtualization Changes Everything

Updated July 12th - Syllabus revised

Welcome all to Storage 101, I’ll be brief below is our syllabus and the topics we will cover leading up to VMworld. The format of these posts will begin with a high level introduction to the technology followed by all of the technical gory details. I am hoping that those who want the ‘why’ can be satisfied up front, and these who want the ‘how’ can continue reading.

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.
