VMware PSP and SATP in Plain English

VMware's PSA is awash in abbreviations and options

I am often questioned during my Storage for Virtual Environments seminar presentations about VMware’s Pluggable Storage Architecture (PSA). This system is fairly straightforward and concept: VMware provides native multipathing support for a variety of storage arrays, and allows third parties to substitute their own plug-ins at various points in the stack. But the profusion of acronyms and third-party options makes it difficult for end-users to figure out what is going on.

Tech Field Day Boston: Virtualization and Baseball

Join us (in Boston or online) for Tech Field Day 6 in two weeks!

A few weeks from now, I will head off to Boston for a special event focused entirely on server virtualization. Tech Field Day 6 brings together so many great things that it’s hard for me to summarize it!

IBM Adds VAAI Support to XIV and SVC

IBM today announced VAAI support for SVC, and promised it for the DS8000 as well

VMware’s vStorage API for Array Integration (VAAI) is one of the most-important storage technology advances of the decade, allowing the ESX to integrate and coordinate operations with supported enterprise storage arrays. IBM was notably absent from the party, but they’ve turned on the VAAI heat, releasing full support for the XIV and SVC and promising DS8000 in the near future.

I Don’t Care If You Claim It Works (The Support Matrix Blues)

Now this is a respectable support matrix! (Saint Vitus' Cathedral, Prague)

As an IT professional, I subscribe to a simple rule: I won’t recommend a solution that’s not listed in the support matrix or HCL. “I don’t care if it works, only that it supported,” is really a cynical overstatement of this position. Of course I care whether or not a solution works! But merely claiming that something works is not sufficient for me to recommend it. I need to be able to demonstrate that it’s a supported configuration. Show me the listing, and I’ll start recommending it.

Changes in Technology Drive Changes in IT Organizations and Roles

Servers, storage, and networks may be interconnected, but most large IT organizations keep the administrative teams from mixing. But the next-generation virtual data center might change that!

Lots of my IT infrastructure management clients are talking about how the advent of Ethernet/IP and virtualization is changing the roles of storage, server, and network administrators. The evolution of the storage role in particular in enterprise IT organizations has been a topic of particular interest to me for a while: I definitely remember thinking about [...]

Where Will Virtualization of Data Center Infrastructure Take Us?

Virtualization decouples the

Virtualization of IT systems decouples physical infrastructure from logical resources, hiding complexity and enabling new capabilities. However, not all potential benefits of virtualization have meaningful value outside IT circles: Too many of our discussions revolve around the very complexity that virtualization technology should be hiding! True business value is derived from transformed virtual resources in the next-generation data center, not the incremental capacity gains of virtual servers. But how will we get there, and what will this future look like?

Granularity: The Hidden Challenge of Storage Management

Mueslix

Many storage challenges focus on the conflict between data management, which demands an ever-smaller unit of management, and storage management, which benefits most from consolidation. Developing data management capability that is both granular enough for applications and scalable enough for storage is one key to the future of storage.

April Fools 2011 Roundup

SE9QC

I love April Fools day. Like Halloween, it gives us all a chance to take ourselves a little less seriously and just have some fun. And the best April Fools pranks are those that point out real limitations in our thinking and mindset. That’s always been my April 1 goal: Why not combine Wi-Fi and PoE? And doesn’t the “giant iPod Touch” sound like a hoax?

vSphere 5 To Include vStorage API for Token Ring Integration

VMware shocked the world today, pre-announcing an important addition to the vStorage family of APIs found in their marquee vSphere family of products. The vStorage API for Token Ring Integration (VATRI) promises to ease the transition to converged networks featuring the emerging Fibre Channel over Token Ring (FCoTR) storage protocol. According to a recent report by The D’Plata Group, FCoTR is set dominate the enterprise storage market, and this integration is a confident step in that direction.

How To Select a Virtual Server Backup Product?

I have been asked to write an article for TechTarget on the subject of selecting a virtual server backup product. I’d like to request input for this piece, and hope we can work together to produce a useful list of recommendations. Note that this isn’t a buyer’s guide like the DCIG effort: There will be no exhaustive lists of functions and features here. Instead, I’m writing about the options available in a more general sense.
