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.

My “On the Road” Video Recording Kit
Good equipment can make the difference between an amateurish embarrassment and professional production when it comes to video recording. The combination of the Zi8 and my pair of microphones collect good enough source material to keep me in the latter category. Combined with the capabilities of Apple’s iMovie software, I can produce respectable videos anywhere I happen to find myself.
IBM Adds VAAI Support to XIV and SVC
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.
Back From the Pile: Interesting Links, February 25, 2011
So there it is. Intel’s Light Peak was launched as Thunderbolt in the new Apple MacBook Pro line. What else happened?
Processing and Scheduling Thin Provisioning
Although the core issues with thin provisioning revolve around communication, it presents unique challenges to the storage array as well. We talked about granularity of pages, and the comments for that piece were extremely enlightening. Now let’s consider another key factor: Scheduling.
