VMware PSP and SATP in Plain English

June 6, 2011 By Stephen 4 Comments

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.

Storage Changes in the VMware vSphere 4 Family

April 21, 2009 By Stephen 6 Comments

VMware officially launched their next-generation (version 4) enterprise family of products today under the “vSphere 4” name. As I’ve been doing for the last few major ESX releases, I’m focusing this post on the storage changes present in vSphere 4.

GPS Time Rollover Failures Keep Happening (But They’re Almost Done)

This is week “1111111111” in the GPS system. Tomorrow morning it will roll over to week “0000000000”. How well will various systems handle this change? Not well, judging by what we’ve seen so far!

Ranting and Raving About the 2018 iPad Pro

I remain enthusiastic about the iPad Pro, despite getting a scratched screen and my concerns about durability. It’s a worthy successor to the original and offers enough improvements that I’d recommend the upgrade for just about anyone who uses their iPad for serious work. It’s still not yet a laptop replacement, but this is due more to a lack of desktop-class software for iOS than anything in Apple’s control.

The Rack Endgame: Converged Infrastructure and Disaggregation

September 19, 2014

As Iâ€™ve written about what Iâ€™m calling the â€œRack Endgameâ€, the specter of converged infrastructure hasnâ€™t been far from my thoughts. As others have pointed out, disaggregation of servers, networks, and storage doesnâ€™t require a rack-sized stack; it can exist in a rack-mountable chassis and is already on sale!

10 Mysteries The Lost Finale Definitively Settled

May 25, 2010

The series finale of Lost didn’t settle every question, but it did settle many of the long-running questions raised by fans. Although my live viewing was frustratingly complicated by failed transmission equipment at ABC affiliate, WEWS, I was able to watch the entire episode thanks to iTunes. So let’s settle the things that can be settled regarding Lost.

Cisco’s Trojan Horse

September 15, 2014

Industry watchers like me have long wondered when Cisco will transform itself into a full-line IT infrastructure vendor. This strategy was tipped in 2009 as Cisco barged into the server market with UCS. But one leg of the stool is still missing: Storage remains the province of Cisco partners like EMC and NetApp.

Nimble Storage Rolls Out an All-Flash Array

February 24, 2016

It took longer than I expected for Nimble Storage to introduce an all-flash array, but their AF7000 looks to be a very credible offering. They’re targeting XtremIO and Pure with their marketing, but I expect HP, Dell, and especially NetApp to be cross-shopped more frequently. In that fight, I expect the Nimble AF7000 to be very attractive indeed!

Go Get a ProtonMail Account and Protect Your Online Life!

July 19, 2017

It’s an easy decision: Get a free ProtonMail account and use that as your verification address for important financial and social media accounts. Keep using whatever email account you like for regular communication, but don’t mix security and communication!

Microsoft: Kill the Craptops Before They Destroy Windows!

January 7, 2013

Release after release, Microsoft pushes Windows forward. Yet the operating system is continually undermined by the “value-focused” low-end machines pushed by the majority of OEMs. This race to the bottom has tarnished Windows for a decade and now threatens to derail Windows 8. Microsoft must do something to stop the crap before it’s too late!

On the Death of Innovation, or “These Kids These Days!”

May 21, 2012

An obnoxious meme has returned to the fore lately, claiming that innovation is dead. The hippies did it, or maybe it was the Internet, or even a decline of America. But nothing could be further from the truth, and statements like this make me question the perspective of the speaker.

It’s Fine To Mount Hard Drives On Their Side Or Even Upside-Down

August 13, 2016

Have you ever wondered if mounting a hard disk drive on its side or even upside-down affects its lifespan or reliability? According to every drive manufacturer, it’s perfectly acceptable to mount a hard disk drive in any orientation as long as it’s not tilted and has sufficient cooling.
