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.

PowerPath To The Virtual People

April 22, 2009 By Stephen 5 Comments

Hiding in the shadow of the huge VMware vSphere 4 announcement was a very interesting introduction by EMC: PowerPath/VE. As I mentioned in my post on storage changes in vSphere 4, PowerPath/VE plugs into the new pluggable storage architecture (PSA) found in vSphere 4 versions of ESX and takes over the decision-making and heavy-lifting tasks related to communicating with storage systems.D

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 2018 iPad Pro is a Beast!

The third-generation iPad Pro is a great machine but also a bellwether of change at Apple. It will be very hard for the rest of the mobile and client computing industry to keep up with this kind of progress!

Why You Should Never Again Utter The Word, “CIFS”

February 16, 2012

CIFS is not the network storage protocol used by Microsoft Windows, and many other clients. The protocol used to share files over a LAN by the majority of personal computers is called SMB. I wish everyone in the industry would get that through their heads.

What More Could Alan Turing Have Accomplished?

October 7, 2012

Many of you have probably heard the name of Alan Turing, but most of those probably don’t appreciate the extent of his contributions. To say that he invented the modern world is an overstatement, but he did dream up the computers we see around us today, and helped win World War II in the process. But the story of Alan Turing is as much about exclusion and defeat as it is of genius.

Fasting to Mitigate Jet Lag: Surprise! It Works!

February 11, 2013

I’m a frequent traveler, and thus a frequently suffer from moderate jet lag. It’s just so hard to adjust to a new time zone! But I recently stumbled on a simple method many claim helps your internal clock re-calibrate to travel. After trying it out on my trip to Australia last week, I’m convinced it can help!

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.
