IBM Adds VAAI Support to XIV and SVC

May 9, 2011 By Stephen 3 Comments

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.

VMware VAAI Storage Array Support in Plain English

February 8, 2011 By Stephen 18 Comments

The most exciting enhancements in VMware vSphere 4.1 is the addition of vStorage API for Array Integration (VAAI). This new API allows VMware ESX to offload storage processing functions to capable storage arrays, reducing the workload on the server hardware in introducing new and exciting possibilities for performance and efficiency. VAAI in ESX 4.1 includes three separate capabilities: block zeroing, full copy, and hardware assisted locking.

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!

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.

Why I Am Biased Against FCoE

October 21, 2011

I am biased against FCoE because it’s too new to be blithely and broadly recommended for production enterprise use. That’s all. Yes, the standards are standardized and there are products extant. But that’s not enough for me.

How Fast Is It? A Storage Infographic

October 29, 2010

How fast is a hard disk drive? How about the various flavors of SATA and Fibre Channel? Check out this handy Pack Rat infographic to answer the question, “how fast is it?”

Sony QX100 Lens Camera: Ruined by a Flaky iOS App

October 7, 2013

I was thrilled by the possibilities of adding a professional-quality camera sensor and lens to my iPhone, so I immediately pre-ordered Sony’s DSC-QX100 “lens camera”. It held so much promise, not just as a real innovation but also as a major productivity tool. That’s why I’m angry to write this, a scathing review of the horrid software that ruins the QX10 and QX100 experience. Do not buy this device.

What You See and What You Get When You Follow Me

May 28, 2019

Social media ought to be social, not just a broadcast platform. That’s my feeling at least. It’s been a while since I’ve ranted about “write-only” social media accounts, so I thought I might as well do it again. And at the same time, I thought I would update you on my promise to the people who read, follow, and interact with me online.

The Rack Endgame: A New Storage Architecture For the Data Center

September 3, 2014

Top-of-rack flash and bottom-of-rack disk makes a ton of sense in a world of virtualized, distributed storage. It fits with enterprise paradigms yet delivers real architectural change that could “move the needle” in a way that no centralized shared storage system ever will. SAN and NAS aren’t going away immediately, but this new storage architecture will be an attractive next-generation direction!

From LAN Manager and SMB to CIFS: The Evolution of Prehistoric PC Network Protocols

March 22, 2012

Computers aren’t much good on their own. This simple fact was evident even at the dawn of the microcomputing age, and has never been more true today in the “post-PC” world. If the standard microcomputer is the “Wintel” box (Microsoft’s Windows, Intel’s CPUs, and all that implies) then the standard network services protocol is SMB. So let’s take a nice deep dive into SMB, past, present, and future!

Thoughts on the Modern Miracle of 3D Printing

July 28, 2015

Although I enjoy my AIO Robotics Zeus 3D printer, I’m under no illusions that it’s an economical or practical device. It’s a toy that takes me into the future, and I love being there!
