FalconStor Brings VAAI Support To Every Storage Array

September 1, 2011 by Stephen Leave a Comment

I do not necessarily endorse or recommend FalconStor NSS over competing products from more familiar names, but I commend them for adding VAAI support. There the first small vendor to do so, and their software virtualization platform spreads the availability of this important software capability.

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.

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.

Processing and Scheduling Thin Provisioning

February 22, 2011 by Stephen 3 Comments

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.

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.

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.

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?”

The End of Unlimited Data – Part 1: The Buffet

June 2, 2010

The headlines are all over the blogs: AT&T announced today that they are doing away with “unlimited” data plans and replacing them with limited packages at lower prices. I’m not going to repeat the news – Boy Genius Report has the best overview I’ve seen. Instead, I’m going to explain why I think this is a positive move for everyone involved, including AT&T, the customer, and the US wireless phone industry as a whole. This first post talks about the buffet mentality that got us here.

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!

Thinking About Storage In a New Way, From Cloud to Flash, with Dropbox and Fusion-io

July 23, 2013

I’ve been a storage revolutionary for quite a while, looking for new ways of data storage rather than technologies that perpetuate the same old approaches. That’s why I’m excited about the implications of two very different API access methods announced by Dropbox at DBX and by Fusion-io today at OSCON.

The Myths of Standardization

December 15, 2011

I certainly benefit from standardization of the world around me, and I welcome interoperability and interchangeability as well as the price and product selection advantages. But I am not blithely focused on standardization above all else. I will happily use a proprietary solution if the alternative is inelegant, ineffective, or insufficient.

Hands-On Review: Unicomp Spacesaver M Keyboard for Mac

July 3, 2012

I would not hesitate to recommend the Unicomp Spacesaver M to Macintosh users used to an original IBM Model M, and I am admittedly a tough customer. I wish that Unicomp would update their website, packaging, logo, and keyboard graphics, but none of this really matters as your fingers press the keys. If any keyboard is worth $100, it is the Unicomp Spacesaver M!

It’s Time To Move Beyond Passwords (Especially On Web Sites)

January 8, 2016

Sure, single sign-on puts all your eggs in one basket. But this is vastly preferable to trusting that hundreds of third-party baskets are secure, especially when they prove on a weekly basis that they aren’t! It’s time to put distributed passwords behind us and switch to systems like SAML, both for businesses and consumers.

Scaling Storage Is Hard To Do

June 4, 2013

Data storage isn’t as easy as it sounds, especially at enterprise or cloud scale. It’s simple enough to read and write a bit of data, but much harder to build a system that scales to store petabytes. That’s why I’m keenly focused on a new wave of storage systems built from the ground up for scaling!
