Qumulo: An Enterprise Storage Startup Focused on Scale, Simplicity, and Efficiency

November 20, 2012 by Stephen 2 Comments

Enterprise storage is perhaps the most innovative area of IT these days, with exciting startups springing up right and left. Today, that scene welcomes Qumulo, who are building a new storage platform focused on scalability, efficiency, and simplicity. Qumulo catches my eye for two reasons: The team is heavy with Isilon experience, and CTO Aaron Passey really impressed me with his work at Clustrix.

All Business Development All The Time!

May 4, 2009 by Stephen Leave a Comment

If you work in the enterprise storage, storage networking, virtualization, or security industry, listen up! Otherwise, this post is not for you! I hope you, or a representative from your company, will join me and the folks from Nirvanix and my friends like W. Curtis Preston and Marc Staimer, Charles Curran and Dan Gordon from Valhalla, and just about […]

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.

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!

Infographic: Real-World Port Throughput Relative To Thunderbolt (Formerly Light Peak)

Just how fast is 10 gigabits per second anyway? To help out, I’ve prepared another napkin-tastic infographic!

Deduplication Coming to Primary Storage

September 16, 2008

Although deduplication of storage is nothing new, with Data Domain and other making hay with the technique for years, it has never been ready for prime time – reduction of active primary storage applications like email and databases. Instead, deduplication has been relegated to second- or third-tier status, deduplicating archives and backup data. But change is in the air, and deduplication vendors are starting to bustle towards the bright lights of primary storage.

My 2012 Project: Improving Energy Efficiency

January 3, 2012

I am in the process of upgrading my own home to make it more energy efficient. I do this mainly as an exercise of faith and science, since my electric and gas bills are not currently all that expensive. But I just can’t countenance burning 10 times more electricity than I need to, even if I can afford it. It’s also an exercise in geekiness, since today’s lighting alternatives and appliances have an undeniable techno-cool factor about them.

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!

Defining Failure: What Is MTTR, MTTF, and MTBF?

July 6, 2011

Most computer industry vendors use the term â€œMTBFâ€ rather indiscriminately. But IT pros know that systems do not magically repair themselves, at least not yet, so MTTR and MTTF are just as important!

Virtualized and Distributed Storage: This Time For Sure!

September 2, 2014

We were never able to achieve storage virtualization in mainstream enterprise IT because we lacked the ability to identify and move data non-disruptively. This has been solved by caching and distributed storage solutions, and it’s only a matter of time before the legacy need for centralized storage falls away.

A Complete List of VMware VAAI Primitives

November 10, 2011

VMwareâ€™s introduced the â€œvStorage APIs for Array Integrationâ€ (VAAI) in vSphere 4.1, and block-heads like me went nuts. Weâ€™ve been trying to integrate storage and servers for decades, and VMwareâ€™s APIs finally allowed this to work in truly seamless fashion. But the world of VAAI is a thicket of bizarre naming and puzzling functionality. Some VAAI primitives are ignored or even hidden! Letâ€™s take a look at the complete list.
