Apple Revs Xsan and Kills Xserve RAID?

February 19, 2008 By Stephen 3 Comments

Apple has an odd relationship with enterprise computing. Their Xserve server products are strong, as is Leopard Server, and they have an excellent SAN file system, Xsan, that they just updated. Yet, Mac OS X is the last major operating system with no volume manager (thanks to the antiquated HFS+), and it looks like the […]

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 I/O Blender Part 1: Ye Olde Storage I/O Path

May 23, 2012

This old-fashioned, predictable storage I/O path was deterministic and decipherable: The server, the switch, and the array all had enough information to do their jobs effectively and efficiently.

Microsoft’s Overlooked Innovation

February 15, 2010

It’s fun to bash Microsoft. It’s easy, too, with Apple solidly conquering the high end of the PC and mobile markets and Google’s command of the Internet. But how fair are these articles skewering Microsoft, such as “Microsoft’s chronic lack of innovation” published today at Techworld? I suggest that Microsoft innovates as well as, if not better than, any other massive company. But no one innovates like an outsider.

Why Are PCIe SSDs So Fast?

June 12, 2013

The world of storage can be confusing, with obscure terms hiding massive differences in technology and performance. Such is the case for the latest PCI express SSDs: They are much faster than traditional SAS or SATA SSDs, but many aren’t sure exactly why. In this article, I will try to explain the real difference.

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.

My Visit to Bletchley Park

August 3, 2012

Bletchley Park is much more than a museum. For those interested in the history of computing, like me, or World War II buffs, it’s a must-see. The reconstructed Bombe and Colossus computer are truly breathtaking, and I find myself drawn to the stories of codebreaking that took place here. I highly recommend a visit!

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.

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.

Replacing Google Reader With Feedbin and Reeder

May 5, 2013

I am an avid Google Reader user, so I’m thoroughly annoyed by Google’s decision to kill it as of July 1. But there’s no stopping the tide, so I’ve made the move to Feedbin as a Reader replacement as of today. It’s a slick, snappy web application with a committed developer and, critically, support for Reeder, my favorite offline RSS reading application. Let’s hope this works!
