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 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!

The Prime Directive of Storage: Do Not Lose Data

December 12, 2014

People call on storage devices and systems to do lots of things, from accelerating I/O to copying and sharing data. But at the heart of it all, storage arrays really have just one job: Do not lose data!

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.

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.

A Fairy Tale of Two Storage Protocols

September 23, 2014

It’s clear how this fairy tale ends. So many companies are using “S3 plus” as their standard interface, and even inside their solutions, that it’s safe to say it’s won the cloud storage API battle. But S3 isn’t a finalized spec – the industry will extend and improve it over the coming years. Soon we’ll have a cloud storage standard based on S3, just like we have a LAN file services standard based on CIFS.

The Fat Middle: Today’s Enterprise Storage Array

August 31, 2014

Ask any project manager if it’s possible to deliver something that is fast, good, and cheap, and they’ll laugh. The phenomenon known as the Iron Triangle limits just about everything in the world from meeting all three conflicting requirements. Yet, for the last two decades, enterprise storage array vendors have been trying to deliver just this. How’s that working out?

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.

Regarding My Symbolic Links and Good Reads

April 16, 2015

I’ve been told that my shares drive traffic to the blogs I read. I’m thrilled that I can share great writing with you in this way, and I hope you find it valuable! But just in case you don’t, I hope you’ll take advantage of the fact that I filter these posts for you into “Symbolic Links” and “Good Reads” so you’ll find it easier to ignore them.
