Three Key Storage Features Missing in Mac OS X “Lion”

June 13, 2011 By Stephen 3 Comments

Apple is not in enterprise storage company to be sure, and news from WWDC dashes any hopes we had for ZFS and iSCSI support. USB 3.0 seems a foregone conclusion, but Apple seems intent on ignoring it as long as possible. Although I welcome the new storage features included in Lion, it is disappointing that these were left out.

Key Storage Features in Mac OS X 10.7 “Lion”

June 6, 2011 By Stephen 7 Comments

Apple’s not an enterprise company or a storage company, but Apple does have enterprise storage features in their operating systems. And Mac OS X 10.7 “Lion” is a great case in point. From Versions to Time Machine Local Snapshots to AirDrop, Lion brings some storage love, and NFS, SMB, and Xsan are there, too. Let’s look at what’s new and key in terms of storage in the latest version of Mac OS X.

Apple Customers Vent Over Ex-Xserve RAID

February 20, 2008 By Stephen Leave a Comment

Apple’s business customers do not appear amused at the company’s exit from the enterprise storage space, but it was the quiet way that the company dumped the Xserve RAID product from their lineup that really irked. “XRAID” customers were left wondering whether they made the right choice, and if the company’s support for the defunct […]

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 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 Kipling’s Dirigibles to the Jet Age

May 13, 2012

I don’t get much chance to read for pleasure, but two things I’ve been reading recently spurred my imagination. After reliving the advent of modern transportation in the solid non-fiction Jet Age by Sam Howe Verhovek, I stumbled upon two pieces of speculative fiction from an unlikely source that predated everything presented there.

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.

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.

Storage Changes in VMware vSphere 5.1

September 4, 2012

As I have done since version 3.5, I’m charting the storage changes in VMware’s latest release of vSphere, 5.1. Unlike version 5, which included many new technical storage features, 5.1 mainly tweaks existing features and adds these new elements to the mix.

Not All 802.11n Networks Are Alike

July 2, 2011

Buyers of 802.11n wireless network equipment should not assume they will see a great benefit right out of the box. Most will have to enable by hand a high-performance configuration including wide channels and 5 GHz operation. And some client devices may never reach the levels of performance expected by consumers due to hardware limitations.

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.

ZFS Is the Best Filesystem (For Now…)

July 10, 2017

ZFS should have been great, but I kind of hate it: ZFS seems to be trapped in the past, before it was sidelined it as the cool storage project of choice; it’s inflexible; it lacks modern flash integration; and it’s not directly supported by most operating systems. But I put all my valuable data on ZFS because it simply offers the best level of data protection in a small office/home office (SOHO) environment. Here’s why.
