Get ready for 2.5, 5, 10, 25, 40, 50, and 100 Gb Ethernet, all at once!

Faster Ethernet Gets Weird

“One size fits all” doesn’t work for Ethernet, but this proliferation of speed options sounds like trouble without automatic capability negotiation. It’s nice to have options, but the IEEE must remain focused on interoperability and rein in the interests of the various companies proposing next-generation Ethernet technologies.

The Raspberry Pi is an awesome UPS monitor with the open source Network UPS Tools package

Automated UPS Monitoring for vSphere with NUT and Raspberry Pi (Cheap!)

NUT is a wonderful and extensible power management framework, and the Raspberry Pi is an awesome platform on which to run the UPS monitoring drivers and upsd server daemon. Even if you’re not running vSphere, a Pi running NUT makes sense for the connected servers found everywhere today.

Blatant Fraud At Amazon: Do Something About It!

This is not a link blog, but I just had to highlight this blatant fraudulent activity at Amazon reported by my friend Lee Badman. A quick glance shows that the same thing is widespread – too-good prices on items offered off-Amazon with payment through gift cards. It’s a straight-up scam, and I wonder how many people have been hurt by it and why Amazon hasn’t done anything to stop it!

The third-generation drobo is just about the perfect home storage device

Generation 3 drobo: Fall In Love All Over Again

I remain a huge fan of drobo generally, and the third-generation drobo remains the best choice for home storage. It’s the perfect storage device for the long haul, and the performance improvements make it a no-brainer. Get one.

VMware has adopted NFS 4.1

vSphere 6: NFS 4.1 Finally Has a Use?

Way back in the 1990’s, UNIX admins delighted in upgrading from NFSv2 to NFSv3. Then NFSv4 came around and … crickets. Now VMware has become the first major/useful/mainstream application for NFSv4.1, so the floodgates are open! But are they?

10 Mysteries The Lost Finale Definitively Settled

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.

Travel isn't always sunny and glamorous!

Frequent Flier Kung Fu for Novices

If you’re careful, even an infrequent flyer can rack up valuable points and maybe even elite status. But don’t do anything foolish, and don’t be fooled by the promises of first-class treatment. Even top-tier frequent flyers sit in coach most of the time!

VMware mucked with vSphere licensing again...

Storage Changes in VMware vSphere 5

Once again, VMware added a ton of new storage enhancements to vSphere. With storage rapidly becoming the limiting factor in scalability and performance of virtual machine environments, this is no surprise. Also not surprising is the fact that major features like Policy-Driven Storage and Storage DRS (along with SIOC) are exclusive to “Enterprise Plus” licenses.

VASA allows a "provider" application to tag vSphere storage with a "capabilities" string

What is VMware VASA? Not Much (Yet)

VMware is adding storage integration features to their flagship vSphere server virtualization product line at a rapid pace. From backup to enterprise array offload, VMware is staking their claim. But information about one new storage feature in vSphere 5 has been scarce: The true nature of the Storage API for Storage Awareness (VASA) is only just beginning to be revealed.

Clustering sounds great, but it's awfully taxing to keep all the nodes consistent!

Scaling Storage In Conventional Arrays

It is amazing that something as simple-sounding as making an array get bigger can be so complex, yet scaling storage is notoriously difficult. Our storage protocols just weren’t designed with scaling in mind, and they lack the flexibility needed to dynamically address multiple nodes. So my hat is off to these companies and others who have come up with clever ways to maintain compatibility while scaling out beyond the bounds of a single storage array.

The Myths of Standardization

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.

Top of rack flash, bottom of rack capacity, and software gluing everything together!

The Rack Endgame: A New Storage Architecture For the Data Center

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!
