STEC may not have been quite ready to reveal their next-generation ZeusRAM solid-state disk (SSD), but they are demonstrating it anyway at EMC World in Boston this week. The ZeusRAM is a fundamentally different animal from the existing ZeusIOPS drive in one critical way: Rather than using flash memory for primary data storage, the ZeusRAM uses DRAM. This improves reliability and longevity and ought to raise the bar on performance as well.

Over the past few years I’ve been asked to troubleshoot and explain why cloning a virtual machine (VM) from a master template would take a longer time than expected more than once.

Although it’s rare in the PC world, multipath I/O is not new in enterprise IT. I’ve been juggling paths to storage and networks as long as I’ve been a systems administrator, and that’s a bit longer than I care to admit. But the proliferation of technologies has made it difficult to understand path management. What’s the difference between “dual active” and “active/active”? Is “active/passive” really that bad?

NetApp CEO Tom Georgens is quoted as dismissive of multi-level tiering, saying: “The simple fact of the matter is, tiering is a way to manage migration of data between Fibre Channel-based systems and serial ATA based systems.”

One of the “key features” of XIV is the wide striping of data across all spindles, a concept we’re seeing more and more. Have you ever wondered what the point is?

Ever since Microsoft and Intel declared that the combination of Windows and Nehalem could deliver over a million iSCSI IOPS, I’ve been curious about just how they did it. What black magic could push that many I/Os over a single Ethernet connection? And what was on the other end? Now Intel has revealed all in a whitepaper, and the results are surprising!

HP recently commissioned Tolley Group to benchmark their BladeSystem c7000 against the Cisco UCS 5100. The short report focuses on two results, and reads like so many competitive benchmarks in the IT industry: Tolley focuses on metrics that highlight the strength of HP’s solution and the weaknesses of Cisco’s. What’s the real value of pinpoint maximum-performance benchmarks like this?

“Maximizing Hyper-V iSCSI Performance with Microsoft and Intel” might sound like another “blah blah” marketing piece, but a little birdy tells me that this webcast will drop a bombshell about iSCSI performance.

See the Drobo in Action, a wide coverage of various Drobo Performance Stats. Here are some stats collected with running Drobo as a direct attached storage and using some benchmarking tools to compile these results. All the performance stats are collected using different criteria’s that can affect the performance of the Drobo. Also used various connection methods including USB and Firewire to obtain these stats.

I usually welcome discussion (and even argument) about the things I know best: There is always more to learn, and the best insights come through engaging those who disagree with us. But some ideas have been argued so well for so long that they deserve enshrinement. For example, although non-scientists like to argue about evolution [...]
