The need for I/O virtualization and lack of practical short-term alternatives breathes new life into Infiniband For many IT managers, Infiniband immediately brings HPC (high-performance computing) to mind. In fact, this much-snubbed connectivity protocol has found vindication in HPC, where its minimal latency, sustained transfer rate, and gentle impact on CPU cycles have found much appreciation. It's not that Infiniband is unknown among the lower tiers of enterprise computing, but vendors have predominantly favored other protocols, such as FC (Fibre Channel) and, more recently, the controversial newcomer, iSCSI. Which is a pity, because Infiniband could very well be the ultimate... more
Equipped with a can of air spray and sophisticated data hunting techniques, attackers can rebuild disk encryption keys from fragments of data in memory Just when you thought you could sleep easy with disk encryption, here comes a wake-up call from the Center for Information Technology Policy at Princeton University. In just a few pages, the center's research team proves that disk encryption is easy to defeat if your attacker is skilled and determined enough.When the laptop is in sleep mode, whatever is stored in memory remains in memory, including encryption keys. Big deal, you might think, the laptop asks... more

Ingenuity in storage is evolutionary -- but clustered storage could be the revolution that replaces RAID Defining the single-most significant change in storage I have seen throughout the years could easily lead to multiple discussion threads. After all, technological achievements are plentiful. Take the emergence of SATA and SAS, for example; or the staggering increase in capacity of a wide range of storage media; or the ongoing acceptance of Ethernet as an alternative to Fibre Channel for block storage connectivity. The list could go on almost indefinitely. Yet examining the individual tiles of the increasingly complicated storage puzzle more often... more
VMware and LeftHand Networks up the virtualization ante with a joint offering Last week, at VMworld Europe in beautiful Cannes, LeftHand was showing, I am told, the Virtualization Solution Kits (VSK), a joint offering with VMware that promises to bring together the best of virtualization to SMBs and beyond. I had to skip Cannes this time, but I installed in my lab the nuts and bolts of the kit. Essentially, the solution kits offer well calibrated doses of VMware Virtual Infrastructure 3 (VI3) and LeftHand VSA, Virtual SAN Appliance for VMware. For the full scoop on the products involved, peruse... moreContinue reading"Virtualizing the whole shebang"
InfoWorld's storage expert zooms in on best practices for planning, selecting, and deploying new storage technology Notice anything different this week? That's right, Storage Insider has a new name. From here on out, it's all about advice. Why the change? There are several reasons, the most important of which is to better align this space with my day-to-day hands-on experience putting the latest technologies through their paces. The storage industry has changed significantly since Storage Insider launched in 2002 -- and not just in terms of technical advances. Storage vendors' communications strategies have also changed, leaving behind the controlled trumpeting... more
