The Coming Wave of Declustered RAID

In this podcast, the Radio Free HPC team looks at the coming wave of declustered RAID solutions designed to address the problem of ever-increasing RAID rebuild times. With 5 Terabyte drives in the wings, RAID cluster rebuild times are becoming impractical.

Dan is impressed with what IBM is doing in this area with GPFS.
Henry thinks these larger drives harken the death of RAID-5 and RAID-6.
Rich has been keeping a close watch on Xyratex and their ClusterStor GridRaid implementation.
Read the original paper on Declustered RAID by Garth Gibson and Mark Holland.

The RONNIEE Network Architecture

In this podcast, the Radio Free HPC team looks at the newly announced RONNIEE Network Architecture from A3 Cube. Rich did a slidecast with their CTO this week, but Dan and Henry need to know more and see this thing for themselves.

Following that, the conversation veers off into a grab bag of tech news for the week:
  • Dan's is still recovering from a rootkit that infected his business computer. We seem to recall that he was always backlogged before this happened, but we'll let it slide.
  • Henry is lamenting the lack of Google Fiber coming to Minnesota. Since Google tends to piggyback on the fastest Internet pipes, it looks like the state will forever be a third-world country in terms of bandwidth.
  • Rich is excited about the Outernet project, which hopes to launch a series of satellites that will provide free Internet connectivity worldwide to anyone who wants it.
