TMS has doubled its flash-based RamSan-630's Fibre Channel speed from 4 to 8Gbit/s, meaning 10GB/sec bandwidth, and is working on eMLC-based flash product. The 630 is a 3U enclosure holding up to 10TB of single level cell (SLC) flash with up to 10 Infiniband (IB) or Fibre Channel ports. It delivers 10GB/sec across the IB ports …
I would like to address the no Single-Point-of-Failure claims that TMS makes in this article.
Mirroring is simply not the same as an N+1 design. It puts the management and recovery outside the storage array which is simply suboptimal. It requires maintaining two solutions - the storage and the external management. Redundancy becomes extremely expensive: two appliances instead of one, double the sparing inside each storage appliance. After replacement, one has to rebuild the ENTIRE storage, where in most cases the failure could be local and requires minimal rebuild.
