In the beginning of the millenium, Fibre Channel ruled the roost. Nothing could touch it. SATA and SAS were a ways away. SCSI was used in smaller storage systems. Networked storage meant a large central server with ports. SANs were on the rise.
In HPC you have to move lots of data. Huge amounts of data. Performance bottlenecks are no fun.
FC is a slow technology. It is designed to connect as many disks as you can together for SAN architecture. It is not designed specifically for HPC, to move data as fast as possible. Yeah, I know, there are a few spit-takes from folks who think FC is fast.
Put it this way. FC4 is a 4Gb/s network protocol. Thats about 500MB/s. FC8 is an 8 Gb/s network protocol. Thats about 1000 MB/s.
10GbE is a 10 Gb/s network protocol, or about 1200 MB/s. 40 Gb/s QDR ways in at a hefty 3200 MB/s.
As I said, FC4 and FC8 aren’t fast.
The year is going hard and fast, right out of the gate. Multiple RFPs and new customers. New bits of business left and right. And lets not forget the support side … this is using up lots of time as well. Sales hire is almost done … not to offload, but to augment. Need to … Read moreBeen busy … as usual
