Yes, I've worked with several that can do that. The interesting thing with disk arrays now is the controller heads are becoming the bottleneck.
You used to have many many shelves of SAS drives per controller pair, now the SSDs are so fast that the CPUs are saturated and you have to scale out, not up.
- hinkley 9y agoIf I can't (reliably) handle 100GBps coming from the RAID array it sounds like I'm not going to be able to handle 400GBps coming in from the NIC. So these really are just for interconnects for the time being, until server hardware gets faster.
- buzer 9y agoThere are some applications which can handle 100Gbps and potentially higher speeds on servers. Usually they require using DPDK or similar frameworks with userland TCP stack (and thus are usually pretty specialized), but at least Netflix has managed to serve 90+Gbps of TLS traffic using "default" FreeBSD TCP stack (https://medium.com/netflix-techblog/serving-100-gbps-from-an-open-connect-appliance-cdb51dda3b99 https://medium.com/netflix-techblog/serving-100-gbps-from-an...).
