I have “one rack” in my data center with 120tb of storage capacity and the servers to carve it all up.
To be fair, 120 TB isn’t that much storage in today’s terms. That’s two 25-disk DAS trays full of 4 TB SAS disks in a RAID5.
Cisco’s UCS offerings put massive amounts of networking and computing into a 10RU chassis that can run circles around HP’s latest BladeSystems. And this is coming from an HP fanboy!
