SR1520 is a 15 disk unit. It is 3U. It takes SATA disks. As a result, it can 
hold up to 11.25TB until SATA drives get bigger.

The configuration is basically put in disks and fire it up. You can then 
create raid sets and everything else you'd expect. You can do the config from 
a connected keyboard/monitor, serial terminal, or cec (something like telnet 
over ethernet). I personally use an Opengear serial terminal server for 

It runs Plan9 with no IP stack. I consider this a slight disadvantage in that 
it cannot produce SNMP traps. The only way to monitor it is to send udp 
syslog messages to a syslog receiver and grep info out of the collected logs. 
I think it would be much cooler if it ran a TCP/IP stack on its interfaces so 
that you could ssh in directly. A sufficiently clever hacker could probably 
pull it off considering that they use the rc shell as their command shell. If 
they had a TCP/IP stack, it would be able to send SNMP traps and even present 
an http interface.
