"The IBM DS 8300 Data Storage Systems are multi million dollars flexible high availability and performance SAN machines.
"But you may left much of such performance and availability behind if you do not configure then correctly for Debian GNU / Linux.
"The IBM DS architecture was born for mainframe use. So you need to understand some different concepts / naming from the Debian GNU / Linux regular ones.
"The IBM DS 8300 hardware and software (it is a multi cpu Power AIX machine) is optimized for highly parallel I/O requests.
"The IBM DS 8300 hardware could be "logically partitioned" (LPAR) in order to guarantee quality service levels (space, latency, transfer speed) and LPARs could be grouped into Storage Facility Images (SFI) for more availability. It is like a QoS, reserving disks, interfaces, cpus, ram for some hosts."
