Why this site?

The intention of this site is to share my SAN and Unix related knowledge with everyone. I’ve been fortunate enough to gain a lot of technical skills via reading, working with highly skilled colleagues, googling, and lastly working (and sometimes burning my hands) on live critical production systems.

Here I’ve put together information on SAN (HDS/EMC/Netapp/HP EVA/Cisco/Brocade), Unix (Solaris/Linux/Veritas), and Scripting (shell/perl). Hopefully you will find them useful. Any suggestions/constructive criticisms are welcome.

These spare chunklets are distributed across all drives. Raid functionality is implemented at Logical disks (LD) level. Depending upon RAID level specified, LDs are formed by striping […]
