Lead Senior Sun/Emc/Veritas/Solaris Infrastructure Design Engineer
Mail.Com
Engineered, built and administered the EMC-based Storage Area Network on which Mail.COM hosted its critical businesses: consumer, partner ISP, and business-to-business messaging (for example: Mail.com, Email.com, Iwon.com, CNN.com etc.). The design consisted of four EMC Symmetrix 3930s, two 3830s, three EMC dual director Connectrix Fibre Channel Switches, four EMC Celerra File Servers, and a dozen 28CPU Sun UEx500 Enterprise Servers. Additional components include software components such as EMC PowerPath, ECFM Connectrix Manager, Volume Logix, ECC SymCLI & OSM Manager, Veritas Volume Manager (VxVM), Veritas FileSystem (VxFS), etc.On the SAN side of the design, considerations such as redundancy and resiliency were made possible through multiple active (Power) Paths across different Fibre Channel switches, JNI HBA boards across different Sun I/O boards, VxFS for quick filesystem recovery, and VxVM mirrored O/S and SWAP volumes. High availability considerations were accomplished through the configuration of an additional UE6500 with visibility to the entire SAN storage pool via Fibre Channel zoning and Volume Logix HBA to FA hypervolume authentication. In this configuration, the UE6500 can assume the compute task of any of the other N UExx00 class Sun servers through sd.conf management, and through the VxVM diskgroup import/deport mechanism. ECC SymCLI TimeFinder and BCV’s are also configured for 3rd mirror based data backup, snapshots etc.Based on Sun’s Jumpstart model, engineered a platform for jumpstarting machines on Mail.COM’s global networks, without the need to configure jumpstart or even boot servers on remote segments. Traditional jumpstart environments minimally require a boot server on each client network segment. A result of this Light Weight Jumpstart Server design is that network segments no longer require (and are prohibited from having) their own boot, configuration, and install servers.Complete detail here: http://www.ComputingArchitects.Com
