Seawolf

Seawolf is a Sun Fire 6800 which acts as the long term storage server for ARSC computational resources.

Specifications

The system is configured as follows:

8 CPUs
900MHz Clock frequency
16 GB Memory
20 TB of Local Disk Capacity
4- STK T9940B Fibre Channel tape drives
6- STK T10000A Fibre Channel tape drives

Description

Seawolf provides permanent mass storage for user data at ARSC. The system is connected to tape drives in the STK SL8500 automated tape library. Together with the library, Seawolf has enormous capacity, theoretically more than seven petabytes (7000 TB). Users have a small, quota-limited home directory and an 'archive' directory. Other file systems are available for special purpose applications and groups.

The Sun hardware is configured in a fault-tolerant configuration. The disks are either mirrored or RAID with multiple paths, to ensure that failure of any single disk or control/data path is unlikely to interrupt access to data. The large number of accessible tape drives ensures that a failure of any one drive will not prevent access to the data. Finally, most of the network paths are dual-path to the network routers and switches. Both network paths are active, thus increasing the aggregate bandwidth to/from the systems.
