Ohio Supercomputer Center Mass Storage Environment
The OSC
Mass Storage Environment (MSE) consists of servers, data storage
systems, and networks providing a number of storage services to OSC
HPC systems. The current configuration consists of:
- Two Cisco MDS9509 Fibre Channel switches with Fibre Channel and iSCSI blades.
- Four IBM FastT-900 storage servers, each with:
- Two independent controllers with two Fibre Channel links each.
- 16 TB (raw capacity) of Fibre Channel disks.
- Twenty IBM FastT-600 storage servers, each with:
- Two independent controllers with one Fibre Channel link each.
- 20 TB (raw capacity) of Serial ATA disks.
- One IBM 3584 tape robot:
- Four Fibre Channel links.
- Four LTO tape drives.
- 80 TB (raw capacity) of LTO tapes.
- Twenty-six IBM x345 servers, each with:
- Four gigabytes of RAM.
- Two, 2.6 GHz Intel P4 Xeon processors, each with 512kB of secondary cache.
- Two Fibre Channel interfaces.
- Two Gigabit Ethernet interfaces.
- One Infiniband 10Gb interface (in sixteen of the servers)
Home Directory Service
The MSE provides common home directories for users across most
OSC HPC
systems, including the P4 Cluster and Itanium-2
Cluster. The current capacity of the home directories is approximately 100 TB for all users and should be used for long term storage. A 112 TB Parallel Virtual File System (PVFS) is provided as work space for running jobs.
Note: To transfer files to/from OSC systems, use scp
or sftp between your machine and any of
the HPC machines. Since home directories are shared across all
systems, you can use any machine to transfer files to your directory
structure.
Parallel File System Service
The MSE provides a parallel file system to the cluster systems
for
use as high-performance shared temporary space, using PVFS2. This
storage can be
accessed from the P4 Cluster and the Itanium-2 Cluster. The current
capacity of the parallel file system is 112 TB
Backup Service
Regular backups are made on the MSE of all user home
directories, as well as
critical system files. For user files, monthly full backups and daily
incremental backups are kept, as well as a daily snapshot of the
current home directory file systems. The /tmp file system and the PVFS file system (/pvfs) are not backed up.
