San storage is provided for servers with hba connectivity via a brocade dual fabric to virtualised IBM storage, giving SAS, SATA and FC depending on performance needs.

This provides secure connectivity between the server and storage independent of the Ethernet network.

NFS exports from IBM Nseries can also be provided with the benefits of snapshots.

 

Available Features

Raid 5 and 6 resilience with hot spare coverage is provided depending on the performance/cost requirements.

 

Remote replication
Data served by the IBM Nseries can be replicated to a remote site for extra resilience, (The storage cost is doubled in this scenario).

 

Supported operating systems

  • Windows server 2003
  • Windows server 2008 and R2
  • RHEL 5.x
  • SUSE Linux Enterprise 

 

Pricing

Storage Type Included Features Yearly Cost/TB 5 Yearly Cost/TB
FC Raid 5   £5,515
SATA Raid 6   £840
Nseries Raid, snapshots, NFS, CIFS   £1,260

 

Storage infrastructure and backup

The SAN infrastructure is based on a Brocade resilient fabric, using IBM enterprise storage which is virtualised by IBM SVC giving increased performance via caching and more flexibility for storage allocation.

Files are served by IBM Nseries gateways giving CIFS and NFS access to files.

GPFS storage is also provided for Escience  HPC use.

Production servers providing services including the portal and email use SAN backend storage via HBA connections to the fabric.

Data is backed up using IBM Tivoli Storage Manager (TSM) which writes to IBM 3584 robotic tape libraries. Data is vaulted between libraries in physically separate data centres to provide off site disaster recovery.

All hardware is hosted in two data centres with UPS power protection and air conditioning.

All services are monitored by our operations team, who routinely replace failed components with no service disruption due to in built resilience.
