Purchase: Storage & Backup

The backup service is described here and the managed storage service is described here

Managed Storage

Storage and backup can be purchased in advance of usage and will be charged at the cost of expansion required. The cost takes into account all the required infrastructure including Servers, Software, Storage and Network Switches, Storage Controllers and UPS systems.

There are 5 performance levels available for purchase depending on the application. We would recommend Alloy performance for most applications.

  • Alloy : 15,000RPM Disk in RAID1 + 7,200RPM Disk in RAID6 : 100ukp per 1TB per quarter including backup
  • Platinum : Solid State Disk + 15,000RPM Disk in RAID5 tiered and managed by IBM SVC: 75ukp per 100GB per quarter
  • Bronze : 7,200RPM Disk in RAID5 : 60ukp per 100 GB per year including backup - Deprecated in favour of Alloy storage
  • Silver : 10,000RPM Disk in RAID5: 200ukp per 100 GB per year including backup - Deprecated in favour of Alloy storage
  • Gold : 15,000RPM Disk in RAID1: 250ukp per 100 GB per year including backup - Deprecated in favour of Platinum storage

Alloy disk is most commonly used for Lab Shares particularly for volumes of 1TB and above. Bronze disk is most commonly used for Cluster users homes and shares. Silver is suited for a high number of users on a relatively small total disk volume or database servers. Gold is suited for applications such as high performance database servers. Platinum storage is used to provision VMs and provides advanced Storage Virtualisation features using IBM Storage Virtualisation Controller including multi site replication.

Our storage advisors will be happy to help you select disk with appropriate performance for your application.

Workstation and Virtual Machine Backup

Workstation and Virtual Machine backup is charged at £100 per annum with data use above 50GB charged at £0.25 per GB per annum.

The fixed cost, £100, represents the licensing and management cost with a reasonable amount of data.

The scaling cost, £0.25 covers the additional tape media and library slots required.
