Type 1 Storage - HPE 3PAR InServ storage array

Following an extensive research and tender process, the HPE 3PAR InServ storage system has been selected to provide our Type 1 storage. This is an enterprise-class storage system engineered for excellent performance and reliability.

It has been selected in the first instance to provide a storage facility for the ongoing virtualisation of the majority of the University's servers. Server virtualisation is a specialised process which requires a very high performance storage system. The InServ is the best choice for this, as 3PAR have included several capabilities specifically designed to integrate with the VMWare virtualisation software to simplify the process of server migration and management.

More detail on the 3PAR system and its implementation within the Storage Area Network Service is available here.

Type 2 Storage - HPE Nimble storage array

The HPE Nimble storage unit was selected to provide our Type 2 storage. These are excellent high density storage units designed to provide large amounts of storage space without the premium price of a performance SAN infrastructure.

They have been selected to provide a storage facility for applications such as departmental file stores, and other uses where multiple terabytes are required without the need for the speed of the performance SAN environment. Despite this, the units have several capabilities which mark them out from the usual range mid-price disk arrays. Backed by the option of dual fabric connection for connected servers, they will provide many of the normal capabilities of performance SAN storage at a lower cost.

More detail on the Nimble systems and their implementation within the Storage Area Network Service is available here.


SAN storage at Warwick is connected via a dual redundant storage network. Hosts accessing the the Type 1 and Type 2 storage infrastructures will be connected to the storage network which will provide connection points for host servers and SAN storage in the three current SAN locations on campus.

It is proposed that the configuration of the storage network will be changed to take advantage of forthcoming enhancements and changes to the University data centre facilities.


Server virtualisation brings a new set of challenges for the storage administrator. The amount of storage used, and the way it is used is completely different from (and much more demanding than) a standard server host. Additionally, the advent of storage virtualisation means that a SAN can be much more flexible with the way the storage is presented to any host server. Thin provisioning, volume copies, data migration - all these are possible with a layer of virtualisation software between the storage hardware and the host servers.
