Compute Servers

What are they?

The management server has this specification

  • Dual Eight Core Intel Xeon E5-2620v4 Processors
  • 128GB DDR4-2400 ECC Registered Memory
  • 5x 2TB SATA Hard Disk Drives
  • Intel X540-T2 Dual Port 10GBase-T Ethernet Adaptor

The eight compute servers each have this specification

  • Dual Ten Core Intel Xeon E5-2630v4 Processors
  • 128GB DDR4-2400 ECC Registered Memory
  • 2x 1TB SATA Hard Disk Drives
  • Onboard Intel X540 Dual Port 10GBase-T

The Operating System used on all of these servers is CentOS 7. The servers are managed using a combination of the Bright Cluster Manager 7 and Kubernetes.

Where are they?

All of the servers are installed in the University House Data Centre at the University of Warwick.

What are they used for?

WISB researcher’s computational tasks can be deployed on these servers using the Slurm Workload Manager. More complex services can be deployed using the Kubernetes container orchestration platform.

Storage Servers

What are they?

The storage server and the backup server have the following specification

  • Dual Eight Core Intel Xeon E5-2620v4 Processors
  • 256GB DDR4-2400 ECC Registered Memory
  • 2x Intel DC S3500 Series 120GB SSDs
  • 2x LSI9200-8E SAS Host Bus Adapters
  • Intel X540-T2 Dual Port 10GBase-T Ethernet Adapter
  • 60 Bay SAS JBOD with Redundant Power and Dual SAS Controllers
  • 18x 4TB SAS Hard Disk Drives

The Operating System used on these storage servers is FreeBSD 10. The Z File System (ZFS) is used to store the data. The file system is constructed using a pool containing two nine-disk RAIDZ2 virtual devices. This provides redundancy in the case of disk failure. Regular snapshots of the data are created and transferred to the backup storage server.

Where are they?

The production server is installed in the University House Data Centre. The backup server is installed in a different location, the Argent Court Data Centre also at the University of Warwick.

What are they used for?

Data originating from two primary sources is stored on these servers

  • Equipment in the WISB Research Technology Facility.
  • Computational work output.

After the initial installation there is 47.96 TiB of space available. As it becomes necessary, new hard disk drives will be added to increase the space available to a maximum of approximately 200 TiB.

The storage server is generally accessible on RTF equipment computers through mapped network drives.
