Oxford's Tier 2 Upgrade is joining the grid.

The 22 new worker nodes are starting to come on line now.
They are running SL4 32bit mode for now. They will provide an additional 431 K Spec Int 2000.

A second ce has been setup to serve the SL4 WN's. We had some trouble with the BDII being on the original ce so have split that function off onto a new node (Well actually a VM ).

The upgrade also includes 4 heads nodes with dual PSUs, and mirrored systems disks, which can be used for service functions or as worker nodes. All the head nodes and disk servers are protected by UPS.

The 11 storage servers (9TB usable each) will be brought on line over the next week.

The two new (Viglen supplied) racks are on the right hand side, with the older Dell kit on the left.

Oxford Local Computer Room Goes Live

The local computer room was completed last Friday. All power is ready under each of the 21 rack positions. Each rack position has 4 CAT6 cables connected to the networking rack which can be seen. Other things completed were; ceiling lights, painting, smoke detection system, and door fitting.

On Monday 10th two existing compute racks were installed and two empty racks for the cluster upgrade arrived. A rack full of worker nodes for the existing grid cluster can be seen and is up and running.

Today the servers arrived from Viglen and installation has commenced.
