Hey, I am currently considering a two machine Xen setup based on AMD Opterons, more precisely Dell R515s or R415s with dual Opteron 4274HE. Does anyone has some Xen setup(s) running on top of Opterons 4274HE, Opteron 4200 or Dell R515 machines and is willing to share some experience? In particular, I am interested in using Debian squeeze (Xen 4.0.1, Linux 2.6.32) for dom0 and most domUs. Any issues w...

...d anything in the Gluster documentation -- all the tuning info I've found seems geared toward Gluster 2.x. For some background, our compute cluster has 64 compute nodes. The gluster storage pool has 10 Dell PowerEdge R515 servers, each with 12 x 2 TB disks. We have another 16 Dell PowerEdge R515s used as Lustre storage servers. The compute and storage nodes are all connected via QDR Infiniband. Both Gluster and Lustre are set to use RDMA over Infiniband. We are using OFED version 1.5.2-20101219, Gluster 3.2.2 and CentOS 5.5 on both the compute and storage nodes. Oddly, it seems like th...

Meanwhile, I got myself a two machine test setup for evaluation. 2 machines: - 1x Opteron 4274HE (8C) - 32GB...
