as configured above is $1,135.00. For nine of them the total would be $10,215. Now on to our virtual hosts. A DL380 G5 with two quad-core processors should be sufficient to handle eight virtual machines. A general rule of thumb in virtualization when computing the number of single vCPU VMs per single processor core is 4:1, so...

of the number of VMs running on a host. When calculating with a virtualization ratio of four VMs per core and dual quad-core CPUs per host, it is possible to run 32 VMs per host.
To virtualize 200 VMs, you would need seven hosts with dual quad-core CPUs. In this scenario, you would need a total of 14 Datacenter CPU licenses. At... More... May 27, 2009

systems can your hardware handle? How can you compare the performance of a dual-core server running at 3.2 GHz with a quad-core server running at 2 GHz? When the storage components of your guest OSes migrate from the old Fibre Channel (FC) storage system, to the new iSCSI storage system, how does the move affect performance...

supports Fault Tolerance, but the i3 series does not. So my decision came down to the 3430 and 3440 processors. Both are quad-core processors, but the 3440 supports hyperthreading, so it will appear as eight logical CPUs to my host. Also, the 3440 was slightly faster at 2.53 GHz, compared to the 3430, which runs at 2.40 GHz.
The 3440... More... Jun 8, 2010

a caveat: An installation message claims ESXi 4.1 requires at least 5 GB of memory -- so you need at least an 8 GB flash drive.
The core components of ESXi 4.1 take up less than 1 GB, however. So do you really need an additional 4 GB? Technically, yes, but you can circumvent this requirement and install ESXi 4.1 on a 1 GB flash drive. The... More... Nov 4, 2010
