Dell Poweredge 12G Server Memory Configuration Tool
Marien left a comment in my blog, in which he pointed out a very useful tool for correctly selecting Dell Poweredge 12G server memory configuration.
For me, highest speed (now it’s in 1600Mhz) is always my first choice, sometimes, I would rather trace off less total memory for the speed as memory is the top competing resource among many VMs on the same host. Therefore, you do need to know DPC (Dimm per Channel) inside out.
Memory power consumption is the 2nd most important factor, so I always select Low Voltage (LV) 1.35 Volts as they do save quite a bit when you add up all the sticks.
Finally, 16GB is becoming the norm these days, a 288GB ESX host is no longer a dream especially when the good news of vSphere 5.1 removed the vTax limitation.
PS. Another thing I learn about the new R720 is the latest 12G server uses at least 1/4 less power than previous 11G R710 which is a great news!
