Cisco's fifth UCS server generation surfaces Five new Cisco UCS servers have come to light, courtesy of Storage Review, which temporarily withdrew its story for some reason. Tsk tsk. Early signs are that Cisco appears to be cutting its blade server product line count. Cisco has made no formal announcement yet but we're expecting one in a few hours. All these M5 …
Memory bank totals have stayed the same. You used to have 3 banks per channel and four channels per CPU. Now it's only two banks but six channels, so the total of 12 stays the same.
It was really not funny to populate all three banks on a channel because memory clock speed would drop by three clicks (2400 down to 1666MHz). Cisco UCS is/was the only platform which would only drop by one click (2400 to 2133) when fully populated, hence their popularity in high density and high performance shops.
Alas, now the playing field is level again in regards to RAM. We shall see what the big differentiators will be. I look forward to many presentations about power and cooling savings!
