I'm on a N40L and found that FDE taxed the CPU too much underneath a RAID 6 array to be useful. I've heard that the more recent models are CPU upgradable to CPUs with AES-NI. What sort of FDE R/W speeds are you seeing?
- pedrocr 13y agoI don't use encryption. I just checked my munin graphs and the CPU sits ~90% idle, and this is on a N36L, I guess the newer N56L would be better. It seems the newer generation has moved to Intel but still without AES-NI: https://ssl.www8.hp.com/us/en/products/proliant-servers/product-detail.html?oid=5366896#!tab=specs https://ssl.www8.hp.com/us/en/products/proliant-servers/prod... It's not clear from what I've read if you can swap the processor out. Why do you run FDE? How do you boot it?
- joshka 13y agoI don't run FDE, because it's too slow to do so (by around 1 order of magnitude IIRC). See http://b3n.org/installed-xeon-e3-1230v2-in-gen8-hp-microserver/ http://b3n.org/installed-xeon-e3-1230v2-in-gen8-hp-microserv... for info on how to do the chip upgrades in the current model.
- pedrocr 13y agoLooks straightforward. Why would you want FDE in this context?
