HP D530 SFF: cpu upgrade & fan noise
So I was upgrading some older equipment, these d530's came w/ a 2.8ghz, 533mhz bus pIV cpu, well I upgraded a couple of them to a 3.2ghz 800mhz cpu. Dispite putting new heat sink compound, blowing out the CPU fan, and upgrading the bios, the machines would often sound like a Boeing 747 during times of high cpu usage. I found several posts on the subject, no real answers, most suggestions were stuff I already tried. What I did stumble on, was that in the bios there is a setting for changing the cpu fan idle speed. I moved it up to 4, the highest level. This does make the machine more noisey, because the fan is spinning faster all the time, however it doesn't kick into hyper-speed nearly as often.
Backup Exec 3600
This is an interesting approach to backing up. It is an all-in-one self contained APPLIANCE.
-1U server (looks a lot like a Super Micro)
-customized W2k8 R2 Storage server
-16gb of ram
-2.4ghz quad core
-40gb SSD for O/S
-2tb sata drives *4, RAID 5 (5.5tb raw, 50tb deduped)
-Full install of Backup Exec 2010 R3 with license for ALL agents.
The MSRP of $25k is steep but when you consider what it would cost w/ other dedupe options to get to 50tb of disk storag, the BE 3600 looks pretty cheap. It includes all agents, it doesn't matter if one is backing up one Exchange server or twenty of them, no additional costs!
Administration is done via a web portal, but uses the same BE 2010 interface. For all practicle purposes it looks just like a BE2010 media server. All updates (including the Window OS) come from Symantec Live Update.
It has some sort comings, such as no tape drive, iSCSI, or fiber channel support. Replications need to happen to another BE server or USB (yuck!). Rumor is those options are being looked into.
Dell work stations interleave memory!
Many Dell workstations will interleave their memory when identical ram modules are installed. So that means if you have a choice between installing four 1gb modules or two 2gb modules, go w/ the four 1gb's, you will get more though put.
