Hopefully I can get a little advice here about a few things. I appreciate the support I had a few weeks back regarding the PSU for these computers. First, I'll start with the specifications of the servers. We have 3 servers identical to the specs below.
Motherboard: SUPERMICRO MBD-H8DCL-IF-O ATX Server Motherboard Dual 1207-pin Socket C32 AMD SR5690 DDR3 1600/1333/1066 - Newegg.com
3 Hard drives: Western Digital VelociRaptor WD5000HHTZ - Newegg.com
Raid Card: HighPoint RocketRAID 640 Controller Card - Newegg.com
Two Heatsinks: Noctua NH-U9DO A3 AMD Opteron, 4 Dual Heat-pipe SSO Bearing Quiet CPU Cooler - Newegg.com
32GB of Ram: Kingston Server Memory Model KVR1333D3D4R9SK2/16G - Newegg.com
2 AMD Opteron 4280: AMD Opteron 4280 Valencia 2.8GHz 8MB L3 Cache Socket C32 95W 8-Core Server Processor OS4280WLU8KGGUWOF - Newegg.com[/QUOTE]
Case: Athena Power RM-4U4038B48 Black Server Case - Newegg.com
Power Supply: SeaSonic M12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 SLI Ready 80 PLUS BRONZE Certified Modular Active PFC Power Supply - Newegg.com
Now to some of my concerns. First, we're running RAID 5 with 3 WD VelociRaptors. Of course RAID 5 isn't for speed but it should offer improvements. BTW the RAID card we chose was a bad pick and may be the issue to both of our problems. On all 3 servers we average write speeds of about 175MB and read speeds of about 340MB. That's a decent improvement on read speeds but no gain in write speeds. (Factory specs are about 175MB Read & Write) Shouldn't the write speeds have gone up as well? Any ideas as to what might cause slower speeds?
The other issue we've had that has made the installation of software a major pain is the boot time. All 3 servers have about a 15 minute boot time. The BIOS & RAID card both post but after a black screen appears for about 10 minutes. The windows logo then appears but sits there for another 5 minutes before it boots. Once booted, it runs just fine. We're running Windows Server 2012 and all we can imagine is that it's a device driver that's not working right. All devices are accounted for in the device manager. We've gone as far as to pulling everything but the Mobo, RAM, CPU, Drives, and RAID card to see if it was one of the other cards but no luck. I've tried a countless # of searches to find an answer but nothing matches up. Any ideas?
