Opterons and Nelahem (55xx and later) Xeons have a NUMA architecture – each socket has its own memory bus and there is a link between the sockets. This link is called Hypertransport on Opteron systems and Quickpath on Xeons. The G5 predates Nelahem and still uses the older Front Side Bus, which is not a … Read more
While the other answer here beings up some points, your specific issues are due to platform limitations and OS configuration: You’re throughput-limited by the use of consumer SATA SSDs on an HP Smart Array P410 RAID controller. SATA disks run at 3.0Gbps (3G) on these controllers rather than 6.0Gbps (6G). So that’s a barrier that … Read more
My favorite example: This can be run from the shell or within the tool. hpacucli ctrl all show config (use hpacucli.exe for Windows) Or hpacucli ctrl all show config detail But, if you have the HP Management Agents installed anyway, you should have realtime monitoring of RAID status pushing back to email alerts or an … Read more
Storage performance can get a bit complex, but the underlying statement is true. 10k or 15k have similar performance, for the most part. If you put them side by side doing the type of work that disks are worst at (random small-block IO), you will measure a difference, but the reality is that with most … Read more
SATA2 disks should be compatible with the Smart Array P400i that comes with your server (or any other SAS controller, for the matter), although probably not with stellar performance as others have noted. But keep in mind that not all SATA disks are suitable for use with RAID because of the infamous Time-Limited Error Recovery … Read more
The HP Smart Array P410 is a fine controller, but you will get poor performance out of it if you don’t have the battery-backed or flash-backed cache units installed. The cache makes a tremendous difference in that writes are buffered by the cache memory before being committed to disk. You get the write confirmation to … Read more
I have experienced this exact same issue with similar Pentium 4 computers from HP. Within about 9 months we reapplied thermal compound to nearly all 80 or so of these PC’s. They were all about 4 years old at the time. After the 5th pc or so, our purchasing department leaned on the hp sales … Read more
The key to entering the ILO BIOS setup utility on current-firmware G6 or G7 ProLiants is to follow the prompts very carefully and get the timing just right… Note: You can also configure the ILO directly from the HP SmartStart DVD included with the system. Also, there’s a way to script the ILO and BIOS … Read more
Assuming you’re on a recent firmware revision for the DL320 G6 server. You’re going to have to pay close attention to the POST messages in order to catch the RAID controller’s ORCA utility prompt. The “Sea of Sensors” POST routine takes awhile from the first screen prompt (on a warm-boot) to step through RAM checks … Read more
Yes, you can run this server happily in under 2.5 Amps total… I can show you real-life utilization for that server platform/model. Watts = Amps x Volts Your power regulator and power supply efficiency mode settings will have an impact, but the example I give below is from one of my co-located ProLiant DL360 G7 … Read more
