similar to: hdparm equivalent for SATA

I've got a brand new .5U P4 system running several (I think) Seagate 80gig SATA drives. I tried to copy data from the first drive (sda) to the second drive (sdc) and was only getting about 1.7megs/sec. So I figured DMA was off. And this is what happened when I typed "hdparm -d1 /dev/hdc": /dev/hdc: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted

Is it possible to set up a single disk raid (kind of redundant to call a single disk an array) but I've got a single SATA drive in the machine not doing anything. It's a 10k maxtor 74G drive, and what I really want is just to backup two home partitions. I can always reinstall the OS, but the data can't be recovered that easily. The mobo supports raid-0,1 and jbod. Suggestions? --

Hi Gang, I recently rented a server at a datacenter with Centos 5.7 X64, Q9550 Processor, 8GB Ram, and dual 250GB SATA HDs (with 16mb cache). They had loaded it with KVM, and installed a 30-day trial of Virtualizor as the front-end for KVM. I was so impressed with how fasts the guests ran that I want to build a few of these machines for myself. I just installed one: same Q9550 processor, 4GB

we just purchase new I/O card and like to check I/O performance. for sequence I/O performance test we can use "hdparm -t /dev/xxx" bur for random I/O performance test which Linux command I can use? ** our environment does NOT allow install third party software.. Thanks

I need to disable the spin-down on an external USB drive because it spins down spontaneously while in use. The drive forgets the spindown-disable state across power outage so I need to reissue the hdparm command with each boot or hotplug. Where should I put the hdparm command to do this?

Can someone please explain what's wrong here. And how to solve it. I run CentOS-4.1 MSI K8N Neo Platinum Athlon 3000 Seagate Barracuda 7200.7 S-ATA disc [root at amd64 kai]# /sbin/hdparm -tT /dev/sda /dev/sda: Timing cached reads: 2808 MB in 2.00 seconds = 1402.81 MB/sec HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device Timing buffered disk reads:

I believe I've posted before about one of the speed issues we were having, of backups taking many, many hours that should *not* take that long. My manager and I finally nailed it down to the h/d itself. Identical boxes, and he tried a backup of one system which took under two hours, while the same regular one rand nearly six. I'd been googling on and off for weeks, and this morning, ran

At the present moment, my guest is running inside qemu and host is kvm intel, running Ubuntu 14.04, kernel is 4.3.0 stable. From within the guest, when I run "hdparm -i /dev/sdb" on the guest, I get: HDIO_GET_IDENTITY failed: Invalid argument as the error,but on the host, I will get the full harddisk/SSD info. Can I know how to resolve this so that the output is the same for both

Hello all, I'm creating a site where people can share their benchmarks. If you are interested, the site is at (I just started on it so it has the stock graphics and color scheme still): www.dcsnow.com/mambo I would like some thoughts on what would be a good way to standardize the testing so the results are more comparable. Is Bonnie+ a good program for hard drive speed testing? Is there

What is a good transfer rate to expect when writing from Windows XP/Vista to a samba network share in the following situation? * New client. Intel Core 2 Duo 6600 with 4GB memory, and Intel gigabit NIC. * New server. HP XW8400 with (currently) a single 5335 Xeon with 4GB memory, and integrated Intel gigabit. Running samba 3.0.25b, as included with CentOS (RHEL). * Netgear GS116 (gigabit)

I have two identical servers. The only difference is that the first one has Maxtor 250G drives and the second one has Seagate 320G drives. OS: CentOS-4.4 (fully patched) CPU: dual Opteron 280 Memory: 16GB Raid card: 3ware 9550Sx-8LP Raid volume: 4-disk Raid 5 with NCQ and Write Cache enabled On the first server I have decent performance. Nothing spectacular, but good enough. The second one

I can't seem to get the read and write performance better than approximately 40MB/s on an ext2 file system. IMO, this is horrible performance for a 6-drive, hardware RAID 5 array. Please have a look at what I'm doing and let me know if anybody has any suggestions on how to improve the performance...

Tony?s performance sounds significantly sub par from my experience. I did some testing with gluster 3.12 and Ovirt 3.9, on my running production cluster when I enabled the glfsapi, even my pre numbers are significantly better than what Tony is reporting: ???????????????????

Hi. I have 2 PC's connected with 1GBit NIC's. When I transfer a file from my File-Server(Redhat9.0, 256 SD-RAM, 300MHz PII, RTL8169 NIC, 2x Western Digital WD200JB RAID 0) to my Windows-PC(AMD Athlon XP 1800+, 1024 MB DDR-RAM, WINXP PRO, RTL8169 NIC, 2x Western Digital WD080JB RAID 0) with Samba, i get Speeds around 8-9MB/sec. I think this is too low for an GBit Network, so i tested the

I'm just wondering what folks are using to benchmark/tune large arrays these days. I've always used bonnie with file sizes 2-3 times physical RAM. Maybe there's a better way? Cheers,
