Ultra 5 disk performance [Was: More storage for my Ultra10]
Hi,
having red Andrews mail I tried some disk IO on my Sun Ultra 5
(CPU: 333MHz, RAM: 512MB, kernel: 2.6.12.4)
The system was equipped with its original IDE disk and a newer 200GB
one (btw: all 200gigs are available with newer 2.6 kernels).
Additionally the system is equipped as follows
2) SCSI-system:
SymBios 53C876 controller, (~3 yrs. old) external 30GB SCSI disk
(ext3 FS)
3) USB-System:
NEC Corporation USB 2.0 controller, Trekstor USB 2.0 160 GB disk
(vfat FS)
4) Silicon Image, Serial ATA (Sil 3112) Controller, Maxtor 200G disk
(ext3 FS)
This is what I get when running hdparm -tT /...devpath
(I'll include the result of a bonnie++ at the end of the mail.)
1) IDE
/dev/hda1:
Timing O_DIRECT cached reads: 700 MB in 2.00 seconds = 349.70 MB/sec
Timing O_DIRECT disk reads: 38 MB in 3.09 seconds = 12.31 MB/sec
2) SCSI
/dev/sdb1:
Timing O_DIRECT cached reads: 672 MB in 2.01 seconds = 335.05 MB/sec
Timing O_DIRECT disk reads: 42 MB in 3.07 seconds = 13.66 MB/sec
3) USB
/dev/sdd1:
Timing O_DIRECT cached reads: 660 MB in 2.01 seconds = 328.74 MB/sec
Timing O_DIRECT disk reads: 28 MB in 3.03 seconds = 9.23 MB/sec
4) SATA
/dev/sdc1:
Timing O_DIRECT cached reads: 704 MB in 2.01 seconds = 350.48 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate
ioctl for d
evice
Timing O_DIRECT disk reads: 156 MB in 3.01 seconds = 51.82 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate
ioctl for d
evice
Regardless of the 'failed' messages for SATA, the disc seems to work
fine for me.
I'm not shure about their relevance ...
It's not a fair comparison due to older IDE and SCSI hardware, different
filesystem on USB et. cetera.
Nevertheless it may give You a hint. As I am the one who was really
unsuccessful with the selected USB cards I'd see SATA or SCSI as choice
for buying new disks.
BTW: I'd be really interested if someone has newer SCSI hardware
available for testing.
If money doesn't matter ... :-)
Cheers, Roger
