Intel SRCS16 SATA Raid controller
Zdravim,
mate niekto skusenosti s kontrolerom Intel SRCS16 SATA RAID? Jedna sa mi hlavne o benchmarky pri konfiguracii s RAID 5 a 4x400GB. Pouzity driver je megaraid2. (Radic obsahuje LSI MegaRAID chipset.)

Neda sa SATA nejako nastavit/tuningovat vo Fedora 4 ? Ako si mozeme porovnat vykonnost radicov ?/dev/sda + /dev/sdbNON-RAID SATA HD: Maxtor 6L080M0 Radic: Onboard Intel 82801FR/FRW (ICH6R/ICH6RW) SATA Controller (rev 03)/dev/sdcRAID-5 SATA HD: WD Caviar SATA WD2500SD-01KCC0 Radic: Intel SRCS28Xhdparm -tT /dev/sda /dev/sdb /dev/sdc/dev/sda: Timing cached reads: 3532 MB in 2.00 seconds = 1765.89 MB/sec HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device Timing buffered disk reads: 118 MB in 3.00 seconds = 39.28 MB/sec HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device /dev/sdb: Timing cached reads: 3756 MB in 2.00 seconds = 1877.88 MB/sec HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device Timing buffered disk reads: 136 MB in 3.01 seconds = 45.21 MB/sec HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device /dev/sdc: Timing cached reads: 3680 MB in 2.00 seconds = 1839.89 MB/sec Timing buffered disk reads: 90 MB in 3.10 seconds = 28.99 MB/sechdparm -tT /dev/sda /dev/sdb /dev/sdc/dev/sda: Timing cached reads: 3632 MB in 2.00 seconds = 1815.89 MB/sec HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device Timing buffered disk reads: 94 MB in 3.24 seconds = 29.01 MB/sec HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device /dev/sdb: Timing cached reads: 3608 MB in 2.00 seconds = 1803.89 MB/sec HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device Timing buffered disk reads: 96 MB in 3.82 seconds = 25.13 MB/sec HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device /dev/sdc: Timing cached reads: 3676 MB in 2.00 seconds = 1837.89 MB/sec Timing buffered disk reads: 102 MB in 3.44 seconds = 29.61 MB/sechdparm -tT /dev/sda /dev/sdb /dev/sdc/dev/sda: Timing cached reads: 3628 MB in 2.00 seconds = 1813.89 MB/sec HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device Timing buffered disk reads: 106 MB in 3.62 seconds = 29.28 MB/sec HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device /dev/sdb: Timing cached reads: 3752 MB in 2.00 seconds = 1875.88 MB/sec HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device Timing buffered disk reads: 188 MB in 3.03 seconds = 62.00 MB/sec HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device /dev/sdc: Timing cached reads: 3532 MB in 2.00 seconds = 1765.89 MB/sec Timing buffered disk reads: 316 MB in 3.08 seconds = 102.72 MB/sechdparmdokaze poskytnut nejake smerodajne udaje o vykonosti. V pocitaci je iba jedna dodatocna PCI karta a to je ten RAID radic, tak neviem ci je pretazena PCI zbernica - ako to zistim ?
