3WARE 9550 LINUX DRIVER DOWNLOAD

Also for read look at blockdev --help. Device name unknown PCI: The other two settings should still be available. Archttp is statically linked so it will run in virtually all circumstances. If the performance problem is gone, then it is definitely the controller. Tested with Linux 3. They will profit off your hard work.

I hope to have it finished this week. Write cache can be enabled by running: I got a dual Xeon 3. Enabling write-cache is supposed to make the disks faster. Note down the exact size in blocks.

LXer: Horrible 3ware RAID performance: Linux

Here is a screenshot to see how it looks: I'll write up an article about my benchmark, put it up and e-mail you. It works fine with and cards, as well as with the w3are.

As far as I know the cache cannot count in this case because the write is a long linear one. Moreover, it show rebuild status in percent when the array is rebuilding and it's easily parsable because 3Ware filled the not relevant columns with a dash instead of leting them empty.

If you got redundant power supplies, don't worry too much. English is not my mother tongue and I may have garbled something. JBOD is about as fast as single disk.

I hope it is of some use! It also handles failure detection and report it by mail and syslog. Bit of a late response, but I've finally finished my benchmark article. Have you verified that it is actually the RAID card causing the slowdown? This may require a fsck or similar during the next boot. Then again, I'm writing much more than will ever fit in cache or in RAM when doing these tests.

3Ware Eskalad series

It works fine and doesn't rely on insane dependencies like java, tomcat or something else. Just create one partition that's slightly smaller than the actual drive size, e. I'm writing an article about my benchmark. RAID different brand drives together.

Linux and Hardware RAID: an administrator's summary

Archttp is statically linked so it will run in virtually all circumstances. Keep an eye out for it.

Latest Discussions Add to the list: Software RAID gives you a lot more flexibility, since it is not limited to RAID-ing entire disks, but works at the block level, so you can set up individual partitions. The CPU cooling is dependent on the case being closed.

No opensource tools for 3Ware cards currently exist. But I'm using LVM anyway. Download in other formats: Supported Supported by Linux kernel?

Powered by Trac 1. There 3waare Debian packages of both tools available from http: Not likely, but possible.
