I need a SATA RAID PCI card that works well with CentOS and is fully supported. Mandatory features: - works with the drivers already in the kernel, no additional drivers - can do RAID 0, 1 and 5 - hotswap - allows to monitor the status of the array and of each individual drive via a script (ideally run from cron) - works with very large SATA drives Nice to have features but not mandatory: - small battery to keep the array alive until the write buffers are flushed after a power loss Anyone having positive experience with SATA RAID, please comment. -- Florin Andrei http://florin.myip.org/

Period. 9550/9590 will do everything you want. 9650 gets you RAID6, but I'm not sure the distro provided drivers have caught up yet. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
We just built a 6+ TB array using 10x750GB drives using a 3ware 9650SE-12ML on CentOS4. The 3ware cards are top notch and I am guessing you will be hearing that a lot from others on this list. Many of their models do have the ability to add a battery for the cache. 3ware has a tool to monitor the card called 3dm2. Nice web based tool that allows you to configure the card and see the status of the devices. What are you trying to build?

I'm another satisfied 3ware user. I'm up to about 25 systems with cards in them. tw_cli is very scriptable for monitoring (see my post from yesterday :)) On 3/20/07, Florin Andrei <florin at andrei.myip.org> wrote:> > I need a SATA RAID PCI card that works well with CentOS and is fully > supported.
