3ware now provides driver disk for CentOS. A couple of months ago, I had to add support for the 3ware 9550sx. The driver disk provided for CentOS 4.1 work perfectly. I now need to add support for the 3ware 9550sx for CentOS 4.3 x64. Although the driver disk is available, it doesn't seem to work. Anaconda just can't find the 3w-9xxx module. This is the same seutp as CentOS 4.1 (which works) so I...

Guys, I''m about to set up Xen on a dual Opteron server backed with SATA storage which is driven by a 3ware 9550SX controller. The problem is that as linux-2.6.12.6 has no support for this type of card by default, so I need to download & compile the driver the vendor provides. I did so (for the kernel 2.6.12.6-xen0) and generated an initrd image which gets loaded properly at bootime, but whenever the 3w-9x...

I'm getting a couple of systems that are arriving with the new 3ware 9550sx controller. Does anyone know when this will be natively supported by CentOS? Has anyone built an RPM of the driver/module for this new controller?

I run a decent amount of 3ware hardware, all under centos-4. There seems to be some sort of fundamental disagreement between ext3 and 3ware's hardware RAID5 mode that trashes write performance. As a representative example, one current setup is 2 9550SX-12 boards in hardware RAID5 mode (256KB stripe size) with a software RAID0 stripe on top (also 256KB chunks). bonnie++ results look like this: mount -t ext3 175 MB/s writes, 352 MB/s reads mount -t ext3 -o data=writeback 185 MB/s writes, 254 MB/s reads mount -t ext2 340 MB writes, 266 MB/s re...

From a buddy of mine that has spent a little time with the new cards. This was in response to my email asking about his impressions of them: It just came out in mid-September. There are a couple reasons I'm not thrilled with it: 1) no 8-port multilane version (only 12) 2) the 8-port non-multilane version is a kludge, connector-wise (a row of 3 double-stacked connectors along the

Dear list, I thought I'd just share my experiences with this 3Ware card, and see if anyone might have any suggestions. System: Supermicro H8DA8 with 2 x Opteron 250 2.4GHz and 4GB RAM installed. 9550SX-8LP hosting 4x Seagate ST3250820SV 250GB in a RAID 1 plus 2 hot spare config. The array is properly initialized, write cache is on, as is queueing (and supported by the drives). StoreSave set to Protection. OS is CentOS 4.5 i386, minimal install, default partitioning as suggested by the instal...

I just built up a server running CentOS 4.3, and trying to boot from a 3Ware 9550SX-16ML, 16 port card. This system has 9x500GB drives, AMD Opteron, Tyan K8SD mobo and 1 GB of ram. I downloaded the latest (9.3.0.4) driver from 3Ware, and after a couple of botched attempts, I got CentOS installed. In my two botched attempts, the problem was X hanging during the formatting of the dr...

I know there are a few 3Ware fans here and I was hoping to find some help. I just built a new server using a 3Ware 9550SX-4LP with four disks in raid 5. The array is fully initialized but I'm not getting the write performance I was hoping for -- only 40 to 45MB/Sec. 3Ware's site advertises 300MB/Sec writes using 8 disks on the PCI Express version of this card (the 9580 I think.) I'm guessing 4x PCI Exp...

Hi, Is it possible to create one raid volume of 3.3 TB (9550SX-8lp X WD5000YS - 8nos) and create a file system with ext3? (CentOs4.3 64bit) The maximum I am getting is 1.24tb and fdisk returns no more space available. But when I say fdisk /dev/sda it list full size of 3.3 TB. But I can not create partitions more than 1.24TB. Any idea? Thanks Rajeev...

I am trying to get a 9550SX to support a 1.5TB raid partition. I am unsure whether this is a driver problem, or an ext3 problem (as am getting some other wierdness detecting LUNs), but... fdisk recognizes the disk OK. I make a single extended partition with a single 1.5TB logical partition inside it. I then run mke2fs -j /d...

I have the latest kernel with the drivers for my 3ware 9550SX built in. Where can I find the tools and monitoring apps for this card? Are there rpms hiding somewhere, or do I need to build it from source? -- Bowie

Hi all. We just put a relative large server in operation (for our measures ;-) ), a 4x Dual Core / Intel with 16GB Ram and a 3ware 9550SX SATA-RAID with 4 drives. Operating system for the Dom0 is an up-to-date gentoo linux. Everything runs really fine, there are 4 Domu''s running, 1x gentoo and 2x debian and 1x Windows Server 2003. DomU''s are running blazing fast in normal work, no problems at all. Problems appe...

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 has about 1/3 the write speed. I can't find any difference between the systems. Both of them have the same stripe size, both h...

Greetings. I am in the process of installing 5.1 64 bit on a server. The server has 2 3ware cards: 9550SX 12 port, and a 8006 2 port, both SATA. I want the 8006 board to be /dev/sda, and the 9550 to be /dev/sdb. My plan is to install the os on /dev/sda (8006), and data on /dev/sdb (9550). Unfortunately, the 9550 comes up as /dev/sda. The 8006 is installed in slot 3, which is a 100Mhz slot. The 9...

...ust go out and buy it. Unless you just want a 2 SATA drive version (the 8110 or 14" shallow 8115), the 8114 offers up to 4 SATA hot-swap bays in a sub-20" deep 1U rackmount: http://www.aslab.com/products/storage/monarch8114.html They seem to be supporting the latest 3Ware Escalade 9550SX, which it too new to trust IMHO. But if they feel differently, I'd trust them. At the same time, it wouldn't surprise me if they'd sell it with a Escalade 8506 series instead -- which I do trust (especially since with only 4 drives, I'd probably create a RAID-10 volume), and only d...

...We use Samba 3 server for some video stuff (editing, rendering, and so on) -- that's why performance is critical. We've tried a lot smb.conf options, but Samba can't satisfy our requirements.

Dear all, I have upgraded the kernel and it took my 3w-9550sx-8LP sata raid card out of the box. It also fixed the problem of getting obsolete channel (my posting last week).

Anyone have any experience with these products yet? We've got one in for eval, but I thought I'd also ask for experiences here... Thanks in advance. Dave Thompson The University of Wisconsin - Madison Computer Sciences Department

Hello, I'm planning a server migration and being able to mount xfs file systems with the live cd would be a cruical feature. So before I download and try ... can anyone tell me whether the xfs is included in the 5.2 live cd? Later on I'm planning to install a new system with xen, 3ware 9550SX-4LP and xfs. The xen domains are of course located on xfs partitions. Do these features come with the standard dvd or do I have to build a custom kernel for that? Under centos-4.5 I chose xfs for performance reasons. With 5.2, is it still the fs of choice when it comes to performance or do you...
