similar to: SCSI Raid

Hi everyone, I'm looking into setting up a SATA hardware raid, probably 5 to use with CentOS 4. I chose hardware raid over software mostly because I like the fact that the raid is transparent to the OS. Does anyone know of any SATA controllers that are well tested for this sort of usage? From what I can tell from googling, this is more or less where RHEL stands: Red Hat Enterprise Linux

Hi, On my x86_64 system I have a SiL311x controller that can do RAID. If I configure my 2 identical disks in a RAID1 setup, I would expect to see only 1 block device on Linux. Still I see 2 block devices. Is this intentional, and if so, isn't that dangerous ? (i.e. writing to both disks at the same time) Anyone with an insight, please explain :) -- dag wieers, dag at wieers.com,

Is anyone running either the newish Adaptec 5805 or the new LSI (3ware) 9750 sas raid controllers in a production environment with Centos 5.3/5.4? The low price of these cards makes me suspicious, compared to the more expensive pre-merger 3ware cards and considerably more expensive Areca ARC-1680. I've been 'burned' by the low cost of Promise raid cards (just as this group pointed

Greetings, Can anyone relate experience(s) installing CentOS on Compaq rack mount servers units please? Easy no problem, easy some issues, or ghastly do not do it under any circumstances... ;) Basically, I'm looking at some used/refurb dual PIII units and will run RAID on Compaq built in SCSI or is it easy to pop in some 3ware SATA in them? Let me know in terms of CentOS 3 and/or 4 please.

Got a new box I'm trying to set up. I configured the RAID from the firmware, but "fast initialize" was sitting there at 0% (it's about 43 or 45TB). The first time I tried this, I said background, and rebooted the system. And the stupid annoying alarm started up as the system came up. This time, having *finally* figured out how to set up hot spares from the WebBIOS, I suspended

Hello list. The next days we are going to install Centos 7 on a new server, with 4*3Tb sata hdd as raid-5. We will use the graphical interface to install and set up raid. Do I have to consider anything before installation, because the disks are very large? Does the graphical use the parted to set/format the raid? I hope the above make sense. Thank you in advance.

I need a SCSI card to attach a tape library to my system. I am looking at the Adaptec 29320A-R. Can anyone confirm that this card will work with the stock CentOS 4 kernel? -- Bowie

What model LSI card? Is that card on the RHEL hardware support list? Does LSI/Dell have drivers on their site? Have you tried drivers from LSI/Dell and using the dd(driver disk)

Dear Experts, one of the RAID threads today prompted me ask everybody. Which internal hardware RAID controllers will survive some future to come in your estimate. First of all my beloved 3ware finally seems to have passed away. After multiple acquisitions and becoming part of LSI and getting bought with LSI, it probably became non operational. Namely, the latest 3ware cards have ancient

I don't believe that is correct. LSI acquired 3ware, and Avago acquired LSI. So, Avago owns the 3ware and LSI technology, but Adaptec and Areca are still competitors. > Whoops, Avago is now Broadcom, a

Hi, Running a bunch of CentOS servers on 2U supermicro equipment, usually with 8 drives on Adaptec SmartRAID V or LSI Megaraid. In designing a rack in a data center, the question arises as to how to measure the amperage the server uses, prior to investing in power drops that actually do that for you, even remotely, for about $260.00-300USD per unit. This number is the important one these days

I have an Infortrend RAID box I'd like to see as one big 6TB partition, but I only can get 2.2TB partitions to work. I was trying to do this with an Adaptec controller but apparently they are only (any of them) 48 bits wide. Does anybody have a working system for SCSI/Centos over 2.2TB?

I generally 3Ware controllers get recommended but the servers we are looking at getting use LSI Megaraid SATA 150-4 controllers. I was wonder what experiences there are under CentOS 4 with these positive & negative? Regards, Paul Berger
