similar to: [OT/HW] hardware raid -- comment/experience with 3Ware

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

My firmware seems to be more up to date. Anyway, I will try to update firmware. I have to check how to do that. # dmesg |grep LSI scsi4 : LSI SAS

Happy new year ! We have a SuperMicro server with a LSI MegaRAID 9260-4i controller. Since Centos 6.6 update (kernel 2.6.32-504), the controller doesn't initialize at boot. Reverting to kernel 2.6.32-431 allows server to boot fine. The server can't boot due to a bug in LSI megaraid module. Boot log ends by a lot of lines: RESET_GEN2: retry=xxx, hostdiag=a4 I tried Centos 6.6

Hello listmates, I would like to build a 12-15 TB RAID 5 data server to run under ContOS. Any recommendations as far as hardware, configuration, etc? Thanks. Boris.

Hi, I was wondering if anyone has successfully configured two lsi/3ware 9750-4i series controllers for multipathing under CentOS 5.7 x86_64? I've tried some basic setups with both multibus and failover settings, and had repeatable filesystem corruption over a iscsi(tgtd) or nfs3 connection. Any ideas? Vahan

Hi, I'm currently looking for a RAID controller with BBU/CacheVault and while LSI MegaRaid controllers worked well in the past apparently they are no longer supported in RHEL 8: https://access.redhat.com/discussions/3722151 Does anybody have recommendations for for hardware controllers with cache that should work in both CentOS 7 and 8 out of the box? Regards, Dennis

Hi, I've got a new server with a 3ware 9550SXU with the Battery. I am using FreeBSD 7.0-Release (tried both 4BSD and ULE) using AMD64 and the 3ware performance for writes is just plain horrible. Something is obviously wrong but I'm not sure what. I've got a 4 disk RAID 10 array. According to 3dm2 the cache is on. I even tried setting The StorSave preference to

Hi, I have been trying out a nice new tws controller and decided to enable debugging in the kernel and run some stress tests. With a regular GENERIC kernel, it boots up fine. But with debugging, it panics on boot. Anyone know whats up ? Is this something that should be sent directly to LSI ? pcib0: <ACPI Host-PCI bridge> port 0xcf8-0xcff on acpi0 pci0: <ACPI PCI bus> on pcib0

Hello All, What would be the lists recommendation for an 8 port controller with native support for Centos 5.0? Currently have a 3ware 9650SE which does not... Cheers Steve

Hello: I am looking for a recommendation for a PCI-e RAID card for my server. The server has a PCI-e x16 low profile slot so the card has to be at most 6.6 inches long x 2.536 inches high. I would like to use RAID 5 with 3 drives so I have to have those capabilities. It has to be CentOS 5.4 compatible (Of course!). I took a look at the offerings from 3Ware, but their cards are too long. If

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

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

Hi, we would like to establish a small Lustre instance and for the OST planning to use standard Dell PE1950 servers (2x QuadCore + 16 GB Ram) and for the disk a JBOD (MD1000) steered by the PE1950 internal Raid controller (Raid-6). Any experience (good or bad) with such a config ? thanxs, Martin

OK. And I'll tell you that none of the failures that I've seen in the last 15 years were a result of user error or poor configuration. > 1. Bad choice of drives

Hello list, I see through the archives that some people here use 3ware RAID controllers with Centos. I have picked up two 9500S-4LP controllers for future servers. I was hoping that if some people could please share their 3ware monitoring scripts with the rest of the group. What I am really hoping to do is have some setup where a cron job runs scripts to test each of the drives connected to the

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
