raid

I'm starting a thread to discuss the relative merits of the various RAID levels and their use, so others who are considering how to organize their arrays may benefit from the collective knowledge pooled. Welcome are links to any kind of academic research, benchmarks, or other articles exploring...

OK, I see all the major players, renaming their JBODs to Enclosures (I think this started with HP). To me this seems a little odd since I always felt a JBOD was just what it implied, Just a Bunch Of Disks and an Enclosure was synonymous with chassis. To me a disk enclosure could mean either a...

Do true hardware RAID cards, specifically the various LSI based cards, automatically enable CCTL / TLER and set the appropriate timeout delay on drives plugged into them, or is that something that should be done manually before putting the drives on the controller? IE: I buy a stack of...

I have an LSI Megaraid 9266-4i card with 22 1TB 7200 RPM drives attached as well as two 120GB SSD attached and for the life of me no matter what the configuration is I cannot get the performance to be consistent. When copying a large file it will start out at roughly 500MB/s then proceed to drop...

Hi guys, I have a DL380 G5 at home, with a P212 controller connected to an MSA60 via it's external port and 8088 cable. Everything with that works fine. I'd like to replace the P212 with a 9260-8i I had in an old machine, as it a better controller. I have an SFF-8087 to SFF-8087 cable...

Gang- I have an odd problem that neither Microsoft nor Dell have been able to resolve yet. I know many of you have lots of experience and knowledge on both the hardware and the software side of the equation. This is more of a post of desperation / check to see if anyone has experienced...

Hi, We are having 6 disks on our server with 5x480GB ssd and 1x120GB SSD and trying to figure out the best raid configuration. We are looking to configure with raidZ2 with 5 disks and to use one disk for centos installation. But I am afraid if it makes issues when the installation drive fails...

Hello, We are currently testing our using ZFS on Linux as a storage platform for our VPS nodes but we don't seem to be getting the performance figures we expected. Can you please provide some suggestions as to what we should be tweaking to reach higher iops? Hardware is SuperMicro with the...

Hi guys, we are looking to move our 8 disk RAID 0 (which is currently inside a workstation) into a 24 unit server chassis, so we can extend the Raid 0 to 24 drives and increase the max I/O of the Raid. Read/write speed is the most important factor for us - we deal with very large video/image...

In the past I used only software raid like Linux mdadm. Now I have this motherboard : X10DRC-LN4+ which has on board hardware raid : LSI 3108. I can access the management interface of raid during system boot up by pressing ctr+R. This maybe a noob question but how to enter into management...

Evening all, I am in the process of building a home ESXi server and have run into a couple of different issues. Was hoping someone might know more than I (easy enough in this case) and could possibility give me a bit of direction... This is the system that I've put together so far...

Hello everyone, this is my first post in this forum and i am looking forward that some of you might help me do decide. I've got an HP DL380G7 (with LFF Bays) and want to populate him as a ESXi Host with an Windows Server 2012 R2 Guest as a DC and Storage Server for my home lab and several...
