Using MSA50 As SAS JBOD?
The MSA 50 JBOD SAS enclosures have some kind of high density mini connector
on them that mates to the SAS RAID controllers like the P600. Does HP make any adapter that would allow us to use these boxes as a pure JBOD solution? I am trying to set up a testing station for SAS drives, so I need the computer to have access to the raw drive, and I certainly don't want the complexity of defining lots of individual RAID 0 volumes through a RAID controller. -- Will |

Using MSA50 As SAS JBOD?
Not unless the P600 or P800 has the ability to present all the devices as
JBOD, which I am reasonably sure they dont. Given the performance and availability of RAID, why would you want a JBOD setup? Worst case ... Make one massive RAID Voulme, and partition the hell out of. Although, it would be preferable to have have discreet array volumes with a single partition, rather than one volume with loads of partitions. -LC "Will" wrote in message ...

Right, but the question was how do I connect this to the MSA50 enclosure. MSA50 is using some kind of high-density connector I don't recognize. Is it proprietary to HP or industry-standard? -- Will |

Using MSA50 As SAS JBOD?
i believe it is proprietary ... its like a 16 lane SAS connector, or
something. I dont have any MSA20/50's in my environment yet, so I havent had to dig into the specifics with this gear. All i know is its an HP ONLY solution. Im guessing you have to set up lots of 0+1 arrays with 1 drive in each of them if you want to test individual performance. - LC "Will" wrote in message ... "Phil" wrote in message ...

All i know is its an HP ONLY solution. Im guessing you have to set up lots of 0+1 arrays with 1 drive in each of them if you want to test individual performance. To do what you're asking, I would simply create a bunch of single-disk arrays in the array configuration utility. You will get errors when you have to pull a drive out, but the controller will allow you to do this, and will re-present the disk to the OS. I don't know what the limit for arrays is in a P800 or P600. If you go with mirrored pairs, you'll have a wait for a rebuild when you remove a disk. thomas. |
