Where are you guys getting your hp sas expanders from? Looking to buy one and was open to picking up a used one but nothing good on ebay now. Have you all found them there and about how much do they run? Look to be about $300+ on most sites new.
Hi, it's been a while since this topic has been visited. Has anyone had any success using the HP SAS Expander with an Adaptec RAID card? I understand maybe firmware v1.0 works, but any luck with 2.02 or above and recent Adaptec firmware? Thanks, Hammer8
Anyone know if the HP Expander is compatable with the Rocketraid 3560 or any of the 3500 series cards?
RocketRaid 35xx controllers are SATA controllers based in the IOP 341 controller (not SAS) and are not compatible with any SAS expanders, HP or otherwise.
Could just do this: http://hardforum.com/showpost.php?p=1035347825&postcount=287Can anyone recommend a bare bone motherboard just to use to power up the hp sas expander? dont need a cpu / memory etc, just a bare motherboard to power up the hp sas expander card.
they don't update their big all-encompassing firmware disc every time there is a minor revision to one of the member items - just like microsoft doesn't release a new service pack every time there's a hotfix/patch. that's why HP instructs you to grab the most recent firmware file for a particular component and drag&drop it into the correct folder on the USB key you made of the big firmware update disc. its pretty easy.

I have one in my second chassis and its working pretty well.
Unfortunately no. Only way that would work is if you had a momentary switch that was normally closed. Alternatively a toggle switch would work too, but the usual power button on a case like the Norco ones won't work.For that board, cant u install a regular atx power switch instead of jumpering the ATXCTL1? That way you can use the switch in the front of the case to power it on/off?
LSI 9240-8i/ 9240-4i works fine with HP SAS Expander if you configure it from WEb BIOS inside console. Windows MSM and Mega Cli cannot see correct HDD numbers, so you cannot create RAID from all disk in windows. I also tested HP P411 from two servers because I creating windows cluster with HP SAS Expander. Such config works great, but if you start LSI and than HP P411 connecting to the same expander , LSI lost disk configuration. However HP doesn't lost disk config if you attach LSi without config, I am using HP for RAID 10 it works great for me.
ah, nitrobass24, that be HPC clustering, I be thinking about failover clustering. Specifically, hyper-v with live migration & CSV.
What I do now: Supermicro twins, hyper-v cluster, storage on VHDs in CSVs on iSCSI targets, accessed via 10GbE. My iSCSI target is Starwind - two boxes, with their own raid and disks, and synchronous replication between the boxes (at least, I will do that when they rease 5.5). Still, Starwind can use system ram as WB cache, so you can have seriously large WB cache. From cache or RAM disk it can easily saturate 10Gbe and I have freedom of choice about my NICs, RAID and disks.
10GbE is fast, but it's not as fast as SAS. Still, 40GbE products are starting to appear...
