Great controllers never the less, RIS is forward compatible from x00 to x10 to x20 series. The other option is to create each disk as a single-disk RAID-0 array yes, it should let you do this. Sep 18, Messages: There’s RAID metadata on the disks, and the failures will produce unexpected results. But the P boards are huge, full length boards It may not even fit in my case, I may have to run it on my open aired test system. In the case that the batteries are dead unlikely , the impact to array performance is that the array accelerator write cache will be disabled. The battery is there to preserve data in the cache in the event of a controller power failure.

Use the excellent “TestDisk” utility, you can select the physical disk, tell it you had an Intel partition, and after a quick search, it should find your missing information. So, after doing this, Windows immediately pops up the new drive.
I’m not denying the value of experience, but you have to be careful what you learn from it, and specifically not to confuse correlation and causation; just because you had a couple of HDDs fail when batteries failed doesn’t mean battery failure causes HDD failure. Could it be because they probably haven’t been turned on hp smart array p400 controller a while just sitting around in some storage room?
Aha, so this bring back ol’ software vs hardware RAID war: I mean of course batteries will drain out on their own, but I’m assuming this is the case rather than a coincidence that both batteries are dead. Adding my thoughts here, since this hp smart array p400 controller up in my search results Then you tell TestDisk to “Write” the info back to the disk, reboot the computer, and voila!

Cheapest Option for Raid 0? Also, how would it affect my array if I use the xmart without batteries? Well, this is IMHO debatable. In my case, however, the P did recognize the disks as new and – without seeking my confirmation – it did auto-create a RAID-5 hp smart array p400 controller at the controller level as soon as I powered up the computer.
There are advantages to letting ZFS have the raw disks over a hardware raid controller.
But the P boards are huge, full length boards It may not even fit in my case, I may have to run it on my open aired test system.
So, some more hp smart array p400 controller arrya the HP Raid cards store all the array info on the drives themselves, not the card.

Their purpose is to provide power to the RAID contoller in the event of a power outage, to give enough time to write data that is in the buffer to the platters.
