Raid 5 Controller Scramble!

The hardware vs software issue is a clear software win here.RAID5 being a pain has nothing to do with hardware vs software RAID.I agree, if you have to use MS and Apparently when I plugged them back in, they were in the wrong order. It's also known as "disk striping." With RAID 0, data is written across multiple disks. navigate here
Other RAID Levels There are other RAID levels: 2, 3, 4, 7, 0+1...but they are really variants of the main RAID configurations already mentioned, and they're used for specific cases. But that's more of "if you have MS or VMware, this is the option you get", not "software RAID universally sucks". 1 Serrano OP Ian S Jan 2, Thats 4 IOPS for a single write operation, and (unless a full-stripe write) they must all be done regardless of it being hardware or software.

Although I am still interested in learning about how to handle this type of scenario in RAID and in Storage Spaces. It combines the mirroring of RAID 1 with the striping of RAID 0. I came home and installed them, but in order to replace the front fan I had to pull out the HDD cages. Fault tolerance lessens interruptions in productivity, and it also decreases the chance of data loss.
Then the Controller said 2 drives failed! bassetman, Jul 1, 2003 #2 JROYCE Thread Starter Joined: Jul 1, 2003 Messages: 7 Please do send these notes if they cover the problem I am running into. But yet, the RAID array stopped working even though all the hardware seemed okay. 3. By this time I had unhooked the 3 drives that windows sees, and left the other half of the mirror connected, so that just in case something wiped out my RAID
Which of the following retains the information it's storing when the system power is turned off? If doing full-stripe writes, again software and hardware end up getting the same benefit - already having all of the data for a stripe available lets them skip doing any reads, bassetman, Jul 1, 2003 #4 JROYCE Thread Starter Joined: Jul 1, 2003 Messages: 7 Please send me the notes you have on this as it may help. Now the Controller card is all confused and doesn't have the correct IDs set for the RAID disks.
RAID 3 is seldom used except in the most specialized database or processing environments, which can benefit from it. •RAID 4 is a configuration in which disk striping happens at the You should have bought 4 to start with, that way in the interests of efficiency, you only need to complain that you're broke once #7 pricklypunter, Mar 13, 2016 BackupProphet I think we've both thoroughly clarified our statements at this point, but that's what I was responding to at the time.As we've both posted, you're going to want (or not have First Name Last Name Email Join Now or Log In Oops, something's wrong below.

One additional point to remember is that RAID 1 cuts total disk capacity in half: If a server with two 1TB drives is configured with RAID 1, then total storage capacity

Advertisements do not imply our endorsement of that product or service. his comment is here I've never seen a RAID card with actual NVRAM for its cache, as that would be very expensive - instead they all use regular DRAM combined with a battery or some
But that's more of "if you have MS or VMware, this is the option you get", not "software RAID universally sucks".You're putting words into my mouth.1. Hardware RAID does have the advantage that only the original single write operation has to travel over the PCIe bus to the RAID card - the card can then do the The RAID controller should be placed to one side and studiously ignored.
Modern CPU's, a little memory coupled with modern file systems places it head and shoulders above a hardware based solution now in my opinion, however in saying that, there are times

Using the example of a raid-5, unless you are doing a full-stripe write, the efficient thing to do is read the old data + parity, use that with the new data The first task is to clone each and every one of the hard drives which have been involved in the array, this will often include an extra drive or two which This is the RAID level ideal for highly utilized database servers or any server that's performing many write operations. Backing up to a RAID device might well be a part of such a strategy.
