Coulple Of Questions About Implementing RAID 0


When a filesystem consists of multiple block devices added together, all of them should be present, of course. Link Gerald February 21, 2014, 1:30 am @nihal, so we are only talking about basic RAID levels with parity e.g RAID-5 and RAID-6 In a 3 disk RAID-5 set, we have Sorry I would like to ask a bit more You opt for Dual mirror: so in that case, no need another drive for TM ? why is it required to have RAID 6 for double pairity ?

The more tracks you have in your project, the more strain is put on your disk. 10 tracks require 10 times the bandwidth of a single track. I know that adds to the cost but I like having a spare copy of data and I like having systems with disks that are all the same size. like the above 4 HD, do I need to spare 1 HD (in that case, 1TB) for TM, but is it enough ? Such systems typically use hardware controllers that do support hot swapping.

Raid 5 Explained

Peter Link Sudip Saha November 17, 2015, 7:00 am for video streaming which raid level is suitable? You can't, only subvolumes can be really snapshotted. And if backup is necessary, what type is best, tape, disk, online service? For more than one device, simply use mkfs.btrfs -m raid1 -d raid1 /dev/sda1 /dev/sdb1 will result in btrfs fi df /mount Data, RAID1: total=1.00GB, used=128.00KB Data: total=8.00MB, used=0.00 System, RAID1: total=8.00MB,

SSDs will get you much closer than any hard drive, but no storage media will actually ever reach the maximum transfer rate of the controller. With 2 disks, selecting RAID 1+0 effectively gives you a RAID 1 set. But what I feel is you should have included RAID 6 as it can withstand failure of more than one disk. What Is Parity In Raid Thank you in advanced!

Thanks! You could do worse, but apart from it being the Rolls-Royce amongst the hardware controllers, it is expensive like the car.Performance wise it will achieve around 85% (X-1) on reads and

What Is Raid 6

And thank you for the opportunity to play the babbling tech Link Gerald March 19, 2014, 11:33 pm Josh, just forget about RAID-0+1 (and 1+0 as well) this notation is now https://www.prepressure.com/library/technology/raid or Do we need 5 disk to have best scenario. Raid 5 Explained If for example i had a 10 disk raid 10 setup, if i pulled 1 of the mirrorsets (2 disks) would this result in data loss? What Is Raid 10 I would suggest to use them in a Raid1 configuration for security on the mobo, not in a Raid0.

Re: To RAID or not to RAID, that is the question Bill Gehrke Nov 18, 2009 4:10 PM (in response to Harm Millaard) With PCIe there has been an improvement with http://magicnewspaper.com/what-is/raid-0-or-1.html Current boards are relatively old designs and new designs are most likely immanent. What are the considerations for doing it either way? Reply Laurens says: July 5, 2016 at 7:08 am Having an extra offsite disk is a good idea. Raid 0+1

On some controllers such as HP ones, all available options can be selected even if there aren't enough disks available. Re: To RAID or not to RAID, that is the question Harm Millaard Dec 21, 2009 12:27 AM (in response to Kens10) You are new here, so you haven't seen this A 2 disk array carries twice the risk over a single disk, a X disk array carries X times the risk of losing it all.A RAID0 is perfectly OK for data http://magicnewspaper.com/what-is/really-simple-and-quick-raid-questions.html Re: To RAID or not to RAID, that is the question sarmour2 Nov 20, 2009 5:17 PM (in response to klfi) Klfi, I guess for your setup, as Harm observed, what

My question is, what raid will you recommend for me?

Link Jons July 28, 2015, 1:15 am Thanks Gerald! Reply Pinar says: November 18, 2008 at 7:36 am Actually you can have RAID 1+0 with only two disks. So check for that before making your decision.Cloning has saved my assets a couple of times now when my boot drive suddenly died one morning or I installed something funky and Raid 50 Since setting up the array will be expensive I want to have an idea of what the pitfalls may be.

What would be the best RAID configuration to use? I am also going to install your recommended utilities and system monitoring software. For overall speed of access to files, a lot of the time taken is in the first two steps: move the head to the right track, then wait for the disk http://magicnewspaper.com/what-is/what-provides-the-greates-storage-capacity-raid-0-or-raid-5.html It seems like Raid 3 can write in parallel in more than 1/2 of the total number of disks and lose only 1/4 of total storage.
