Achieve better I/O
Guys am running a filehost and now am facing i/o issues.
So how can i improve the i/o speeds using RAID concepts ?
I have option to choose among these two

Which is best to choose and what specs offer best I/O as my site will always have 500mbps in and out.

Your server configuration only differs by CPU... not I/O configuration. So it's better to go with the Xeon E3-1230.
By the way, if you're doing 500 Mbps all the time, you'll use 156.744947 terabytes / month, which is 56 TB more than your 100 TB configuration.
Pentium G850 OMG!
which config is best for better i/o then ?
I am using XFS Script.
How much disk space do you need?
5tb minimum
For 5TB you can either do 4x3TB RAID10 or 4x2TB RAID5
the RAID5 will be bad for writes, but for reads it should be OK.
4x3tb Raid 10 will give 5tb usable? and it is best for read and write?
4x3TB RAID10 is 6TB
4x2TB RAID5 is also 6TB
RAID10 would be best if you care for both read and write.
If you only care about read - RAID5 might be better.
2x4tb SAS with raid 1 is better than 4x3tb raid 10 ?
4TB SAS drives @ 15k, i don´t see this drives. You mean 4TB SAS (WD4001FYYG) drives with 7,2k?..You should go with minimal 4 drives.
If you can squeeze in a 60ish GB SSD's for caching would give you a nice boost. I don't think it is possible to do 4xHDs + 1SSD with the HP. Which leaves a RAID5 config 3x3TB + 1 SSD (if my wildly guessing is right).
@EricS I am wondering how SSD caching will work for RAID5.
I think that question was answered last month by @Mun
For 4tb usable 4x1tb with RAID 0 will give much faster speed than any other raid is that true?
Yes, it is true. However with RAID0 if one of the disks breaks, all data is lost.
``> @rds100 said:
Is there any other RAID methods which combines the method of RAID 0 and gives better I/O alongs with safety(mirroring)
Or
Any other technique?
Cpu : Dual Core 1.5ghz
Ram : 16gb
Hdd 4x 2tb hdd with RAID 10 BUU Controller.
Can the above server handle 5tb data transmitting daily (read and write) without i/o ?
Use a RAM drive or so to hold files which are frequently accessed ? so that the disk won't need to be accessed so frequently for those files?
RAID 10.
