Re-doing WHS, with perc 5/i but retail drives in RAID 5

post #1 of 5
Thread Starter 
ok so I need to re-do my old WHS.... I'm running out of space and the drive performance has gotten pitiful.

my new server I will be setting up 1GB teaming NICs and using a Perc 5/i for RAID 5 on the storage. Another reason for the RAID card and setup is the extinction of WHS drive extender in the newest build of WHS.

So anyway I have the option of using 8 1TB WD Green drives, 8 1TB WD Blacks (non RE), or 4 2TB Seagate LP drives.

Is there anything I should be wary of when using either drive? I know WD Blacks have the TLER issue and I read all over that you shouldnt use consumer drives in any form of RAID. Yes I know there is some truth to that in critical enterprise situations (no I wouldnt use them in my servers at work, but thats hundreds of users and computers accessing files, not like at home where it's me and my kids)

I prefer to use the 4 drives over 8 for obvious reasons (less power, less heat, less noise, less space to try to squeeze them in etc etc).

so... what are your opinions / experiences with this?

Are you using WHS 2011 or V1?


Drive Blender has been released and replaces DE: http://www.wegotserved.com/2011/10/3...ddin-whs-2011/
EDIT: Nevermind, it isn't ready.

What are the prices/avaliabilty of each selection since there is a HDD shortage.


You might want to place your OS on a seperate disk/array.

First off, no point in teaming the nics imo, you wont get the throughput to need it w/ a perc 5/i in raid-5 w/ sata drives last time i checked the numbers.

I would probably get 2x 320/500gb laptop drives to run a software raid1 w/ for your os drives.


Also,

8 drives = twice the risk, is it really worth the extra 1tb knowing you have twice as many drives that could fail or drop out of the array?

afaik the only ones that were set up right were a certain version of the greens that you could fix the firmware with, I don't believe it works the same way now with current wd green models.

I know I would just go w/ 4x 2tb personally.

Another thing to consider is spending the money for seagate es drive (enterprise) because they share the same failure rate as pretty much any other hdd on the market, but are not only designed for raid, they come with a warranty that is almost no questions asked, let us send you a new drive. Plus, the two times i've called seagate (twice in the past 5-6 years or so) I have gotten an american to answer the phone. Just my two cents :\\

For my raid 6 I went with 8x 2tb seagate es drives and have not had a single issue since december or so w/ 24/7 uptime.

Another thing to consider is whether or not the perc is compatible w/ your motherboard, some are very hit or miss.

TBH, if I didnt need hyper-v and ad/server roles of a domain, I would probably just build an unraid plus box.

Sure he will... a single 1GbE connection is capable of around 100-120MB/s. A single HDD can surpass that. With 4xRAID5, the array will be able to hit at least 300MB/s sequential read.

No, you definitely do NOT want to run software RAID1 for an OS. Actually, I am not sure you can even do that. Software RAID runs within an OS. He will be fine with a firmware RAID on his motherboard.

Dual NIC for multiple computers to be connected and load up databases and collecitons faster (i.e. my movies database loading for snappier UI, while my son or daughter is watching a movie or listening to music)


I ask on the drives because this is what I have on hand right now

yes should have added the risk factor in with my benefits to 4 over 8

I'll be moving to WHS 2011

OS drive will be seperate (well I hope..... i havent read up on WHS 2011 if it is like WHS v1 and the OS drive gets added to the pool or not). I have two 300GB SAS drives I'm goign to mirror for the OS if this works out. The mirror will reside on the PERC if I only use 4 2TB drives)

no worries on the perc compatability as this is the original machine the perc was in (Dell 690 workstation) Dual Xeons with 8GB mem. (old WHS was a old celeron 3.2GHz with 2GB of mem slapped together in a second hand 4U case lol)

I've already bought the 8484 to 4x SATA connector for the PERC card also if anyone goes to ask that next.

I plan on using 3 in 2 drive bay holders for the drives since really there isnt enough room to mount them any other way. (in case that gets asked)
