Solution for RAID5/6 8 Bay SATA DAS

Recommended Posts

Looking for comments or suggestions on the following:

OS would be WinXP or Vista, CPU is 3GHz dual core

Seriously considering doing this: http://www.amug.org/amug-web/html/amug/rev...les/enhance/e8/

1) HighPoint RocketRaid 2322 (mix of software and hardware RAID) - no RAID 6 option

2) Enhance 8 bay enclosure, either ML or eSATA connection (no single card supports eSATA option)

3) 8 500GB SATA drives

- Really don't like the connection options of ML or single eSATA to each drive and having 2 cards, but price, capacity, and performance are reasonable with the ML enclosure

- Worried that software RAID for 2322 will conflict with nForce4 ultra motherboard RAID 0 system drives

Need:

1) more than 4 or 5 drives for better performance and capacity >2 TB in RAID 5

2) must be DAS, not internal option (currently no room internal for more than about 4 additional drives)

3) better than 250 MB/s read/write RAID 5 performance

4) must be PCIe (at least x4), don't have PCI-X slot, x4 PCIe card should also work in x8 or x16 slot

Would like:

1) RAID 6 option, all hardware RAID on host controller/adapter would be great (expensive!)

2) direct connect with eSATA/xSATA from enclosure to controller/adapter, single ports on each

3) controller/adapter <$500

Does anyone have any comments on proposed solution or other suggestions that would work? Thanks!

Just to let you know, XP can not see volumes larger than 2tb. Don't know about vista, although everything I've read only says XP has this issue. My 3ware card has an "autocarving" feature for volumes larger than 2tb. Just some info for you.

Also, check newegg, b/c I remember there being a raid card with a 4x multilane internal and a 4x external which will save you a lot by not having to get an external enclosure that holds 8 drives.

*cough* crock of stinker *cough*

Explain this if you will.. xp.jpg

XP Pro X64. :P

i think its due to the 32bit XP which has limitations on the displayed hdd space.. just like its limited to 3GB for rams..

No, not at all. XP can not boot from an array greater then 2TB but it can read one up to 256TB or something crazy. XP has to boot from a MBR and that will only work on a 2TB or less drive.

32bit XP can't see GPT partitions.

XP x64 can see GPT partitions, but cannot boot off of them.

IA64XP can see and boot from GPT.

32-bit Server 2k3 (pre sp1) can't see GPT

32-bit Server 2k3 SP1 or later can see GPT but cannot boot of of one.

All versions of Vista can see GPT, but only EFI based systems can boot from them.
