New Hardware poweredge R720

[alo]

Good Morning All!

I have been adding agents to my current setup, and its time to order new hardware.
I am currently using desktop computers and have a few offices each on their own vicibox install. I want to combine them now.

This will be about 150 agents dialing pretty aggressively (dial rate up to 6 at times). I plan on having a few asterisk dialing servers in the configuration, but I am concerned about the main server database. Specifically the Raid and Hard drive config.

I plan to use the newest vicibox (4.0.3 64bit) and was looking for any thoughts on the hardware config below before I buy it.
I would be EXTREMELY Appreciative to anybody taking the time to offer their opinion.

I really Appreciate everything everybody does for the community here. Thank you

Anyone Have any idea if it would be better to have a Raid 10 config with 100GB Solid State Drive SATA Value MLC 3Gbps 2.5in drives or a no raid config with a 200GB Solid State Drive SAS Value SLC 6Gbps 2.5in Hot-plug Drive?

I'm not very familiar to big setups, but are you thinking about running all 150 agents on one server serving DB/web/asterisk?
That will not work of what I've heard because asterisk don't scale well, look up similar topics regarding setups and read the comments from the experts.

I would use raid on the database server because of the redundancy, look up carefully if the raid controller is supported using OpenSuSE

I choose the Raid 10 Config with the SSD. Its been working great.

RAID 10 on SSD is over-kill for 150 agents, SAS drives will do just fine.

If money is of no consequence, go for SSDs. They are far superior in performance and reliability over traditional harddrives (even the SAS drives on RAID10). Though RAID 10 is overkill. RAID 1 should be sufficient for SSDs. Unless you're really doing a lot of disk writes and you really like overkill setups (I like overkill with SSDs. Hehehe!).
