5U System - 2U Server + 2U JBOD + 1U UPS, Spec suggestions?

I am customizing a computing solution for academic research -- primarily used for large scale data processing / mining, database indexing, and student remote computing resources.

I have been having great success customizing a solution with [Silicon Mechanics](http://www.siliconmechanics.com/) -- from a customer service and cost standpoint -- and below are the relevant specs I've decided on. I've spent many hours trying to figure out the current server hardware, but I'm by no means an expert or even experienced with a task like this! Any advice would be greatly appreciated!

2U Server with 2.4GHz 8-Core Procs

* CPU: 4 x Opteron 6136 (2.4GHz, 8-Core, Skt G34, 512KB/Core L2 Cache, 12MB L3
Cache) 80W 45nm

* RAM: 128GB (16 x 8GB) Operating at 1333MHz Max (DDR3-1333 ECC Registered

* NIC: Dual-Port Intel 82576 Gigabit Ethernet Controller - Integrated

* SAS: Integrated LSI 2008 8-Port SAS2 HBA

* Hot-Swap Drive - 1: 600GB Western Digital VelociRaptor (6Gb/s, 10K RPM, 32MB Cache)
3.5" SATA

* Hot-Swap Drive - 2: 600GB Western Digital VelociRaptor (6Gb/s, 10K RPM, 32MB Cache)
3.5" SATA

* Power Supply: Redundant 1400W Power Supply with PMBus - 80 PLUS Gold Certified

* RAID Controller: LSI 9280-8e 8-Port External, 6Gb/s SAS/SATA, PCIe 2.0, 512MB

* BBU: LSI Intelligent Battery Backup Unit for 9260, 9261, 9280, 9750, 8880EM2 Controller

"JBOD Storage"

* Drive Set: 6 x 2TB Seagate Constellation ES (6Gb/s, 7.2K RPM, 16MB Cache) 3.5" SAS

* SAS 2.0 Expander: Expander provides connectivity to all drives and expansion port

* Host Port: Connection to host system: External SAS 2.0 (24Gb/s, SFF-8088)

* Expansion Port: Connection for storage expansion: External SAS 2.0 (24Gb/s, SFF-8088)

* SAS Cables: 1 x 1m External SAS Cable - x4 SFF-8088 SAS connectors

* Power Supply: Redundant 1200W Power Supply with PMBus - 80 PLUS Gold Certified

"Backup Power"

* 1 x APC SmartUPS 1500 RM 2U (intended for ONE of the redundant power supplies in each unit)

I'll also note that there are 32 RAM slots in the server (so half are free), and there are 12 bays in the JBOD (so again half free), both to accommodate future growth. Also, our budget is in the $10k - $15k range, which this satisfies.

  1. Hello, and welcome to THG.

    You are asking a lot. Why not build one at first to see where you go. If you need to expand, connect more servers to commit to a server farm, then by all mean expand. First start out with one unit and test it.
