first i want to thank for help anyone who at least tries. We need to build good affordable storage for file server (lots of downloads).
Now we have 2x SC846TQ filled with 23x1TB hdds and 1x250GB system, attached on 9650SE 24 port raid adapter AMCC, with 8Gs ddr2 ecc fbdimm, motherboard x7dwe and xeon e5420.
HDDs are attached paralel, so no raid etc..
What is the best software solution with this hardware ? Now is transit per one server in primetime highest 700mbit/s, average 500mbit/s.
I mean what raid to use, raid 10 ? raid 60 ?
Would more ram affect transfer rate ?
Goal is to achieve most capacity for best performance.
Second, we got offer for next servers:
1x Supermicro® CSE-847E16-R1400LPB 4U chassis
1x LSI SAS 9260, PCI-E 6Gb/s, SATA/SAS 512MB RAID0,1,10,5 8-ch, bulk
1x LSI Battery Backup Units for 8888EM 2 ,9260
8x Cable, SFF8087(miniSAS) to SFF-8087(miniSAS), 600mm
4x DDR 3 ...4GB .......1333MHz ..ECC DIMM CL9, Dual Rank......Kingston
1x Quad-Core Intel® Xeon™ E5507- 2.26GHz/4.8 GT/sec/4MB/bez chladica
1x Intel® Nehalem cooler till 130W
1x Supermicro Motherboard Xeon X8DTE-F bulk
36x Seagate Constellation ES 2TB 7200RPM 64MB 3Gb/s SATA (we would like to change it for desktop as they are almost twice that cheaper)
is this good , what would you change, what raid would you use etc..
