1. Test bed

The testing environment includes host servers, HBA cards, HDDs, and switches.

All performance cases conducted here are on Windows platform. There are no

Linux, Unix, or Mac platform numbers. Details are listed below.

1.1 Hardware

Host servers

There are total 4 servers. Three are ASUS RS700-X7/PS4. One is ASUS

TS500-E6-PS4

Model name ASUS RS700-X7/PS4

Processor(s) CPU:Intel® Xeon® E5-2620 2.00GHz

Memory ASUS 8GB PC3-10600 (REG, ECC) with ELPIDA

On-board LAN Intel® 82574L Gigabit Network Connection

Model name ASUS TS500-E6-PS4

Processor(s) CPU:Intel® Xeon® E5520 2.27GHz

Memory ASUS 2GB PC3-10600 (REG, ECC) with ELPIDA

On-board LAN Intel® 82574L Gigabit Network Connection

iSCSI HBA cards

Device name Intel® 82574L Gigabit Network

Driver version 12.7.27.0

Hard drives

Seagate Cheetah 3.5” SAS 15K.5 ST373455SS 73GB x24

Benchmark tools

o Iometer 2006,07,27

o IOmeter settings

Cache hit : max disk size = 20480

None cache hit : max disk size = 0

# of outstanding I/Os : 64

Ramp up time : 5 seconds

Run time : 25 seconds

1.3 Storage target settings

RAID controller : Dual controller Q500-P10-D424

Firmware version : 1.0.0_ 20130425_1600

Host interfaces :

o Single controller : up to 6x 1GbE iSCSI ports

o Dual controller : up to 12x 1GbE iSCSI ports

Stripe height (KBytes): 64KB

Block size : 512 Bytes

Write back or write through : Write back

Best configuration suggestion

As a general rule of thumb, try to assign dedicated RAID group (RG) to each host

interface port. This will yield the best performance. If you assign each RG to

several host interface ports, this usually will result in not so good performance.
