I just recently bought this controller :
http://www.addonics.com/products/raid_tower/raid_rack.asp ( the one
with 4esata connectors in the back)
so I have a 8.1-RELEASE running and the controlled connected and the
siis driver loaded plus 10 HDs installed on the raidrack each 5 is
connected to a 5x1 port mutiplier and then to a esata.
so here is the issue :
1.- I can see just only from ada0 to ada6 I don't see any other HDs.
2.- Performance is just 131 MBs per second as report from diskinfo -t
superstorage1# diskinfo -t /dev/ada0

1000204886016 # mediasize in bytes (932G)

Quarter stroke: 500 iter in 5.924198 sec = 11.848 msec
Short forward: 400 iter in 2.157650 sec = 5.394 msec
Short backward: 400 iter in 1.785152 sec = 4.463 msec
Seq outer: 2048 iter in 0.292870 sec = 0.143 msec
Seq inner: 2048 iter in 0.232126 sec = 0.113 msec
outside: 102400 kbytes in 0.771598 sec = 132712 kbytes/sec
middle: 102400 kbytes in 0.925421 sec = 110652 kbytes/sec
inside: 102400 kbytes in 1.652984 sec = 61949 kbytes/sec
it should be more ?
3.- I have two different system with same controller one is a dell
2850 and the other one is a supermicro server in both I can see only 7
Could be a problem with the driver ?
So my idea was that to use this with ZFS and AOE so I can have a SAN
for my servers but I need to get the best performance possible.
I'm willing to buy another controller if is necessary, any
recommendations ? ( no more than 700 US )
