Hi guys. I just recently bought this controller :
http://www.addonics.com/products/host_controller/adsa3gpx8-4e.asp Plus : 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 /dev/ada0 512 # sectorsize 1000204886016 # mediasize in bytes (932G) 1953525168 # mediasize in sectors 0 # stripesize 0 # stripeoffset 1938021 # Cylinders according to firmware. 16 # Heads according to firmware. 63 # Sectors according to firmware. WD-WCATR5253676 # Disk ident. Seek times: Full stroke: 250 iter in 5.055337 sec = 20.221 msec Half stroke: 250 iter in 3.685852 sec = 14.743 msec 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 Transfer rates: 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 HDs. 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 ) some additional info : siis0@pci0:9:0:0: class=0x018000 card=0x31241095 chip=0x31241095 rev=0x02 hdr=0x00 vendor = 'Silicon Image Inc (Was: CMD Technology Inc)' device = 'PCI-X to Serial ATA Controller (SiI 3124)' class = mass storage aac0@pci0:7:0:0: class=0x010400 card=0x02ca15d9 chip=0x02859005 rev=0x09 hdr=0x00 vendor = 'Adaptec Inc' device = 'PCIX133 32/64bit (Adaptec 2410SA SATA RAID)' class = mass storage subclass = RAID Thanks. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hardware To unsubscribe, send any mail to "[email protected]"
