Hard disks, solid state drives
Need help with SCSI massive creation. . .
I "m planning a digital video capture system. Need Your advise pls...
i gonna use ASUS CUV4X-DLS mobo with LSI 53C1010-33 Ultra160 SCSI controller (2 channels / 68 pins). I want to connect next devices:
1. IBM Ultrastar 18ES DNES-318350 18 (GB) 7, 200RPM Ultra2 - boot drive
2. 2 x Seagate Cheetah 36XL ST318405LW 36 (GB) 10, 000RPM Ultra160 -
apps & video data
3.. Plextor CD-ROM UltraPlex x40 Wide (Wide Ultra).
4. Plextor CD-RW PX-W1210TS UltraSCSI.
5. Some SCSI Umax scanner.... (using converter)
I wanna know how to connect devices above without loosing speed
cause of slow devices (such as slower IBM Ultra2 drive, CD-ROM / RW)
I "m really new in SCSI world, and time is an issue:. (
Thank You all!
PS: sorry for english.
1ch: IBM + Seagate + Seagate
2ch: Plextor + Plextor + Umax
1ch: IBM + Plextor + plextor + Umax
2ch: Seagate + Seagate
Which case is most optimal, and why?
What speed will i get from Ch1 & 2 in both cases?
Cause IBM is pretty fast for CD-RW / ROM connection (UltraSCSI), but i don "t know if connecting it with Seagates will slow the performance of two Ultra160 drives for video storage. (And RAID0 if any)
In the second version, CD and the scanner will lower tire SingleEnded mode, and thus IBM will be able to work only in the mode of UW (40MB / c) (and it really is and not give so much...). This Seagate will feel at on the highway.
In a first embodiment, the tire in LVD mode, and drives - who was capable, ie, IBM -.. 80, Seagate - 160. If while working with Seagate will not be parallel to such a swap on IBM - this option is also viable, He offered his t. to. I do not know what else on this machine will be done. . .
second option is preferable, but on the first channel can be a problem at IBM and Plekstora (CD-ROM UW) due to a possible imbalance bus, ie a CD-RW and scanner -.. 50pin.
Moreover, the scanner cable at least 50cm. On the scanner must be active! ! ! and only terminator. Problems can only be at UW speed. If you omit the IBM and CD-ROM to the FW (20Mb / s) - must all work even with a passive terminator. . .
P. S. And ideally buy a four-thread type b / y Tekro 390F (UW) and hang on it all apart discs. Then the disc is completely hands are untied. . .
Thanks a lot guys!
