Storage Expansion on DP 1.8

Storage Expansion on DP 1.8 - 06/29/06 08:22 AM

Hi,

I have a G5 DP 1.8 late 2003, with 2.5BG Ram, ATI 9800xtPro Special, Decklink Extreme Video Capture Card, Atto Express Dual SCSI Adaptor & an external enclosure with 2 raided seagate 73GB U320. with a sole use that is video editing.

I need to expand this workspace! My main concern is that Apple provides conflicted information on my powermac's motherboard support of PCI or PCIx... it has been said that if I have 8 memory slots then it definitely is a PCI-X one! still I am not sure!!!

I have to combine or choose one of the following... and each is a separate question here:

- to add an internal HDD of 400 or 500 GB... what would be the best option you'd recommend?
- to expand my SCSI workspace by adding - and raiding - two new SCSI U320 drives of 146GB each at least... would I need to get a certain Seagate model or can I raid 2 different SCSI U320 driives to the 2 Seagates I already have!! Please advice...
- to add a LaCie PCI-X raid SATA solution of 1 TB or 1.25 TB... these are the TwoBig & the S2S... but I need to make sure whether I have PCI-X or only PCI... how to really make sure of that???

I purchased this system in May 2004, so I guess this emans that it is not one of the infamous July 2004 DP 1,8???!!!!

All advice will be HIGHLY APPRECIATED!

I did check specs on apple.com by my SN... and I really was amazed as they did figure out that I bought by the end of April 2004, but the specs page I was referred to had no DP 1.8!!!! it had one DP only which is DP2.0!!! the only DP 1.8 I was able of finding among the different G5 specs pages was a July 2004 release & had only 4 slots for memory (I have 8)!!!

Is there a way one can contact Apple efficiently? or could anyone around here help me understand & reach some kind of a decision...

The original PowerMac G5 (which yours would be as a 2003 model) single and dual 1.8s had 8 slots and PCI-X. The single 1.6, and all the later 1.8s had 4 slots and PCI.
So you are correct when you say 8 slots = PCI-X.

Thanks guys, yes, I am sure now that it is PCI-X... one of the tips I got and was physically helpful is that a PCI is about 3 inches long & a PCI-X is about twice that.

I have one question left out of my list:

to expand my SCSI workspace by adding - and raiding - two new SCSI U320 drives of 146GB each at least... would I need to get a certain Seagate model that is compatible with my old 2 seagate drives? or can I raid 2 different SCSI U320 driives to the 2 Seagates I already have!! Please advice...

RAIDing different drives is not really true RAID. Its called JBOD (Just a Bunch Of Disks). For true RAID you should use identical drives. Model and capacity.

Thanks loads,
I was given the same note by the support of ATTO, while the support of Seagte suggested that I buy larger Seagate hdds & never mentioned this point!!! bad when support & sale have the same approach!!!

Thanks again!
