Found a decent deal on a Higpoint 8 Channel SATA Raid Controller today. Kicker is its PCI-X. I wasn't aware their were even any PCI-X boards out yet? Will a PCI-X card be backwards compatible?
 
PCI-X is for the most part just a faster PCI slot. It has been shipping for some time now. Its backwards compatible with standard PCI devices.


PCI Express is a completely different animal. PCI-Express is a serialized arcitechture. Its not backwards compatible with standard PCI devices. It is capable of MUCH higher speeds than PCI-X. It will completely replace AGP and eventually PCI-X.
 
PCI-X is found on server mobos (almost, if not completely, exclusively).

I believe it's backward compatible all the way back to 32bit, 33MHz PCI, but don't take my word for that.
 
and workstations

My K8W has dual PCI-X buses
and not all cards are backwards compatible
though the spec is to PCI 2.2 (64\66, 32\66, 32\33)

http://www.tweakers.net/reviews/400
benchmarks start in earnest on page 8
(worldlingo will do the translation via urls Dutch > English)
but the benchmarks are in English
and about as accurate as is possible
the tweakers.net StorageMark 2003 is based off of IPEAK SPT
same as SRs benechmark 3 Platform
 
ahh geezs.. Sorry guys.. I always get PCI-X and PCI-Express mixed up... I was thinking PCI-Express..
 
That card in particular is backwards compatible.
I'll be purchasing that to consolidate the controllers in my server and add more drives in the next month, so I've already done some research. :)

what 1066MB/s aint enough for you? :p

More like I dont feel like a second mortage to afford a mobo with PCI-X.. :D

Thanks mike.. Might grab it for now then switch boards when I find a reasonably priced PCI-X

O yeah, one more thing. It takes a HUGE amount of use (like multiple users accessing multiple RAID 5 arrays on the same controller) to be able to actually get up there where PCI-X is.
You'd probably get more near the use of 64bit 66MHz or 32bit 66MHz assuming you're doing a low-use server or a video editing workstation.
Don't get me wrong, if this is a true enterprise class server used by a lot of people, it'd be silly for you not to save up for a PCI-X board.
I just want it for consolidation and RAID 5.
 
yeh I dont own a single ap that even comes close to touching that kind of bandwidth
but it came standard with the board, and its supports the amount of memory I wanted to run
currently at 4GB soon at 8GB, will support 16GB, not that I'll ever purchase 2GB sticks
 
8Gb ??? I'd be going Vmware and turn that into several PCS.. :D

You guys are probably right. PCI-X may be overkill. But 32/32 is not enough. Gotta find a decent priced board that offers anything over 32/32.
 
Uhm, if the raidcore is so great, then why don't NewEgg or ZipZoomFly carry any raidcore products, when they carry the full line of adaptec, lsi, highpoint, promise, 3ware, etc? I would wager there's a VERY good reason the two most trusted computer stores (at least mine) don't carry any of their products.

10mb/s may be exceptionally slow for write, but you must remember this card is only $180 and you do get what you pay for. Also, if you had even 2 RAID 5 arrays of 4 disks, it would probably be even tons faster as opposed to one array of 8 disks. I would wager the speed decreases exponentially on that card as the amount of disks in the RAID 5 array increases. It has a slow processor and a very minimal amount of cache.
I couldn't imagine the target market for the card (entry level server, workstation) actually having a need for an 8 disk RAID 5 array. Anyone building a mid level server would probably use a 3ware, Adaptec, or LSI product anyway.

For my application, it would more than suffice. As at the very most, it will have two RAID 5 arrays of 4 disks. At the very least, it will just be taking over the current configuration.
