Hi

1. Yes. I have the SCSI RAID controller Adaptec 2100s (http://www.adaptec.com/worldwide/product/proddetail.html?prodkey=ASR-2100S&cat=%2fTechnology%2fRAID%2fRAID+for+Entry-Level+Servers+or+Workstations) with 2 IBM 36LZX (http://www.storage.ibm.com/hardsoft/diskdrdl/ultra/ul36lzx.htm) (10000rpm, 4MB cache).
How much did I pay for? You don't want to know... http://www.sysopt.com/forum/smile.gif
How fast are they? well, configured in RAID0, they are too fast.
2. SCSI controllers? Adaptec (http://www.adaptec.com) , LSI Logic (http://www.lsilogic.com/products/storage_standard_prod/index.html) , Tekram (http://www.tekram.com)
SCSI HD? IBM 36Z15 (http://www.storage.ibm.com/hardsoft/diskdrdl/ultra/ul36z15.htm) or Seagate X15 (http://www.seagate.com/cda/products/discsales/marketing/detail/0,1121,243,00.html)

does it? (i am new to scsi)

I have a 3 channel MEGARAID controller that I paid $150 for. I already had the cache memory, so I didn't have to spend more to get cache. I have 3 IBM DNES 318350 disks in a raid 5, each costing $180. How fast is it? Well, it is definitely faster than anything i have ever seen, but I was not so much concerned with speed as I was was redundancy. Of course, the speed is nice to have. It really shines over IDE raid configurations in multiple simultaneous read/write scenarios. IDE will choke a bit in those situations.

As for your third question, the answer is most likely yes. Adaptec and Seagate make excellent products that have worked well together in the past.

Yep, they will work just fine...

Hi AndreRIO,

Sounds as though you're ready to immerse yourself in SCSI technology. I'm using the Adaptec 29160N adapter with two Seagate Ultra 160 Barracudas and a Plextor SCSI CD-RW. The 29160N might be just the card you're looking for. Roughly $250 as a kit with software, cables, manuals etc. Make sure you don't take anything less than the Adaptec kit as quality cables are vital with this technology. Good luck!

I'm also using an Adaptec 29160N with a Seagate Ultra 160 10,00rpm hard disk. I think it may be a wiser choice to get the Adaptec 29160 instead of the 29160N since it supports 64Bit PCI, who knows, maybe all mainboards in the near future will have 64bit PCI ports. And the cost difference between 29160N and 29160 is quite small.

[John Lowell]

NDC,

Interesting. I was encouraged to consider 64 bit by a particularly engaging Seagate customer service employee at the time I was purchasing my ultra 160s. A few questions: (1) is not the 29160 considered primarily a server card, (2) your 10,000 RPM drives, are they not Cheetahs and (3) if they are Cheetahs, are you having any problem whatsoever with noise?

Regards,

John Lowell

Hi, John

(1) 29160 is rated as a SCSI card for mid-range server environments. The reason it's considered a "Server" card is because it has 64bit/66Mhz interface. As you may already know, most high-end multi-processor server/workstation mainboards usually utilize 64bit/66Mhz PCI ports unlike uni-processor mainboards that have 32bit/33Mhz PCI interface. The 29160 is also backwards compatible with 32bit PCI interface... 29160 isn't only used for servers, they are used for multi-processor workstations as well...


2) Yes, my SCSI drive is a Seagate Cheetah (Ultra160). I have no problems whatsoever with it in terms of performance, reliability or noise. I use a lot of aaplications with heavy I/O data, and it sounds smooth. It's the quietest drive I have on my systems. On the other hand, my Western Digital which I've been using for over 2 years now sounds like a dang woodpecker when it's being heavily accesssed. That's what I noticed about WD drives, they're rather noisy compared to most other HDD's..

3) I've been using Seagate SCSI HDD's for quite some time now. I currently use 3 cheetah's and they all are very reliable.
