  1. Chris, Is it possible to scan this article and place it here? Thanx
  2. Clean install of Win XP (because one of my 3 X15's died ) on a Adaptec 3210s with 2 X15's in raid 0.

    Any comments on Adaptec 2100s?

    I'll keep my 2100s for the time being, replacement is expensive and who will buy my 2100s? Maybe Adaptec comes up with some answers but I don't expect they will be usefull. Gooed luck,

    Hoggy, seems to me we're in this together. My guess is you can't keep your current raid array with a different raid controller but I'm not sure about this. I allways hook up a big IDE drive (IBM 60GXP) to my system for data storage, backup or (in your case) to reinstall my config. Easy and not that expensive. I'm also not sure what the alternatives for the 2100s are, it's difficult to find any decent reviews on this subject. Maybe SR can?????

    That looks much better than my results in HDtach. What test did you run in Winbench 99? I have Winbench 99 1.1 somewhere, I can give it a try.

    I added this to my case, I wonder what they come up with next. Changing the IRQ from 16 to 10 or 11 means disabling ACPI and probably a reinstall of Win XP. I'd rather not. All drivers are up to date, Win XP delivers all except the latest IDE. The read write transferrate is about 55-65MB/sec according Atto. Did some more testing: - Transferred the 2100s to PCI-slot 1 (32/64 bit slot) - Disabled every other PCI card to ensure max availability of the PCI bus to the 2100s - Added a third Seagate X15!! - Benchmarked the new disk as single drive, 39MB/sec which is ok for this drive. -Added the new drive to the raid 0 array. benched again with Atto and HDtach, no improvments, the transerrate stays the same as with 2 X15 hdd's, below 40MB/sec where it should be well above 100MB/sec. - Benched again with Adaptec W2K driver 3.03 installed, no improvments. I'm a bit out of options, this card seems incapabale of delivering decent raid 0 performance. Can Adaptec reproduce my results????? Does Adaptec replaces bad performing cards? This card doesn't deliver what Adapatec promises on your website. Quote below: "Affordable, full-featured RAID solution for increased data protection and server availability. The Adaptec SCSI RAID 2100S card delivers high performance and availability for entry-level servers and workstations - conventional and rackmount. It is an affordable, micro-processor - based, fully-featured, Ultra160 SCSI RAID solution in a half size form factor making it ideal for environments that require greater uptime, high-speed throughput, scalability, and space saving features" No high performance or high-speed throughput over here. Thanx

    How nice :-( Any recommedations for another controller? I added a third X15 to my raid 0 array, no improvements.
  9. I opened this case at "Ask Adaptec". Any comments? OS : Windows XP Problem : 12/25/01 08:01:29 ardev1 I use a 2100s with two Seagate X15 18GB harddisks in Raid 0. I updated the controller firmware to the latest edition and replaced the 32MB cache with 128MB PC100 ECC. The problem is the poor performance of this card, it's performing worse than one separate X15. You can see the performance in this file: I checked all settings but can't find something wrong. I made a config file with storage manager pro which you can find here: Can you tell me what the problem could be? Thank you. 12/25/01 10:03:57 ardev1 I did some research one the 2100s in some messageboards, shocking. It seems I'm not alone, every owner of this card complains about the bad performance. In fact, every user has the same low performance, about 37MB/sec in every benchmark you can think of. Adaptec's standard answer to this problem is to add more drives?? This doesn't work, I've seen the results from other users. Does Adaptec acknowledge the bad performance of this card and what is Adaptec going to do about this? 12/28/01 04:54:44 ardev1 Thank you for your detailed answer. Here's my respons: 1. I already use the latest bios for my systemboard (Tiger MP with bios 1.03) 2. The 2100s already has the highest priority possible on the PCI bus. This can be set in the systemboard bios. 3. I know my hardware resources, no problems here 4. My system is conflict free. The 2100s has it's own IRQ (16) EBDA Relocation is enabled. 5. My hardware is correctly installed with the 2100s on ID 7 and the disks on ID 0 and 1. The disks are connected with the cable that came with the 2100s. Checked all settings you suggested in SMOR and Storage Manager, everything checks out. What's next? Can you setup a config with this card and 2 disks to verify my findings? Thank you Webmail Solution : 12/26/01 15:18:02 pass2614 Hello from Adaptec. There are many variables in a system that effect performance. We have noticed that simply inserting a controller in a PCI slot and connect hard drives does not guarantee acceptable performance. This email will provide a checklist for you to review for your system. Please see the following: 1. System board BIOS. Verify your system has the latest system board BIOS (CMOS). You may contact the system board manufacturer or their website for this update. There maybe unknown enhancements in a later BIOS revision that may effect the RAID Controller. 2. PCI Slot order. Your system board prioritizes how each PCI slot will receive hardware resources; such as Interrupt and load order of BIOS addresses. For this reason, inserting the RAID Controller in highest PCI slot, normally PCI#1 or PCI#2 slot, will encourage the system board to allocate a higher priority. Keep in mind, the system board is in control how hardware resources are allocated to the RAID Controller. 3. Hardware resource assigned. How will you know the hardware resources in your system? Most times your system board displays information on the screen before the system boots or you may find this information in the operating system. If you are still unsure, consult your system board or operating system manufacturer. For the Adaptec RAID Controller, you may find hardware resource information in SMOR. You may access SMOR by pressing Ctrl+A at POST. Highlight the controller on the left and press Alt+C to access the 'Configuration' tab. There, you will see the Interrupt assigned. It is recommended that the RAID Controller receive an Interrupt greater than 9. Again, the PCI Slot order or the system board BIOS will control which IRQ the controller will receive. 4. Hardware resource conflict. There are times where another device in the system, such as video card, IDE controller, network card, SCSI card or any add-in card or integrated device on the system board may receive the same Interrupt or share an Upper Memory Address as the RAID Controller. In SMOR, highlight the controller on the on the left and you will see SmartROM Configuration settings on the right. In the matter of IRQ conflict, inserting the controller in a different PCI slot may encourage the system board to allocate a different IRQ or you may access system board BIOS and you may have control by allocating the IRQ to the PCI slot that the controller is installed. The second possible conflict is Upper Memory Address overlap/sharing which can be resolved most times by enabling 'EBDA Relocation' in SMOR of the RAID Controller. 5. Hardware installation and setup - Unsure which PCI slot to insert the RAID Controller? 32bit vs. 64bit, 33Mhz vs. 66Mhz, 3.3v vs. 5v? Review the RAID Controller specifications and insert the controller in a PCI slot that meets these specifications. If you are unsure which PCI Slot to insert, review your system board documentation or call the manufacturer. - Use only compliant carriers, enclosures and high quality cables. - Do Not disable cache on the hard drives. Note: Hard drives that have 68pin interface are generally not designed for Hotswap enclosures. To avoid possible problems, it is recommended to use 80pin SCA interface hard drives for this purpose. Review SMOR (BIOS) settings The controller is recommended to be set at default settings, unless otherwise instructed. Access SMOR by pressing Ctrl+A at POST. - Configuration settings Highlight 'Configuration' on the left side and SmartROM Configuration tab appears on the right. 'DOS/Windows 3.1 Cache settings' . The default setting is Write Through to avoid problems that can occur during operating system installation. Note: This cache setting has no effect on controller cache operation under Windows 2000, NT, ME, UNIX or NetWare. - Controller information Highlight the RAID controller on the left side and Information tab appears on the right. The information on this screen is information only and can not be edited. .Note the Revision. Check the Adaptec website for the latest revision. Note the amount of memory/cache capacity is correct - BUS settings SCSI ID should remain at 7 Note Transfer Rate is correct Note Termination is correct Note TERMPWR is correct - Drive information Verify each hard drive that is physically connected to the controller appears on the left side. The information on this screen is information only and can not be edited. Note the Revsion (Contact hard drive manufacture for latest revision) Note the Transfer Rate is correct for the hard drive. (If it is not, it may be related to a incompliant or faulty cable, carrier or enclosure that hard drive is connected) Note Status reports Optimal - Array information Highlight the RAID array on the left side and Information tab appears on the right. The information on this screen is information only and can not be edited. Note the Status reports Optimal Operating System - Note the operating system has the latest service packs. - Note the latest RAID driver is installed. Optimize Storage Manager Sofware - Run Storage Manager classic - Double Click HBA (Host Bus Adapter) - Click on 'Configure' button - Click on Cache - Set 'Cache Inhibit' settings from Mandatory to Advisory. - Click on Switch-View button at top. - Double-click the array - Click on 'Configure' button - Change setting to Write-back instead of Write-through After reviewing the above hardware and software settings, you will see how so many items in a system can dramatically effect performance. Thank you for using Adaptec's ASK US System. 01/02/02 00:58:12 yue21938 Hello from Adapec, I'm responding to your questions on Adaptec SCSI Raid 2100S. I noticed in your last message that the Raid controller is on IRQ 16. IRQ 16 is a mapped IRQ appears to the Operating System only. Please try to force the Raid controller to IRQ 10 or 11. You may refer to our ASK article # 010413-000007 on how to solve this issue. You can find this article by using Search by Article Number option at: p_sid=z-Ri5c4g&p_lva=&p_sp=&p_li= Please try also updating all the drivers of the motherboard chipsets in case you have not done so already. I would also suggest you to check the sustained read write rate of the hard drives. Thank you for using ASK system.
