    Seatools & Dell Not Work?

    SCSIMechanic worked great too. I was able to see that WCE "is" enabled on all the drives. The one thing I am still unclear on is how to determine if the drives are in Desktop or Server mode as mentioned by others that you can change with Seatools? ____________________________________________________________________________________________ The desktop/server performance mode (PM) option is proprietary extended mode page for Seagate SCSI drives, normally not included with SCSI software, only Seatools. However, the drive’s factory default mode is server (the best speed). Desktop mode require someone to actually use Seatools and change the flag to desktop. An indirect way to know determine server/desktop mode, is to run a test on bust speed, and seek rates: I the drive is in desktop mode, performance on the test will be noticeably outside factory specifications, even when compared with other Mfg. Maxtor/Fujitsu.

    Seatools & Dell Not Work?

    Seagate Seatools is unable to interrogate any Pure RAID cards, it will see HostRaid. Even if you have the drives attached to a regular SCSI HBA, and a RAID card remains actively installed, the application tends to freeze. There is no option to restrict the scan to a specific HBA; the scan includes every active card, with or without any drives attached: Seatools applications, as well as all other SCSI diagnostic software, provided by the major SCSI manufacturers were compiled back during the Ming Dynasty. It gets frustrating since you will need to physically remove the LSI MegaRaid controller from the PCI slot, and the LSI 1020/1030 SCSI controller as the only active SCSI controller. What HBA card is being used for the operating system drive? If is the LSI MegaRaid, problem, Seatools will still freeze, you will end up with the same problem: A complete hassle just to see mode pages from a SCSI drive. I would suggest that you download SCSI Mechanic 3.0 evaluation software. http://www.scsimechanic.com/ You will be able to see every mode page parameter of the drive. With the evaluation unit you don’t have the functionality to change mode pages, but at least you will determine the current drive's parameters: I will work with any SCSI drive, Raid & Regular SCSI HBA. The only caveat: if you need to see drives attached to any RAID card the drives cannot be in a raid configuration. They must individual drives attached to RAID card.

    Where to get Seagate 15k.4 FIRMWARE?

    If you are unsuccessful in obtaining a generic U320 firmware from Dell or Seagate, you may want to ask a SCSI Guru, that you may know, the actual SCSI mode page setting that governs U160/U320 interface. SCSI Toolbox Software allows you to ferret through all the mode pages stored on SCSI firmware; in addition the software provides diagnostic, and benchmark tools. For individual use, the software is expensive, targeted mainly for large corporate use, harddrive labs, or used by some Mfg. during field diagnostic use. You can request a 14 day, fully functional, demo via the website. If you can determine the mode page setting restriction for U160 interface, usually located in Operating Definition Page, you can change the drive’s definition to interface to SCSI-3 or SCSI-4 protocol; U320 depending on the Mfg. The software, I believe, allows you to make the mode page change temporary, for testing purpose, without immediately hardcoding the change into the drive’s firmware: Locate the definition page setting, and change the mode page parameter, and use the temporary change option; as a sensible precaution. Re-boot, without powering down the drive, test for U320 functionality, if satisfied you can access the same mode page again, and make the change permanent. If the mode page change did not work, usually the HBA controller is unable to interrogate the drive, or the drive times-out, then power down the drive, during the next boot-up cycle any temporary mode page change are reset back to the drive’s original firmware parameters. Again, you should have extensive knowledge of SCSI internal commands, or contact a SCSI Guru if you know one; to make sure the correct SCSI mode page setting is accessed. This software is targeted for seasoned SCSI experts; no safety nets are in place, except for the temporary option. There is one caveat: some OEM firmwares are compiled to disallow high level mode page changes, even with the referenced software: IBM is one of them. Good Luck JR

    Where to get Seagate 15k.4 FIRMWARE?

    Seagate is notorious for building dual interface OEM drives for the same model. A couple of yeas ago we purchased 4 ST3146707LC OEM drives rated as U160. I reached the the same conclusion that the U160 limitation is at the firmware level, and proceeded to flash one drive with a U320 Seagate generic firmware. The firmware completed without incident, and during re-boot, the drive continuously timed out during HBA interrogation. We were never able to initiate the drive. Based on what little information is available, these drives were a special request from OEM’s, used as replacement drives for legacy U160 systems. I believe the U160 restriction is not at the firmware level, but the controller board, and flashing a U320 firmware renders the drive useless. It may not be the case with your drives. Unfortunately the only way to test this theory is to actually flash a U320 firmware on one of the drives. If successful, you would proceed with the other drives, if not, you now have a nice paperweight.

    ideal hard drive configuration

    One of our associates actually tested for the best performance setup for 3-D software, to include Maya, Cad, and SQL database queries. After several setups, to include SATA and Raptor, the most optimal setup are individual 146GB 15K drives (Fujistsu MAU3147NP), 6MB RAM, and most important Windows Server 2003 SP1; configured as a workstation. The setup was installed in a Dell 670 with dual 3.6 GHz Xeon processors. 3-D applications, especially when rendering, will actually benefit more from additional RAM memory, as opposed to faster drives: Windows Server 2003 SP1 and the new x64 operating systems can access memory beyond the 4MB barrier imposed by 32 bit operating systems: Testing was performed with x64 Windows XP Pro & Server 2003 x64: The setup did not produce any quantifiable performance, and several issues with x32 registry entries made the setup impractical: Until applications are compiled as native x64, and fully optimized to use the capabilities of the new dual and multi-core Xeon processors, you are better off with the reliable x32 for now. In addition to tapping into additional memory, Server 2003 SP1 contains an enhancement in the device manager for the drives listed as: Enable Advanced Performance. This setting, especially with SCSI drives, modifies internal commands to access cache data faster: Quite impressive when you test with the flag on and off. Due to the excellent reliability of the new U320 drives, and brutal speed of 15K drives, we no longer create Raid configurations: Two 146GB 15K SCSI drives can quickly saturate a Raid HBA, even with a PCI-X interface: In addition, a bunch of excellent U320 enhancements, especially with Maxtor’s 15K II drives, coded on at the drive’s firmware level, are suppressed once the drive losses their individuality, and becomes part of the hive: RAID arrays. We automatically backup workfiles/projects data to an external SCSI enclosure with 4 300GB drives: The backup sequence writes the data to one of the four different drives: One drive can fail not all four: To date none of our SCSI drives have failed. The location of the page file is also overrated: Testing was actually done with no physical page file for Server 2003: The 6MB ram was being utilized by the operating system and applications without any degradation in performance. However, some applications still requires a physical hard drive page file; otherwise the application will not load.

    Fastest hard drive setup

    Your hard drive requirements should be based on the applications, or work you currently do, planning to use the computer for: The SATA interface is excellent for most users, but if you work with video streaming, SQL database, or high-end 3D rendering graphic applications you will find 15K SCSI extremely well suited for the task. Currently you have several interfaces suitable for workstation use, if you purchase a non-workstation system you will need to kwon the new computer drive’s interface capabilities: SATA SAS SCSI FIBRE We have tested several systems with the interfaces listed, and found the U320 SCSI and Fibre drives excellent for our requirements. Our SCSI setup includes only the Fujistsu line of MAT 10K and MAU 15K: We have tested Seagate and Maxtor, and found Seagate drives sluggish, and Maxtor drives run hot; even when air cooled. We also purchased a Fibre HBA, a 2GB 6 drive FC enclosure, and 300GB drives for an excellent price on EBAY: The enclosure is shared by three workstations, and the Fibre drives serve as backup storage since we no longer create Raid arrays.

    Will games benefit from SAS?

    Also I prefer to have SCSI/SAS Enterprise drives because of their reliability, this I really find important and I'm willing to pay more for quality. If a SAS setup is faster then raptors or not also depends a lot on what you do with the system. But you can hardly go wrong with SAS if you can handle the increased price over Raptors/SATA. When you need best perfomance/price ratio Raptors/Sata do better then SAS. However a good 7200RPM Sata disk will beat the Raptor if you look at performance/price ratio. Conclusion: none of the three (SAS/Raptor/7200Sata) options is wrong, so one should choose what he thinks is best or likes best, for me that is SAS for a friend of me it's 7200Sata. Willem. ___________________________________________________________________________________________ Based on testing environment results, the SAS protocol interface is not as stable as the old SCSI, or even faster in any Raid & non-Raid configurations: After reading so much on the technology for over two years, and the 16MB cache, I was expecting stellar performance from serial interface drives. Benchmarking several setups of SAS RAID arrays, and non-Raid for a client, we were disappointed with the results, and discovered only marginal improvements in the aggregate burst, transfer, and read/write rates when compared to the SCSI U320 15K drives (Seagate, Fujitsu, Maxtor). The Adaptec 48300 HBA used for testing, during boot up, was inconsistent in several setups, and would recognize all the drives, and then two drives would be missing. Microsoft and other backup/mirror software that interrogates the SAS drives falsely reports them as fibre channel drives, maybe due to the dual ported SAS feature, or the software requires revision to identify SAS interface: This created havoc when restoring saved image: Even the benefit of not having to manually assign the drive ID created problems with mirrored images. The SAS interface is excellent for Enterprise size scalability, and probably the 2nd generation HBA and SAS drives will outperform the current SCSI U320.
  8. Hi All: I hope someone could answer a fibre channel question. I’ve been working only with 1GB MIA interface, and I use the LC/SC to connect a 2GB JNI controller to the 1GB enclosures. I purchased, in route, a Fortra 4 bay enclosure with 2GB interface: The unit has two 2GB SFP transceivers. My question is what type of fibre channel cable combination do I require to attach the JNI HBA to SFP transceivers? Do I need an LC/ST, LC/LC, I have been searching the net, and maybe I am not using the correct terminology. If someone knows what fibre cable I would need to attach the JNI HBA to the Fortra 4 bay with 2GB SFP transceivers, I would be very grateful. JR

    SAS INTERFACE PROTOCOLS HELP

    Thank you for you detail information, I really appreciate it: I just want to get my feet wet into this new technology. I am not currently using any SATA drives only SCSI & SAS. I have a Dell 670 Workstation with 4 external Maxtor 15K 147GB in a StorCase enclosure, and would like to add four SAS drives inside the workstations; the 68-Pin SCSI cables were taken and incredible amount of real estate, and I was not able to properly installed the ATI X1900XTX, so I decided to use 80-Pin on the external enclosure. To be clear, the cables supplied with the card will interface the SAS drives, will the SATA power connector work on the SAS drives or will I need to purchase a 4-pin moles to SAS connector ot a SATA to SAS power connector.
  10. Hi Forum Members: I was curious about the SAS interface and decided to purchase for drives plus the Adaptec SAS Controller Card 48300; I have not received any if the equipment, but I think I am not very well versed into the plug and play interface of the SAS protocol. The Controller card provided cables for the SAS interface. What I am concern if is I require a dedicated power conversion from a Molex 4-pin or can I use the SATA power supply on the SAS, or will I require a conversion either way to apply power to the SAS drives, and will the cables provided by the Adaptec kit will work at 3GB or 1.5 GB. I also read the SAS interface is dual loop for redundancy; any input would be greatly appreciated on this process. Sorry for not doing my homework on the new SAS protocol; I am flying through the air without a net, but I got a great deal on 4 147GB 15K drives for under $ 200 ea & the Adaptec SAS controller. Thanks JR

    Hard Disk error in event viewer...

    I experienced the problem with SCSI drives. The problems related to the power cord & SCSI cable not properly seated on the drive and controller board.

    Manufacturer with Best RMA Process

    The problem with advanced replacement is that you have to be darn sure the drive is non-functional, and verify twice that the drive is actually defective, or your credit card will be charged in full for the replacement drive. Once the drive is received by the RMA facility; Maxtor or any other drive manufacturers will determine if the drive is actually covered under replacement warranty, even if a replacement drive was shipped: I know of two cases that involved RMA with “Advanced Replacement†on Maxtor drives: The retail value of the drive is held on the credit card until the defective drives are received and inspected by Maxtor: Maxtor RMA facility determined that the drive was damaged by user, and not a defective unit; Maxtor disallowed the RMA replacement warranty. Maxtor did not want to accept back the replacement drives; they had been removed from the sealed-bag and installed. The replacement drives amount was then charged to the credit cards, and “defective†drives returned back to users. Then credit card dispute & charge-back: The credit card charge-backs created a complete hassle with Maxtor to accept the “replacement drives†back and receive full credit.

    Manufacturer with Best RMA Process

    I’ve retuned SCSI drives to: Maxtor Seagate Fujitsu All three have been excellent; no fuss whatsoever. Maxtor shipped brand new replacement drives directly from Malaysia; FedEx 3-day delivery.
  15. I had a similar issue with the Adaptec 39320A-R controller card. After testing several permutations on drive ID the problem persisted. I then changed the SCSI cable with a brand new hi-end SCSI cable and a built-in active terminator and the problem never surfaced again. I am not sure if this may be you cause. Also remember the SCSI controller card’s ID normally defaults to ID 7, but can be manually changed, and could create a problem in ID assignment. Make sure the card’s id is set to 7.
