What you describe is what we do already: we boot locally and we have the
larger volumes on fibre channel. Having said that, we are back to square one. We want to boot the local volume of a W8000 workstation from the Compaq 15K 9GB drive in the SCSI ID=0 position inside a Compaq 4214R case. We cannot get the drive to autostart when connected to the W8000. -- Will westes AT earthbroadcast.com "Nut Cracker" wrote in message ... The 4000 and the 4100 use an identical in-chassis controller (which uses the 64M BBC that the SA3200 uses, which can also be used to give a 2DH 64M cache as well). The difference is in the drive support. The 4000 supports WUS3 drives, while the 4100 supports the U2/U3 drives and trays. As for HBA's, I have had limited sucess with the Emuex PL7000e controllers, while every single time I have used the CPQ FCAL PCI Adapter ( http://tinyurl.com/34wa2) I have had no problems at all. Honestly thought, my testing has yielded that this controller is only capable of about 256 I/O's a second, and as such is not the best performing card I have used. (sorry about the bold text.. cant make it go away...) I have not played around with making the HBA the first controller on the servers I have, as I have been under the impression it was not an option anyway. However, if you were to put an 18 or 36G U2, 68pin drive on the internal controller for booting, and then having the data volume be on the SAN, you would achieve a vast majority of your storage goal. "CHANGE USERNAME TO westes" wrote in message ... We use the RA4000, but we have never found any way to boot a Windows 2000 computer from one, using any fibre channel host adapter. Compaq is using some weird very proprietary fibre channel variant on those boxes, and they refuse to give us any details. I cannot get anything except a handful of Compaq adapters to work with logical devices created on the RA4000. Maybe the RA4100 is different? -- Will westes AT earthbroadcast.com "NuTCrAcKeR" wrote in message news ebay is your friend. I wasnt suggesting SAN booting the workstations, thought that is a thought. If you are patient, you can build an economical SAN with Hpaq gear. You can get an RA4000/R4100 for next to nothing. The adapters are always being listed, as are the hubs and switches. SC-SC cables can also be found. Plus, the RA series uses standard SCSI drives, so you dont have to muck with FC drives and all that. Depending on the number of workstations you are planning on outfitting, $1500 ~ $2000 should get you outfitted with at least 1TB across a few chassis. And, if you have version 2.60 on the RA firmware, you can do SSP (selective storage presentation) at the RA-Controller level. You could also get one of the OEM brocade switches (not "modular data router") which can also take care of the presentation for you, and probably with better performance. So, how cheap is cheap ? and how much space makes it worth it ? - LC "CHANGE USERNAME TO westes" wrote in message ... We used to attach it to a Compaq UW. We removed that and want to replace that with the 4214R. So one machine with one external interface attached to one external cabinet. I'll do more experiments later today and post results. I'm with you as far as fibre channel goes. I would love to be booting our workstations off of fibre drives and have those consolidated in location to a central room, which would lower noise as well. The problem is how to do this on the cheap. The cheap fibre cabinets are the Compaq fibre channel arrays. The problem is the standard Compaq 32 and 64 bit fibre channel adapters that work with those products do NOT allow you to boot from the array! I understand that later generations of the host adapter do allow this, but those adapters cost as much as the workstation does. Do you know of anyone who makes a JBOD fibre cabinet that: A) has some simple firewall capabilities, so we can control which hosts see which drives. B) is relatively cheap, and preferably plentiful on the secondary market -- Will westes AT earthbroadcast.com "NuTCrAcKeR" wrote in message ... Ok... Hrmm, W8000 on board controller. If i am not mistaken, the onboard controller has only one external header. how are you attaching 2 cabinets to this machine ? Is the UW hanging off the external, and the New chassis coming off the internal header by way of a redirection cable ? Throw me a bone here, and give me some information. Surgically extracting every piece of information from you is getting quite tedious, and boring. A better, more affordable architecture might be to put a fibre channel HBA in each machine, put those pluggable cabinets to some real use by building a workgroup SAN. They (workstations) will have the added benefit of RAID, and take advantage of the availabilility features that are being thoroughly wasted in their current capacity. -LC "CHANGE USERNAME TO westes" wrote in message ... The same W8000 is currently attached to a Compaq UW case, and those drives start up just fine, so the system is configured to autostart the drives. The cabinet is attached to the machine when it is powered on. The computer is powered on after the case is powered on. Using the Compaq W8000 onboard controller. -- Will westes AT earthbroadcast.com "NuTCrAcKeR" wrote in message ... typically, one wouldnt need to change it. So, is the cabinet attached to a machine when you power it on? On board controller with the PWS, or a diff HPaq or 3rd party ? Which one, and is it configured to send the start command to the systems. have you tried hanging this off a workstation in the same configuration that you know is operational ? troubleshooting is a process of elimination... - LC |

why have the local drive in a chassis? its just 1 drive. use it internally,
and string from the internal SCSI header. - LC "CHANGE USERNAME TO westes" wrote in message ...

Thank you Guy, its always nice to know that others are watching and gleaning
something from the discussion. - LC "Guy Macon" http://www.guymacon.com wrote in message ... I just wanted to mention that I find this thread to be informative, even though I have nothing to contribute. |

A lifetime of opening cases, unscrewing hard drive, unplugging 68 pin
connectors, etc, has convinced me that hotswap is the way to go. It saves me time, and time is money. We get huge leverage from being able to take any end user's drive out of his case and examine it and fix it on any other machine. -- Will westes AT earthbroadcast.com "Nut Cracker" wrote in message ... why have the local drive in a chassis? its just 1 drive. use it internally, and string from the internal SCSI header. - LC |

Surely there are many ways to achieve the same thing with the workstation,
without introducing a heater and acustic enhancer to a users desk. Those things ARE annoyingly loud. They may not be HPaq branded solutions, per se... but they certainly are doable. - LC "CHANGE USERNAME TO westes" wrote in message ...
