This is the maxtor information that I have. I am sending this out because I have had troubles trying to feed it through various mailers in response to requests. Anyway, all this is is a concatenated list of answers to a query I made about various experiences with the maxtor 320 mbyte drive with the emulex controller. All were favorable, and light of this, we have decided to buy one for our microvax. -Ike. =========================================================================== Return-Path: @SRI-KL.ARPA:SYSMGR%nuhub.acs.northeastern.edu@RELAY.CS.NET Date: Tue, 27 Jan 87 09:32 EST From: SYSMGR%nuhub.acs.northeastern.edu@RELAY.CS.NET To: @SRI-KL.ARPA:monkey@ATHENA.MIT.EDU Mmdf-Warning: Parse error in original version of preceding line at RELAY.CS.NET Subject: RE: Emulex Maxtor drives X-Vms-To: NET%"@SRI-KL.ARPA:monkey@ATHENA.MIT.EDU",SYSMGR We installed a Maxtor EXT-4380 drive packaged with a Emulex QD-21 controller into a Microvax II BA123 box.

We've had one since June 1986 and it's been largely trouble free. Since the system was installed, we've had about 10 disk errors, all correctable. Most of these came within the first few months, and one additional media check by the Emulex diagnostic program made all those go away. It's also faster than an RD53 and costs about 1/2 as much per block of storage. It has only one drawback though, it is noisy. You can tell how busy it is with your eyes closed.

Cost-wise, your best bet is to buy an Emulex controller (if that is what you) want) and the disk drive - all from a third party. greg pavlov, fstrf, amherst, ny =========================================================================== Return-Path: bobp%tektools.tek.com@RELAY.CS.NET Date: Wed, 28 Jan 87 08:52:59 PST From: "Robert N.

Other than a couple of infant mortality cases we have had absolutely NO problems with any of them. They are a dream. This says a lot for DEC's MSCP protocol. These devices are actually faster than the RA-81's. I think EMULEX just dropped the price of their EMS-380 systems,too.

No problems at all under VMS -- it is our ONLY disk on that machine, mapped to look like 2 or 3 (I forget) separate volumes. On the other MicroVAX we run Unix 4.3 bsd from Mt. Xinu, and there is some problem with getting that operating system to recognize the Maxtor. Either Webster was not complete in their emulation of a DEC controller, or Mt Xinu did a poor implementation which depends on DEC-specific disk sizes or something like that. Something to be cautious about if you run Unix -- any Emulex product will almost certainly run fine under VMS. We have very good experience with Emulex products -- a low-end tape drive, a 600 Mbyte disk, and a serial communications multiplexer, all plugged into our 750. Good luck.

It works great. It was kind of tough to install, at least that's what the DEC service guy claimed. He hacked around quite a while at it (he was here to fix the tk-50 drive and had time left on his service call, so he voluntered to put in the controller and drive). He got that sucker installed and it's been trouble free.

The latter is the EMS/380 subsystem purchased from and installed by Emulex, and consists of a Maxtor 5 1/4" Winchester disk that formats to about 320 MB, and QD21 controller by Emulex. Current GSA-discounted price from Emulex is about $5000 for the disk and around $400 to install. We have had ours running for several months, with virtually no problems. We've made the RD53 our system disk, and the Maxtor is our public disk. VMS seems perfectly content. After several conversations with our local DEC Field Service person, we have gotten the word that this product is to be officially supported by DEC, and have arranged DEC maintenance ($124/mo BMC). - Norm Sutherland - ===========================================================================
