Running FreeBSD 5.4... three machines with twe/3ware 8000 and three twa/ 3ware 9500-8 controllers. All of them running RAID 1+0 without write cache since we dont have battery backup unit. All of them Seagate 7200 SATA. I get about 46Mb/s write on the 8000 series and only 5(!)MB/s on the 9500 series. How is this possible? Machines are in production so I can do very little testing... Any ideas?

I recently ran some tests with large sequential writes on a stock 5.4-RC? machine with 4 400GB seagates and a 3ware 9500-12MI. In those tests I got roughly 90 MB/s write on a large raid0 stripe and 66 MB/s on a raid5 setup. I also do not have the battery backup unit. Tweaking the stripe size away from the default made only minor changes. I was also only using a 32 bit pci interface as the motherboard I was testing with didn't have a 64 bit slot. I made no changes to the kernel and even let newfs run with the defaults. That was just a proof of concept run for the larger 9.6 TB 2 9500-12 raid that I'm building tomorrow. I'll let you know if I run into similar problems to yours with multiple cards. -- - Lamont "I am not an atomic playboy."

I have noticed that the MegaRAID SATA cards sometimes disables the write cache on Seagate SATA drives, resulting in a write performance of about 6MB/s. Can you check if the 3ware also does this. I have had arrays were only one disk had write cache disabled and it totally ruined the performance of the whole array. As always be sure to have a good UPS if you are using write cache on the disks! With the sad state of todays ATA/SATA disks turning of write caching in the drive is often not an option. /Martin From owner-freebsd-performance@FreeBSD.ORG Fri May 20 10:06:26 2005 Return-Path: Delivered-To: freebsd-performance@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 2853516A4CF for ; Fri, 20 May 2005 10:06:26 +0000 (GMT) Received: from multiplay.co.uk (www1.multiplay.co.uk [212.42.16.7]) by mx1.FreeBSD.org (Postfix) with ESMTP id EC45C43DC3 for ; Fri, 20 May 2005 10:06:24 +0000 (GMT) (envelope-from killing@multiplay.co.uk) Received: from stevenp4 ([193.123.241.40]) by multiplay.co.uk (multiplay.co.uk [212.42.16.7]) (MDaemon.PRO.v8.0.2.R) with ESMTP id md50001424122.msg for ; Fri, 20 May 2005 11:01:29 +0100 Message-ID: <06aa01c55d23$7a839750$7f06000a@int.mediasurface.com> From: "Steven Hartland" To: "Martin Nilsson" , "Alexis Yushin" References: <20050520031332.GA98548@virgin.ww.net> <428D74E6.4010203@gneto.com> Date: Fri, 20 May 2005 11:05:34 +0100 MIME-Version: 1.0 Content-Type: text/plain; format=flowed; charset="iso-8859-1"; reply-type=response Content-Transfer-Encoding: 7bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 6.00.2900.2527 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2900.2527 X-Spam-Processed: multiplay.co.uk, Fri, 20 May 2005 11:01:29 +0100 (not processed: message from valid local sender) X-MDRemoteIP: 193.123.241.40 X-Return-Path: killing@multiplay.co.uk X-MDaemon-Deliver-To: freebsd-performance@freebsd.org X-MDAV-Processed: multiplay.co.uk, Fri, 20 May 2005 11:01:31 +0100 cc: freebsd-performance@freebsd.org Subject: Re: Bad 3ware 9000 performance 5.4?
