On the third upgrade of the home nas, I chose http://www.addonics.com/products/raid_system/ae4rcs35nsa.asp to hold the disks. each hold 5 disks, in the space of three slots and 4 fit into a http://www.google.com/search?q=stacker+810 case for a total of 20 disks. But if given a chance to go back in time, the http://www.supermicro.com/products/accessories/mobilerack/CSE-M35TQ.cfm has LEDs next to the drive, and doesn''t vibrate as much. photos in http://rob.com/sun/zfs/ Rob
looks like you used 3 for a total of 15 disks, right? I have a CM stacker too - I used the CM 4-disks-in-3-5.25"-slots though. I am currently trying to sell it too, as it is bulky and I would prefer using eSATA/maybe Firewire/USB enclosures and a small "controller" machine (like a Shuttle) so it is much easier to move around, and much easier to expand. You''ll hit a ceiling real quick with those big chassis (I already did, it only holds 12 disks in current fashion and I have a 16 port Areca card) and I don''t want to get stuck once again running out of space, ZFS or not. Not to mention I had to custom bind two 600w power supplies together to give it enough juice to run... I want something not as.... insane. I just want storage :) On 6/7/07, Rob Logan <Rob at logan.com> wrote:> > On the third upgrade of the home nas, I chose > http://www.addonics.com/products/raid_system/ae4rcs35nsa.asp to hold the > disks. each hold 5 disks, in the space of three slots and 4 fit into a > http://www.google.com/search?q=stacker+810 case for a total of 20 > disks. > > But if given a chance to go back in time, the > http://www.supermicro.com/products/accessories/mobilerack/CSE-M35TQ.cfm > has LEDs next to the drive, and doesn''t vibrate as much. > > photos in http://rob.com/sun/zfs/ > > Rob > _______________________________________________ > zfs-discuss mailing list > zfs-discuss at opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/zfs-discuss >
I only see 15 disks in your CM stacker. I designed and built a system for work with the CMStacker and relocated the power and IO panel from the top slot to the side cover (where the spot for a small fan is) and it works great. A single Seasonic 600AS powers the entire system nicely with PF of 0.98. This unit is designed for small heat signature nearline storage so performance wasn''t a primary factor. With 16x750gb and a Geode-NX processor board the entire system runs right around 253w. I ran into acumulative vibration issues right off the bat and had 3 drive failures within the first 2 months not to mention the slow oscilating drone it produced. taking 2 of the 4 drive carriers and flipping them upside down so that 1/2 the drives were spinning the other direction solved the vibration problem and it''s been running solidly for 2+ years now in near silence. For anyone using more than a single one of these drive sleds, If your data is important to you, I seriously urge you to consider staggering the orientation of them, however ugly it may appear. You''ve been warned ;) -=dave ----- Original Message ----- From: "Rob Logan" <Rob at Logan.com> To: "ZFS discussion list" <zfs-discuss at opensolaris.org> Sent: Thursday, June 07, 2007 10:33 AM Subject: [zfs-discuss] Holding disks for home servers> > On the third upgrade of the home nas, I chose > http://www.addonics.com/products/raid_system/ae4rcs35nsa.asp to hold the > disks. each hold 5 disks, in the space of three slots and 4 fit into a > http://www.google.com/search?q=stacker+810 case for a total of 20 > disks. > > But if given a chance to go back in time, the > http://www.supermicro.com/products/accessories/mobilerack/CSE-M35TQ.cfm > has LEDs next to the drive, and doesn''t vibrate as much. > > photos in http://rob.com/sun/zfs/ > > Rob > _______________________________________________ > zfs-discuss mailing list > zfs-discuss at opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/zfs-discuss >
