Except for the cable genders, which are reversed. I looked at modding the case to use a standard ATX power supply to reduce the noise only to find out that I would also have to mod all of the internal cables. Certainly do-able, I just didn't get round to it. I opted to replace the case and power supply fans to reduce the noise.ATX power supply
LOL.....Year and half late to the party.My post on these from June 2012 .
They are tempting, have been reported to handle 3TB+ drives and so look like quite a good deal but it is best to check the unit you are going to get as the older gen have metal drive tray latches rather than the pictured plastic ones. Some people have reported getting the older models even though the ebay sale pictures the newer (and much better looking IMO) units.
$500 buys you a MSA600 with dual i/o again !! MANY IN STOCK !! each one has 35 SAS 3gbps slots - tie that up to your MSA or P812 external controller and rock n roll!
You can buy 5 cabinets and do a 10 way raid with 350 4TB RE4 drives for an insanely stupid amount of drives.
Blade owners do this with 2 to 5 cabinets, and zone a drive from each cabinet with a SAS switch from QLOGIC. 70 DRIVES, redundant power (!!!!MUST!!!!) it's back !! i think it has 3 or 4 1200 watt power supplies muahaha
Where the heck are you getting the 70 drive number? No one in their right mind would run that many drives on a single node with those cheap jbods.Look nice.
Anyone know if they come with drive trays or not. 70x drive trays will set people back a pretty packet.
Also SATA II (3Gbps) over 4 SAS cables will bottleneck the drives in certain scenarios.
4 cables x4 lanes per cable x3Gbps = 48Gbps or 6GB/s
6000MB/s split between 70 drives = 85MB/s.
Not a concern for archiving so much but possibly an issue for performance systems.
Still looks like a fantastic deal.
Also note the recommended temps for it are 34c and that, according to the specs, it will shut itself down if it goes over these temps. That may be an issue for me .
EDIT: Seems the seller has more IO modules but at US$655 each.
Read the advert, read the specs, read the manual. Oh heck I will save you the effort.Where the heck are you getting the 70 drive number? No one in their right mind would run that many drives on a single node with those cheap jbods.
The unit has 70 drive bays spread over two draws. That is where I got the 70 drive from. Sort of hard to miss really.HHp StorageWorks Modular Disk System 600 with two Dual Port I/O Module System - Hard drive array - 70 bays ( SATA-300 / SAS ) - 0 x HD - Serial Attached SCSI (external) - rack-mountable - 5U -
