The drives never even show up to the raid card. If I plug a SAS drive in they do though, but a SATA isn't even detected. The controller in the DAS detects them though. I have hooked a serial cable to it and any SATA I plug in shows failed right off the bat. Its almost like a setting in the DAS is denying the use of SATA drives...What raid card are you using? If it's lsi try to mark the drives good and see if it will take them. I have noticed this happens sometimes with lsi cards
I'm using it with SATA drives. I have 3 of them at home and they work great. Can't use the 2nd controller on the back tho as SATA drives only have 1 channel. It just shows errors. But it works great. Easily best DAS for home use for the price.do the front bay work with SATA drives?
I'm running 12 6TB WD REDs. You won't be able to run multiple IO modules unless you run SAS drives as the 2nd IO module doesn't see the drives or shows errors. I can't remember when I checked it out. They work fine with my drives though. I'm using a Dell H830 controller currently. Thinking of spending the money on a damn Lenovo controller though as I can't turn the freakin fans down without one and its loud as hell.Has anyone tried to use HDDs bigger than 4TB? Will SA120 work with 6TB SATA drives? I'm interested in using HGST Ultrastar 7K6000 6Tb but would like to be sure before spending money.
And what JBOD SAS\SATA3 controller (HBA without RAID) would be suitable for Intel HNS2600JFQ? Is LSI 9200-8e good enough?
If using 8 ports (2x4) controller and double IO modules JBOD will it give more throughput? Manual says that it is for redundancy but High Availability Guide also points to speed enhancement. Should it be manually configured to two groups of drives for two IO modules or it happens automatically when the second IO module connects to the HBA controller?
Thanks!
Thanks for the information! May be it has a sense to change 7K600 SATA to SAS... Price difference is only $20-25 for 6TB model as far as I can see.You won't be able to run multiple IO modules unless you run SAS drives as the 2nd IO module doesn't see the drives or shows errors. I can't remember when I checked it out.
Truthfully, I have no idea why man. I do know I got 3 with redundant IO modules and power suppliers for like $300 shipped off ebay brand new in the box. They don't come with the 2.5 cages that fit in the back but if you look you can get them cheap sometimes.Am I missing something? Why are these DAS arrays so cheap compared to other SAN arrays, such as the HP MSA 2040?
Lenovo was handing out huge cash-back incentives on these. Similar to TS140/TS440/TD340...$300 is absolutely not SRP for those.Am I missing something? Why are these DAS arrays so cheap compared to other SAN arrays, such as the HP MSA 2040?
DAS=Direct Attached Storage i.e. Drive tray hooked into another server/system that then controls the drivesIs there a different in a DAS and SAN? The MSAs I have used have all been fiber channel directly connected to a server
So in this instance, what would be the difference between this device, and the MSA 2040 with its controllers connected directly via fiber channel to a DL380?DAS=Direct Attached Storage i.e. Drive tray hooked into another server/system that then controls the drives
SAN = Storage Area Network i.e. System with Disks that has a network connection that controls all the drives internally (usually)
Had a colleague buy one of these and I was wondering if anyone knew of a GOOD external SAS pci-express card and cable to go along with them?
Long Story Short:So in this instance, what would be the difference between this device, and the MSA 2040 with its controllers connected directly via fiber channel to a DL380?
The main difference is that DAS can be attached only directly to the head unit (server). SAN devices can be attached directly to server and through switch devices. But novadays this classification often doesn't reflect actual state of thigs: there are a number of SAS switches on the market so even this particular device theoretically can be marked as SAN device.Is there a different in a DAS and SAN?
