    What's the maximum safe temperature? I'm showing 52C idle and 65C under load. Do I need a fan?

    IBM DAS with 12x1tb HDD.

    I was in the market for a disk shelf. Lenovo SA120 would be preferable, but is like $500 by the time you buy caddies. I just didn't expect this to be a SAS1 expander. Is SAS1 that bad?

    I bought three... please tell me this was a good financial decision.

    IBM DAS with 12x1tb HDD.

    I think the eBay description was wrong - these use SAS1 expanders at 3Gb/s not 6Gb/s. See my other post here: https://forums.servethehome.com/index.php?threads/lsi-sas9200-16e-slow-performance-using-8-drives.27454/ I'm new to DAS hardware so am not sure whether this is acceptable.

    IBM DAS with 12x1tb HDD.

    Is there any practical way to upgrade the SAS controller to upgrade these from SAS 3Gb/s to SAS 6Gb/s? Or is that even necessary for spinning rust drives?

    LSI SAS9200-16E -- Slow Performance Using 8+ Drives

    Thanks for your patience. I am obviously still learning, and have much more to learn. The DAS has two ESM modules. Each ESM has two ports (one IN and one OUT, like you mentioned). Is it possible to run two cables to the DAS to double throughput? HBA Port #1 ==> DAS ECM #1 (IN) HBA Port...

    LSI SAS9200-16E -- Slow Performance Using 8+ Drives

    Now I'm really scratching my head. Any clues? EBay listing shows 6GB/s (which obviously isn't trustworthy). However IBM's website contemplates both 3 and 6GB/s speeds. Also from IBM's website: IBM - IBM System Storage EXP3000 Express - Specifications - Model 1727-01X—IBM System Storage®...

    IBM DAS with 12x1tb HDD.

    I don't think a 47 ohm resistor would do anything. The fan is 12Vdc at 2.95 Amp. Assuming the "normal" operating voltage is 9Vdc at 900 mA, then I think we would need a 2 ohm resistor capable of dissipating a little over 1W. Do you agree? I can't seem to find anything on ebay with that...

    LSI SAS9200-16E -- Slow Performance Using 8+ Drives

    Thanks. Sorry for being thick, but which part is a 3gb/s expander - the DAS or the LSI card? The DAS is supposed to have two 6gb/s ESMs.

    LSI SAS9200-16E -- Slow Performance Using 8+ Drives

    Overview: My LSI card in IT mode tends to slow when more than 8 drives are being utilized. Is this normal behavior? Hardware: LSI SAS9200-16E https://www.ebay.com/itm/LSI-SAS9200-16E-16-PORTS-6GB-S-SAS-PCI-E-CONTROLLER/113983567356?ssPageName=STRK:MEBIDX:IT&_trksid=p2060353.m2763.l2649 FW...
