Thanks for your answer.
I asked primarily because of the mpt timeout issues I
saw on the list.
Hi Arnaud,
I am looking into the LSI SAS 3081 as well. My current understanding
with mpt issues is that the "sticky" part of these problems is rather
related to multipath features, that is using port multipliers or sas
> expanders. Avoiding these one should be fine.
I am quite a newbie though. Just judging from what I read here.
I do not think that you are reading the data correctly.
The issues that we have seen via this list and storage-discuss
have implicated downrev firmware on cards, and the various different
disk drives that people choose to attach to those cards.
The use of SAS expanders with mpt-based cards is *not* an issue.
The use of MPxIO with mpt-based cards is *not* an issue.
Both MPxIO and SAS Expanders are an essential part of the whole
picture that is the SS7000 appliance series, as well as the
J4x00 series.
Personally, I'm quite happy with the LSISAS3081E that I have
installed in my system, with the attached 320Gb consumer-grade
SATA2 disks.
