Re: searching raid 6 card working with fedora 23

I think i misunderstood what you guys said about jbod (my fault for reading quickly), i talked about the jbod feature, not a hardware piece.
My disks are sitting in my desktop, if i buy an external storage for the disks i might as well build a nas, which is what i do not want, i'm looking for internal connection not external.

was crawlking lsi and highpoint cards, cards between 200 to 300+$$, not really what i call cheaper stuff that's aimed at Winblows users ;)

@roberto : would love to but i can't. I have only 3 sata ports available

I don't have any choice here, either i buy a compatible raid card or a
hba card (or buying an expensive nas lol)

@gordon : The number of atx motherboard dedicated to gamers with ecc
compatibility is close to none.
Since i am no exception (no ecc support) i will not change my
motherboard for this, never had an issue and i had  3+ To of datas for
almost 5years, would be pointless to change my motherboard now anyway
since i'm waiting for kubylake.
The basic consumer just follow the trend, if constructors don't feel
like we need it they won't put us fancy features.

I'll look at your links thanks. Already did look for specific chipset
that are good with zfs but almost every list is too old, seems that
every time a brand is building something that works they don't change it
for like 10years or something.

Ah ! That's how you call it in english, didn't know, well that's what
i'm looking for, already have the mini-sas to sata cable.
I'm talking about passing your disks as jbod with an hba card, since you
will not rely on some hardware card ram and processor my logic (and some
tests i found online) tells me it will be faster.

@rick : was looking for hba already but everytime i find a good card i
have to mail the tech support of the constructor to check if it will run
with my kernel, such a pain...

If you stick with one of the "major players" (e.g. Dell, HP, IBM,
Adaptec, Emulex) and you're willing to pay a bit more, you'll probably
be just fine. Example:

http://accessories.dell.com/sna/productdetail.aspx?c=us&l=en&s=dhs&cs=19&sku=342-0910

6Gbps dual-port SAS2 HBA, about $200 US, and I can pretty much guarantee it'll work with your kernel. Couple that to a JBOD and some drives and you're good to go.

If you stick with the cheaper stuff that's aimed at Winblows users,
you'll have a much harder time. While you may not think of it this way,
you're encroaching on "SOHO" (small home and office) territory, at least
as far as the manufacturers are concerned, and that's sorta where you
have to look.

I'd suggest spending your money on a decent HBA, and prowl eBay for
a JBOD (there's lots out there and on the used market, they're rather
cheap). The JBOD itself isn't a big deal--as long as it's compatible
with your HBA. The drives you use IN the JBOD are important.

Just my $0.02. It's your data, you know how secure you need it and what
you can spend.

        I think I'm talking about the cases you mentioned in an earlier
        email. A
        lot of HBAs have a single cable connection, such as a mini-SAS
        connection, that connects to a board (a backplane) that sits at
        the back
        of the drive bays, on which the power and data connections for the
        drives are mounted.


    Otherwise known as a JBOD ("just a bunch of disks"). There are tons of
    JBODs out there. Google search for "JBOD" or "storage arrays". I even
    see an HP enclosure for $250 US from HardDrives Direct.
