Too bad about USB-C charging, though.

As long as AMD has comparable segment solutions that support ECC memory that would be my choice.

What would you do? Can't make up my mind. I need to add storage and the physical location question - what kind of enclosure - is killing me. Traditionally, my storage comes in three tiers: My main workstation has a 5-disk SATA frame for data the workstation works on. This functions very well...

Thanks so much, rubylaser.

Well I needed the full block of lspci. But I have figured it out. I have my own kernel, a variant of 4.4.3 and got confused about mptsas, mpt2sas and mpt3sas, the middle one having been removed but aliased. Anyway: 02:00.0 Serial Attached SCSI controller: LSI Logic / Symbios Logic SAS2008...

Oh wait. Me dumb. `sudo lspci -v` the section for the LSI please? I think I am completely mislead by loading an incorrect driver but it outputting messages confusing me. And which kernel version do you have there?

I'm strongly in the software raid camp. Let's leave aside post-RAID like ZFS's which is more complicated but clearly not hardware raid. Let's stick with traditional raid that has no idea what the filesystem is doing, that has the raid hole etc. My reasons for liking software raid like Linux'...

Short version: Can somebody who has a LSI SAS2008 or similar running in JBOD mode in Linux send me the output of the relevant `lsmod` parts, `dmesg` or whatever could help? Long version: I have this SAS2008. Its BIOS clearly says it has "IT" in the software, as in the name, there is no...

A slow link between two large filesystems that you want to keep in sync is a prime use for sendfile/receivefile snapshots. ZFS does, I think BTRFS does, too. That would allow for very high frequencies of syncs without overloading either the link or the filesystem. If you used rsync instead you...

Might be pointless to have ECC RAM if you then use a NVidia GPU which does not.

Excuse my ignorance but given that these are not CAT6, why would I pick them over Infiniband?

I think the attractive solutions these days are: - Linux md + ext4fs. Only up to raid6. Very robust. No features - Linux md + btrfs. Maybe less robust in the FS layer but still robust in the raid layer. Adds snapshots and offline dedup. - Linux, FreeBSD or Solaris + ZFS. Theoretically better...

I strongly feel smug about dual 1366 for ZFS. You will really appreciate large amounts of RAM. A platform with 12 or 18 RAM slots that all take registered RAM is cheap for 1366, as are CPUs, and you don't have to bother with extra special CPUs to get them cheap. The unusual amount of RAM...

I use the Toshis, too. One out of 7 had minimal read errors at some point in a few years so I moved it to a secondary array. But after a full overwrite it never made a muck again over there.

Duno. ST3000DM001-9YN1 I'm not bothering with learning Seagateish anymore :)
