M on the way. Aimed at high performance and high availability applications, they tend to have more ports, cache, perhaps battery for the cache, and options for managing and configuring the array. Directly attached drives look just about the same, just fewer of them: Confused about that LSI card? If you have one already I’d try it and post back. View attachment Within FreeBSD, that’ll probe as a controller serviced by the mps driver, and the drives will appear as normal “daX” devices and appear in “camcontrol devlist”, so pretty straightforward pleasure there.

A “dmesg grep mps” would show something like: Aimed at high performance freebd high availability applications, they tend to have more ports, cache, perhaps battery for the cache, and options for managing and configuring the array.

LSI SAS mps driver preferred firmware version
View attachment Shows you the adapter type and firmware revision. View attachment And so far, things like hot adding a drive seem to work fine. Sent from my iPhone using Tapatalk freebsx. Actually for LSI cards you can make a DOS bootable using freevsd old USB thumb drive with the firmware files on it and slip that into your uber Unix box and boot it up and do the firmware work without messing up your nice unix box.
View attachment You can hit control-C during that to get to the card configuration utility. The error seems to manifest on certain Intel chipsets. These devices are intended to abstract out the physical storage and present the system with virtual devices, which means freebsr they’ve got an incredibly flexible and rich featureset and the ability to attach lots of drives both directly and indirectly, in many RAID levels, etc.
Joined Mar 25, Messages 19, Thanks 1, It’s totally unrealistic to require Windows in order to update firmware on a network frrebsd storage controller, because you’re not going to install Windows on your massive UNIX server just to update some firmware.
But that’s not really what you want for FreeNAS. If you do, it works under the “mps” driver, and it becomes a plain HBA. freebse
Freebss cards often come without brackets or with a low-profile bracket to fit into 2U rackmount servers. Thank You for the education. The card consumes around 10 watts and should have at least some airflow in order to maintain proper cooling.
They’re not hopeless, but the inexpensive HBA models are more appropriate and better suited to the task. As per the readme make sure you use firmware version Status Not open for further replies. If you’re confused, it is probably understandable Joined Dec 3, Messages Thanks 7.
LSI SAS HBAs (mps) utility
Once the M was flashed to IT mode, I was able to place the card back into the intended machine and use it with out issue. Sure, it’s “newer” but it won’t affect the performance of ZFS In some cases, users have come to the forum inquiring about a many-port controller where some combination would do.
Any use of “virtual drives” or one-drive RAID0 JBOD modes likely involves the controller writing its own proprietary configuration to the drive and then that means that if you ever need to switch controllers, you’re going to have extra special trouble because you need to copy the data off the old drive, not just move the old drive to a new SATA controller port. But if you’re stuck with an LSI RAID controller, here’s some hopefully helpful information because you’re probably sitting there wondering “what now.
