I need to connect 4 SED Ultrastar HC550 hard drives somehow, but I don't know what to look for other than low price and number of ports. The drives are less than 285 MB/s each, so I doubt there would be bandwidth limitations. Does the HBA affect use of TCG Enterprise encryption? I was looking at...

Hello, so, I am trying to figure out if I understand ZFS and how I should go about setting up TrueNAS. My current hardware is A dell poweredge R720XD, that has 2 SATA boot SSDs on the rear backplane in one mirror and then 24 drive bays in the front I intend to populate with 1TB SAS drives. I was...

So, Recently I picked up a dell R720XD for a good deal, and I am waiting for my drives to come in to use it as a home NAS. I planned on using truenas with a raidz2 setup using Dell SAS drives and to boot off a raid1 setup using the rear back-plane on the 720xd for a pair of SATA SSDs. In doing...

To my surprise LVM mdadm does actually seem to be able to save extra checksum-data to prevent bit-rot/soft corruption. Until now I thought the only way was to go e.g. btrfs or sfz. But I just ran into this article over at RHEL: Using DM integrity with RAID LV Together with thin LVM snapshots...

I am very new to RAID/HBA cards and to flashing them. I read through nearly all big guides (e.g. techmattr, etc.) on how to flash this card to IT mode. The files I used for flashing are from a link to a zip-folder provided in techmattr's guide (folder date: 2016-05-24) I have provided...

I have an old HP N40L MicroServer that is still going strong, right now running FreeNAS 11.3. I just replaced the drives in it (and am resilvering the last one as I write this) after one failed and decided to start thinking about what other upgrades I could do to extend its useful life a bit...

The work load consists of generating many files as fast as possible on very fast storage, (RAID 0 of nvme drives) and transferring that data to slow storage for long term storage while minimizing the bottleneck. I'm trying to minimize the time limit for the transfers to long term storage. When...

Hi folks, I have a custom built dual Xeon workstation on a Supermicro X10DRI mobo and am now trying to pick a SAS controller for future HDD expandability. My best option for my budget for now is an LSI 9261-8I 512 MB and because the HP P420 comes at a good price, I wanted to ask whether...
