I come to the hardware from the perspective of a database-developer; how do I break 100k TPS? How do I break 10GB/sec? These questions lead me back to the hardware, and videos like this have helped cement the notion I'm on the right track. Cheers and thank-you.

If your vdevs are mirrored, you can spread the disks across the two HBAs to gain some redundancy that way also.

The Dell Perc h200 is also a good cheap raid card which can be flashed as a HBA
@vewo2344 жыл бұрын
I have several of the Dell PERC H310 cards running in HBA (IT) mode. These are the same as the popular IBM M1015 but have the SAS connectors at the short side opposite of the slot bracket. So they can be used in height restricting cases easier and would not have caused the cable length issue shown in the video. 😉 With some luck you get the card with both the full and half height bracket included on ebay.

Flashing these cards is easy, you can flash back too, I run 8 SAS drives on mine, they run both SAS and SATA with the correct cables....brilliant cards in my opinion. I install them into NAS boxes, they are visible in synology, VMware, freenas amd xpenology.

It wouldn't be a bad idea to put a fan on the heat sink on the SAS control card. I have an HP server that has support for both SATA 3 and SAS type drives, but I use the SATA drives. I also use Toshiba NAS HDD's they are very cheaply priced for the quality. Even cheaper than Segate and I have had some problems with Segate drives so I use WD Gold, Red or the Raptor type HDD's if I go mechanical rather than SSD.

Any problems with those SATA connectors staying snug? I noticed that cable doesn't seem to have metal clips on the SATA connectors. I hastily bid on and won a similar cable on ebay (3ft, longer than I need) and just noticed it doesn't have the clips either. Hopefully it's works ok.

I have been searching for a SATA SAS and found some older cards PCI-e 8X made for 1st & 2nd generation PCI-e slots 12 years old. Is there anything newer with built in memory cache and battery backup for the SAS cards only so I don't loose a RAID or acidentally drop a drive from power surges or losses. I will most likely use Windows 10 or 11. and or Ubuntu 20.4 P.S Loved your video looking for more so I "Subscribed ", clicked the "Bell" and chose "ALL" hoping to see more videos from you.

Those cards are expensive, but they are server grade, and hardly EVER fail. Theyre's a reason why they are expensive. Server grade cards need to be able to operate 24/7 and not fail when moving around lots of data on RAID arrays, like the LSI i have in my fileserver. That was very nice of her to give u that. It should last you quite a LONG time.

basically same hw as mine 9220-8i. I just installed LSI MR SAS 9260-8i (yes MR stands for MegaRAID) with full feature set (RAID5, RAID6 and SSD caching enabled). I would be using it for RAID6 as RAID6 over BTRFS is unsafe, but BTRFS over RAID6 is double safe (double parity on RAID6 plus checksums on BTRFS)

I haven't played about with ZFS for well over 8 years as RAID10 via my (AMD/Promise) motherboard's SATA controller was giving me much better sequential performance than ZFS, the ZFS gurus with high performing systems seem to require a sperate PC/Server with 64GB+ of RAM to get this level of performance, at the time 64GB+ RAM was a pipe dream for me let alone the expense of running a separate system. I'm a Windows Server guy (know a bit about Linux too) I run a single Windows Hypev-V Server as my Storage and Virtualisation (home lab) platform and to this day second hand RAID controllers (Mainly Adaptec in my case) have been the way to go. Lastly I work with SANs Netapp, 3PAR etc.. personally I don't believe that "Server" disks (Excluding SSDs) are significantly better life time wise than Desktop Disks, certainly not the 15K SAS versions. Its the better (loud) cooling and PSUs in Server/SAN kit that might give the impression higher reliability. Lastly I'd bet the SATA card would last at least as long LSI HBA, as one prolonged fan failure and the HBA might be toast, RAID and HBA cards/controllers require active cooling the SATA card doesn't... basically I wouldn't believe a lot of the marketing hype when it comes to enterprise reliability.

It depends on whether the files are in cache or not. The best sequential reads from the disks are about 800MB/s. If the files are in cache, its limited by the network (about 12GB/s).

So when an HBA like the following "supports up to 240 devices as a HBA in IT mode", how exactly do you attach 240 devices? From what I've found you can only use a forward-breakout cable in one layer. So for 4 "ports" I can only get 16 devices. Surely there is a way to at least double this... www.supermicro.com/en/products/accessories/addon/AOC-S3216L-L16iT.php
