It depends. On your use-case, on your existing system, on your ability to get firmware updates (or at least to check if firmware is one which prevents from 30k/35k/45k hours bug).
If you are after performance: not worth, go used NVME U.2 drives, almost same price for much more power.
If you are after a good performance-powerusage ratio: not worth, go for used enterprise Sata SSDs.
If you have SAS infrastructure in place ( like HBA, backplane and so on) might be worth the money, but I have seen similar Samsungs 1633a for around 150€ even here in Europe.
the ones you have linked come with IBM firmware, imho the worst one to acquire any information or updates. Personally I would avoid them.

Thanks, I've seen NetApp ones (and have access to NetApp FW, but wouldnt know how to update ), but they are sold out atm. Will keep eye out and see if they can be had for under £150 each
I have SAS infrastructure already (Supermicro 24-bay SAS3)

(and have access to NetApp FW, but wouldnt know how to update )

If you have access to the *.lod file, updating them with sg_write is as easy as with any other SAS device. No need to have access to an ONTAP system… just make sure to have them reformatted to 512 before firmware update.

Thank you. Got NA54 and NA55 if anyone requires it

could you please let me know the command to apply the .lod file to a drive? managed to pick one up for £120 (waiting for delivery), but want to test and make sure i can upgrade FW as currently running NA51

 

[mrpasc]

Basically it’s like sudo sg_write_buffer -b 4k -m dmc_offs_save -I file.rel -v /dev/sg1
But of course you must adopt the path to your firmware binary as well the path to your device.

Thanks @mrpasc
Drive was at home when I got back after work. Updated successfully from NA51 to NA54

Nice to read, have fun with those drives.

Might be outside of scope for this thread but... I picked up a 3.84tb netapp branded PM1643a. It's sadly on firmware version NA51. Does anyone have good ideas for where to look for X357_S164A3T8ATE.NA54.LOD? (doesn't appear in the all.zip referenced on page 8)

I have NA54 if you are still looking for it

Was anyone able to update a Samsung branded drive to EQPC?

I recently purchased a P1633N38 from eBay running EQP6 with over 45k hours and I am a little concerned - the drive does not seem to like to be trimmed!

None of Samsung enterprise drives likes trimming. They will hang for about a minute throttling performance to several kilobytes per sec while handling TRIM command. Don't bother, they don't need trimming to demonstrate claimed performance numbers

Ah that is exactly what I have been seeing too - good to know, cheers!

As for firmware, it seems some users have been flashing similar drives with NetApp firmware, but I have not been able to find any posts in this thread regarding doing that with a P1633N38. Is it even possible with this drive?

 

[yukas]

Lovely. At least I can confirm the disks I have have the newest firmware on them. (EQPC)

I'm at a loss as to why they would give firmware out encrypted. To decrypt it, their updater software must have the private key in it. It makes no sense.

Are you able to find the updater application that process the gpg file?

i have decrypted files , but i cant flash to drive - error - pleasee my post https://forums.servethehome.com/ind...2gb-s-mz-ilt3t8a-2-5-289-98.32725/post-391701

Thank you. Got NA54 and NA55 if anyone requires it

Smart says:

Revision: ESFA

Two of the drive labels say:

F/W VFT50Z2Q

So I'm not really sure, TBH.

Update to my earlier post... after formatting to 512, I created a new GPT table and a new partition and now I'm dd'ing the drives to wipe them. I also did a fsck for good measure... which didn't report any problems. Watching dmesg, I haven't seen the errors on the drives for about 3 hours now.

Hi buddy,

I recently got a few PM1643 SSDs with firmware version ESFA， I have reformatted them to 512 format. They're now installed in my DELL T630 server, and everything seems to be running smoothly so far.

Since these drives should be the same model as yours, I would like to ask you a few questions: how long have your drives been running? Do these ESFA drives still have the 32K HOURS BUG or 40K HOURS BUG issue? Any feedback would be greatly appreciated!

I got myself a pair of these drives(SAMSUNG P1633N38 EMC3840EQPCN), but they show as "Unsupported" on my Dell Perc (PERC H730 Adapter FW: 25.4.0.0015) -- the Perc firmware is moderately recent, and I had assumed they'd "just work"... what am I missing?
Even smartctl -d megaraid,X fails to read them. megacli has no trouble finding them, but they show as "Unconfigured(good)"
What option do I have? Is that QPCN firmware affected by the 32k problem?

They may be formatted as 520 bytes/sector. If so, you’ll need a SAS HBA and sgutils to low level format them as 512.

So I finally managed to get the disk formatted to 512 with in an external enclosure, and they seem fine there (and 0% usage on them, so great), but they still fail to be recognized by my raid card! Could it be they are incompatible with 12Gbs cards?
The bizarre thing is that megacli still claim it is 520 sectors, while, it isn't it was formated (and verified) in the other enclosure... SO my guess is that, it's 'guessing'...
