Planning my NAS migration from DS223 to DS1621+

Pulled the plug on the bigger NAS (DS1621+). I could see the DS223 was not going to suffice over the long haul for my image and video editing and backup. With the DS1621+, I also ordered one more 12TB Seagate Ironwolf, and 2- 1TB M.2 2280 PCIe (4.0 x4) NVMe Solid State Drives for the SSD Cache. My current plan is…

  1. Power off DS223 and let drives spin down.
  2. Move the 2-12TB drives from the DS223 over to the DS1621+.
  3. Power up the new NAS and go through the migration for the two drives.
  4. Power down new NAS, remove the drives, and install the 2-SSD’s in the cache slots.
  5. Power up and complete the cache setup.
  6. Power off the NAS and install the new 12TB drive (for a total of 3 active drives)
  7. Power on the NAS and configure the new additional drive.

Would imagine you could go in either order - install SSD for cache, then the new 12TB drive, or vise versa?

How does the plan sound? Any flaws in the logic I need to correct?

The current drive setup in the DS223 is the SHR RAID config. Once I get everything moved to the DS1621+, and install the additional 12TB drive, do I want to continue that kind of RAID? Or, do I want to change it to a different configuration? Is that even possible without loosing data?

Looks like the DS1621+ has several RJ-45 ports. One will be used to connect to my cable modem. The other three are for what? Is there any way to stay connected to the cable modem, but also have a direct connect to the iMac? Thanks!

I can’t comment on the process you are following but consider getting a 10 or 25gb ethernet adapter for a much faster response time. It’s an add on but well worth it.

Search the SpaceRex videos on how to make that direct connection. I think there is one.

I think you are referring to this video: Setting up a 10GbE Synology WITHOUT a 10GbE Switch

You can certainly go with cheaper models than OWC on Amazon. For example SABRENT offers three models (10 gbps, 5 gbps, and 2.5 gbps) on Amazon.

Right; although it’s hard to sort out whether there are driver issues or not. Just the speed difference is huge. For the Synology though you need to buy their adapter.

My current setup is an SHR RAID. Once I’m moved to the new NAS and add another 12TB drive, do I want to continue the SHR? Or, is there a better RAID setup I should consider? Thx

So far so good. Both 12TB drives moved over to the “new” DS1621+ from the “old” DS223. Two 1TB SSD’s installed and setup as cache. Numerous setup/config items completed. Today I hot installed a new 12TB drive and am now letting the RAID incorporate it into the pool (looks like an all weekend thing).

I was pleasantly surprise (understatement!) that the DS1621+ so readily incorporated my two data drives and seemingly embraced the various data structures I had on them. When I opened up Lightroom and it read from the NAS it was like just before. And the previews snapped into place very nicely. I was also able to launch a Final Cut library directly from the NAS via Finder, and the video timeline was very snappy.

Praying now for a successful pool update.:slight_smile:

Whew! :grin: :tada: :zap: :boom:

I didn’t know that you can move formatted drive to a new machine and incorporate them without the drives getting reformatted. That’s the first time I’ve heard that. Good to know.

I just had a crashed DS1522+ named DS01 (mainboard died with blown capacitor).
The same customer had a second DS1522+ for off-site backups. As this off-site device is not mission critical we can without it for a short period.

I stripped the drives from both stations and inserted the drives from unit #1(dead) into unit #2(offsite).
The off-site dics will be inserted in a new deveice that will arrive in 1-2 days.

I booted unit#2 with discs of unit#1 and it became unit #1 - no actions needed, it just booted right from the start as unit#1

DSM had the idential settings - most importantly unit #1 device name and IP address #1 were migrated. Since we did not have a IP reservation on the Windows Domain Controller Unit#2 was instantly accessible for endusers with IP as per the network setting of Unit#1. This lead to a still working Active Directory binding - so all folder permissions were instantly instanct & available. → UNC path and credentials of Unit#1 are all working and the users had almost not down time.

Obviously I could have done a failover with Snapshot Replication but we would have lost the work between since the last replication (You can do a lot of work in 15min :wink: ). If you have idential/similar devices at hand this is really the easiest way to go

(NVMe only for ready caches, no write caches!!, check the file logs for the last entries so users can check if their data is corrupt, do not put transaction logs and database file in the same basket)
