Migrating from HS-251+ with UX-800P

[zylch]

Dear QNAP community,

I am a newbie and looking for advice on upgrading my current configuration. This is my current setup:

- HS-251+ NAS with 2 x 6 TB drives in RAID 1 configuration (Storage Pool 1, 78% used)
- UX-800P expansion unit with 8 x 6 TB drives in RAID 5 configuration (Storage Pool 2, 93% used)

My problem is that:
1) I am approaching full capacity on both the NAS and the expansion unit.
2) The current configuration makes it almost impossible for me to backup the content, since only 1 expansion unit can be attached to the HS-251+ and it would be extremely impractical to have to manually backup to individual external HDDs. I am getting more and more nervous about losing all my data, as I have no backups and feel my current RAID 5 configuration does not offer enough protection.

I thought of migrating my HS-251+to a new NAS with more bays and capable of accepting 2 expansion units, then adding an extra UX-800P. This would solve the capacity issue but still not the backup problem. I have a couple of questions about this:
- I know I can migrate to various NAS by swapping the disks, but will my current UX-800P content be recognised by the new NAS after migrating?
- If that's the case, can I then configure the new UX-800P with the current one as RAID 6, to increase the capacity while offering some added protection?

To solve the backup issue, I guess I could keep my current HS-251+ with it's UX-800P to backup some of the new system, so I would end up:
- New NAS with 2 new UX-800Ps
- HS-251+ with UX-800P for backup

Any thoughts or guidance would be highly appreciated!

x73 or above
REXP-1000 Pro, up to 4 units possible

throughput should be same or near same as host

Thanks, I hadn't considered the REXP-1000 Pro.
For the purpose of the migration, would I be able to plug my current UX-800P into the new system withouth losing all the data on it?

[kherr4377]

if the NAS you choose supports the UX, i would think you could plug into it and transfer. or transfer over the network, if nothing else. i wouldn't think the transfer rate would be all that great because of the UX. you would probably make a RTRR job or something to do it.

I need to know for sure whether I'd be able to migrate the UX to the new NAS, because if that's not possible and I've already migrated the 2 HDDs from the HS-251+ to the new NAS, I risk losing the data that's on the UX and for which I don't have any backup.

Following your suggestion, I was looking at the TVS-873, until I just read the announcement of the new TS-x77 series, which supports RAID 50...

[kherr4377]

if the 251 is still operational, it can go right over the network. is the x77 compatible with UX ?? ... no idea. need to ask Qnap

[zylch]

According to this, it should be compatible :

I guess the easiest option is to keep the 251 + UX as a backup system, and just install the TS-1277 as a new system (instead of a migration), with the possibility of expanding it with the REXP.

Cheers!

Why RAID 50 with only 8 slots? RAID 6 will offer much better redundancy while offering the same usable capacity. RAID isn't better with higher numbers, only different.

[zylch]

Maybe I will stick to RAID 6.
If I understand correctly, both the TVS-873 and the TVS-871 need the optional SAS-12G2E adaptor before a REXP-1000 Pro can be attached? Are there any similar desktop models which support the REXP out of the box? I'm not sure if the TS-x77 does.

Not that I know of.

I'm not sure if the TS-x77 does.

It doesn't.

Instead of buying these expansion chassis that are either slow and expensive (UX-line) or extremely expensive (REXP-line) have you considered buying larger and/or multiple NASes instead?

If you insist on using expansion chassis, maybe the TX-line would be interesting? Much better performance than UX, less expensive than REXP and interfaces available out of the box on the TVS-x82T Series and TVS-871T.

how about another QNAP unit and add to the storage pool via VJBOD (and maybe 10GbE ports for speed)

Thanks for all the good advice. I ended up getting a TVS-873-8G with 8 x 10TB, and using my old setup as a backup NAS.
