Thecus iSCSI Storage i5500 Move Array to thecus NAS N7700 Storage

Hi,

I have an i5500 with 5 x 3TB drives running 2 volumes of 1 x 7451 GB Raid 0+1 called Data LUN 0 and 1 x 3725 JBOD called temp LUN 1 with the SES global cache.
I have an empty N7700.
I have been running Win 7 x64 to the i5500.
A Nero backitup cloud backup is syncing files with the Data volume.

I now have a number of laptops that need to connect to Data. I understand the i5500 is dedicated to one PC over iSCSI.

Can I pull the 4 drives from the i5500 and put them in the N7700?

If so what do I need to follow / do?

regards

I'm not familiar with the i5500 but I've used the N5200Pro (still do, in fact) and the N7700Pro. If I recall correctly the Thecus kit is just using mdraid under the hood, and as such you should be able to move the disks (try to keep them in the same order) to the new unit and the RAID should Just Work.


That said: you can't do what you're trying to do. You'd need to move the data off the Data volume to a volume that is available as a share: when you create a volume on the N7700 you allocate an amount as "data" (ie CIFS) and an amount for iSCSI storage - once this is set it's set and Windows isn't generally a cluster aware OS. The iSCSI storage is block storage, and you need file storage so you'll need to create a new volume on the N7700 (so you may need to buy more disks) and assign that as a data volume, then share it out.

TBH, I would try and back all the data up and start from scratch, maybe with an additional disk.

Scratching my head as to how those arrays are setup, in fact a 7.5TB Raid 0+1 cannot be made with 4 x 3TB drives..that would max out at 6TB.

Thanks I am going to copy the i5500 to the N7700.

I have read HowtoUseRAIDVolumeReplication.pdf I have a Thecus i5500 with RAID10 and 4x4TB hard drive and a 4TB master. I want to back up the data of about 3TB to a cloud backup called Nero backitup. I have been doing it but its too slow on the Internet ADSL2+ 0.75GB/s link.

I have 2 unused NAS both empty N5500 and N7700 both firmware 5.03.02. I have a location I visit weekly with Internet FTN 36MB/s. I have lots of 4TB seagate drives blank.

Can I transfer use RAID Volume Replication between the units to somehow to offsite backup the data on the i5500 and then backup the data to the cloud at the remote location.

I am also decommissioning the i5500 PC running iSCSI. Therefore the i5500 does not need to be retained in its current use.

I was thinking that I transfer the data from i5500 to N7700. Break the N7700 mirror and use RAID volume replication. Then take the RAID 0 replication to the N5500 on the FTN fast internet and cloud back up this on a weekly basis. I would like the N7700 to run a raid 10 on the source replicating volume and raid 0 on the target volume.

The Nero backitup is an unsophisticated file backup system that will detect the changed files and back them up. The best outcome if the PC running the N5500 share does not detect the N5500 has changed. If the RAID replication is a true 1:1 then the swapped replication volume will be transparent to the Nero backitup and it will continue its file checking and change backup on each swap. The record of the backup is kept PC side and cloud side not on the NAS.

I hope you can help.
