RAID10 NAS for GIS geodatabases +ESRI software +LACP
I work for a small non-profit with 11 employees, which is currently being served by a QNAP TS-459 Pro II Turbo NAS, configured with 4-2TB drives in a RAID 5. We acquired this in 2012, and have started to notice some performance issues with larger datasets recently. Most of our staff only works with spreadsheet and document files, however, we do run a small GIS shop utilizing ESRI software and multiple geodatabases and aerial photography data sets. I would like to see what your recommendation would be for a replacement NAS device as well as hard drives to serve our organization. I was looking for something that would support LACP as well as a RAID 10 configuration with 4-4TB drives.
There are several things to keep in mind in this setup. GIS will require very high IOPS- quick input-output operations. This will require minimums few LAN ports or 10GbE, SSD cache and HDD RAID (or SSD) or even tiered storage function. This leads to the Qnap x82 series. The cheapest x82 model is with 4 HDD slots – TVS-682.
If this feel like too expensive, you can consider DS1618+ and fill only 4 bays and maybe use other bay for SSD. It will have 4 ports for load balancing or link aggregation to speed things up.
For absolute budget get DS918+ with nvme caching and dual LAN.
