+title: Repartitioning the home server
+---
+I have owned Synology 920+ for some two years. Unfortunately, when I first got it, I made some assumptions that are no longer true and therefore this NAS is basically a glorofied Plex machine. A bad one, as the CPU is not powerful for any modern codec transcoding. Time to fix it!
+
+## Durandal
+
+The server (named Durandal) had all drives in Synology Hybrid Raid (SHR) configuration until recenly. When I first bought the device, I got three WD-RED 4 TB drives, which left one bay empty. Soon, the occupied space filled the three drives, and I expanded it with 6 TB - as SHR allows for mixing drive size. In adition, SHR1 allows for one drive failure.
+The configuration looked like:
+
+```
+      HDD1       HDD2       HDD3         HDD4
+    --------   --------   --------   ------------
+   |        | |        | |        | |            |
+   | WD-RED | | WD-RED | | WD-RED | |   WD-RED   |
+   |  4 TB  | |  4 TB  | |  4 TB  | |    6 TB    |
+   |        | |        | |        | |            |
+    --------   --------   --------   ------------
+|                                                   |
+ ---------------------------------------------------
+                   Volume 1 (SHR1)
+                      9.6 TB
+```
+
+This setup has the drawback of not allowing as much storage as required, and storing movie backups on volume with redundancy is an overkill.

+## Vulcan
+
+A few days ago, I rethought the current assumption, and the new ones are:
+
+- I want to host application on the NAS
+- I want to host my photographs (no more iCloud subscription)
+- I want to store multimedia, but I don't care if I lose it.
+
+This led to a new architecture based on two volumes:
+
+
+```
+      HDD1       HDD2           HDD3         HDD4
+    --------   --------       --------   ------------
+   |        | |        |     |        | |            |
+   | WD-RED | | WD-RED |     | WD-RED | |   WD-RED   |
+   |  4 TB  | |  4 TB  |     |  4 TB  | |    6 TB    |
+   |        | |        |     |        | |            |
+    --------   --------       --------   ------------
+
+     CACHE1    CACHE2  
+    --------   -------- 
+   | Samsung| | Samsung|
+   | 256 GB | | 256 GB |
+    --------   -------- 
+|                        | |                           |
+ ------------------------   ---------------------------
+    Volume 1 (SHR1)                Volume 2 (RAID0)
+        3.5 TB                         8.7 TB
+        
+```
+
+Now I have a clear distinction between space for important stuff and for stuff I can recreate with ease. Having 3.5 TB is overkill here, as the drives will sooner fail than I will be able to fill them - currently, I store 520 GB in iCloud... and I pay for 2 TB as there is nothing in between. Having two 2 TB drives there would be much more economical
+
+The total capacity is also significantly higher now. There will be things I'll want to secure that are on Volume 2, but since it won't be anything mission-critical, I can just use a USB Drive for this.
+
+## The future
+
+Since the server is ready, I think I'll strive for:
+
+- adding new offsite backup (or 2) for Volume 1,
+- leaving Plex (temporarily I use Samba shares),
+- adding proper photo storage,
+- adding a music server,
+- adding DNS server,
+- moving this site,
+- moving my XMPP server,
+- adding a VPN server,
+- adding backup power for the NAS, modem, and router.
