DIY SAN/NAS – quest for fast, reliable, shared storage with a twist of ZFS! (Part 1)
Choosing prebuilt SAN is cheating – let’s build something from nothing and learn ZFS on the way! Read more about my FreeNAS/ZFS adventure using a Dell R510.
How does disk performance really affect VMs?
Part 1 Most people know that SSDs are fast with high IOPS and mechanical disks are slower, offering less speed per unit and lower IOPS, but a better cost per TB. Most “high end” enthusiast SSDs (read: consumer) these days will offer 400+ MB/s and at least 70k IOPS at medium queue depths. Mechanical disks might only offer 75 – 140 IOPS per disk and 100 – 125 MB/s transfer. However, we also know that we can...
Lenovo TS140 as ESXi and NAS box – with a twist!
This is “Part I” – as a sort of “Part II” I’ve upgraded this server some – click this link to read more about that, otherwise continue on!

The Lenovo TS140 was on sale at NewEgg on their eBay store and included the Intel Xeon E3-1225v3 (3.2GHz quad-core) with 4GB of RAM,...
Synology DSM 5.0 ShellShock “safe by default”
So I was on twitter looking at some security stuff I follow and came across someone quoting Synology as saying that DSM 5.0 is “safe by default”. Here is a link to the Synology document. And here is the quote: The design of Synology NAS operating system, DiskStation Manager (DSM), is safe by default. The bash command shell built-in in DSM is reserved for system service use (HA Manager) only and not available to public...
Synology DSM 5.0 Update 7 fix for ShellShock vulnerability
Synology released their fix to the recent ShellShock bash vulnerability with release 5.0-4493 Update 7. So, you should consider updating your device when possible. Interestingly enough, a DS214+ does not have the release available (yet?) but a DS1513+ does: So, that’s peculiar – maybe DS214+ does not support bash shell? Hm.
