About this site
This web site ( marzke.net ) and many others run on free (open-source) software. For details on the tools used see below:
- Dell PowerEdge 2950 2U server.
The host is a 2U dell server with 6 internal 2TB drives.
- VMWare vSphere 5.5
This site's server runs VMware vSphere 5.5 (ESXi 5.5) on the above hardware.
Primary VMware storage is currently based on SmartOS Cloud operating system using the built-in ZFS based storage sub-system. ZFS in the Global zone is used for storage, with NFS enabled on each ESXi share. SmartOS is based on Illumos ( a fork of now defunct OpenSolaris ). SmartOS runs on a Dell 2970 III server with 2 CPU, 32GB RAM , 6x 2T SAS drives , and 2 x Intel 320 SSD drives. The Intel drives are Single-Level-Cell (SLC) technology to maximize write cycle durability and also have built-in super caps to insure writes complete during a power failure event. SmartOS runs from an internal USB flash drive, so all 6 SAS drives are fully available to the Zpool storage.
- Nexenta SDS"
Primary storage was previously provided by Nexenta Software Defined Storage appliance running as a VM on ESXi. Because of the large amount of RAM required for caching, the storage appliance was moved to a separate physical server and ZFS migrated to the open source SmartOS system which doesn't have licensing restrictions.
- Thecus SAN
Secondary / backup storage is provided by an 12TB Thecus rack-mount supporting both iSCSI and NFS
