NAS for iSCSI/media/files

1.8TB SATA3 in RAID-1 configuration.

I have now switched my ReadyNAS Duo v2 with a ReadyNAS Ultra 2 Plus, which is the business-edition of Netgear's 2-bay NAS boxes. Way better equipped for my needs.

Hardware:

  • Intel Atom dual-core 1.5GHz (x86 instead of arm5 as in Duo v2)
  • Dual Gigabit RJ-45 LAN ports
  • 2 x USB 3.0 on back-panel (one over each gigabit LAN port)
  • 1 x USB 3.0 on front-cover (for "backup"-button)
Accessories:
  • 2 x Western Digital Caviar "Green" 2TB SATA3 hard-drives

The Ultra 2 Plus business-ready revision of the dual-bay NAS from Netgear offers more advanced configuration and customization options, and also complies with Linux networking protocols (NFS, SSH, SFTP, etc.), unlike the Duo v2 which only offers AFP and SMB file-sharing (Apple and Windows network file-sharing respectively) and basic configuration.

What really makes it stand out is its ability to share iSCSI targets. Basically, it can share portions of its RAID-array as virtual hard-drives for Virtual Machines run either by for example VMware or VirtualBox on a server, or via a bare-metal hypervisor (ex.VMware ESXi, my personal favorite ;).

Extra functions in the Ultra 2 Plus compared to Duo v2, are for example the possibility for scheduled RAID-scrubbing and/or volume checking, to keep your RAID volumes clean and fixed :)
