I will be building in the next few days my own Network Array Storage (NAS) monster:

  • RAID 6 , instead of RAID5, so 2 disks can fail in the array. A 7 Hot spare is planned
  • Hardware RAID because the cheap motherboard (NVIDIA) only support in best case software RAID5
  • GIGABIT network...
  • Linux powered of course: FreeBSD for security or OpenFiler (RedHat) for it's ease of use...
  • Crypto loop (Linux kernel 2.6 dmcrypt), private keys on USB stick, only 20GB will NOT be encrypted
  • FileSystem: XFS or ReiserFS because I will be storing big files

The hardware will look as follow:

  • 6 Maxtor 7L300R0 MaXLine III, 7200rpm, 16MB, 300GB, IDE, 24/7 server : 60 Months garanty! 104€/each = 624€
  • AMD Athlon 64 3000+  BOX, Socket 939, Venice, the least expensive Athlon 64     99€
  • Asus A8N-VM CSM, mATX, Nvidia 6150/430 Video, socket 939, SATA RAID, because I need PCI-E for the hardware RAID  70€
  • Promise SuperTrak EX8350, SATA2, 8 SATA port, Raid6 Controller, because Promise support Linux   297€
  • Thermaltake Armor (bought previously)
  • Zalman CNPS9500 LED, Socket 754/939/940/478/LGA775  53€

I will explain later why I did not bought a SOHO NAS, but briefly because:

  • For the price of my complete system, I have an empty SOHO NAS box or with 250GB (Raid0)
  • I have 8 + 6 = 14 SATA ports!
  • SOHO NAS are only RAID5 in best case
  • Bad performances of SOHO NAS
More pictures, howto, and benchmarks soon...

ZFS has so much promise that it sound to good to be true! I will make an extensive try of it soon.From ZFS: Threat or Menace? Pt. I.... In a storage industry where the hardware cost to protect data keeps rising, ZFS represents a software solution to the problem of wobbly disks and data corruption. Thus it is a threat to hardened disk array model of very expensive engineering on the outside to protect the soft underbelly of ever-cheaper disks …

I am still testing my NAS system (seven 300Gb disks) and while testing OpenSolaris (under Belenix), and Googling I found that page: This blog is about the Google Summer of Code project "ZFS filesystem for FUSE/Linux" For all of You that do not know what FUSE is, FUSE is the Filesystem in Userspace Linux kernel module. This module allows nonprivileged users to create their own filesystems without writing any kernel code. While ZFS has many features which can benefit all …
