I've start looking at RAID 5 NAS array (a way to ensure redundancy of data and allow a set of files to be accessible across a network of machine) system 2 months ago, reading a lot of articles at the best hardware reviewers:
Anandtech which has made review of the major NAS on the market: Buffalo, Infrant (X6 and NV)
A lot of new products have appeared in the last months, sign of a consumer demand. I have a lot of possibilities, each with their strengths and weakness:
Infrant Ready NAS NV
Build my own small system, ($300 without disks), an ASUS Nforce mainboard (Gigabit, PCI-E, Video), an Athlon X64 3200MHz, but the CPU alone consume 90Watts (less in economic mode) and it is difficult to find a power supply under 200Watts. I already have a box (A mini ThermalTake tower for sure too big in the living room)
Buy a InfrantReadyNAS NV ($900 without disks), because it has a great community (Forums), is small, look nice, consume only 50Watts. But I am concerned by performances problems (not consistent, good in read). Attention it is by far the faster SOHO NAS on the market as it outperform Buffalo Terrastation, Synologic base NAS by figures. [AnandTech]
Buy a Intel SS4000E ($850 without disks), mainly because its small, run dedicated XOR engine at 400MHz vs only 200MHz for Infrant NV, but it also consume a lot more: 200Watts, and it hasn't been reviewed till now. Intel technical sheet also state that the CPU can reach 600MHz.
Buy a dedicated RAID 5 hardware card, there is a lot available, but their prices are ridiculous for a personal use, more than 400 euro and for a little more it is today possible to build a top system based on a NFORCE4, Athlon XP64, Memory. Linux driver support is not bad (Promise, Escalade) but their drivers are not open source. This option fell down, as I do not have a PCI-Express port on my A7N8X NFORCE2, and may want to get rid of that big tower soon.
I also want to have a LINUX powered NAS, because I feel more confident with Linux file system, where filename case is relevant, kernel can get stripped down to what it really need, and do not require a costly license (Windows XP or Embeded 2003 are out). I found a lot of open source and free RAID operating system: OpenFiler, FreeNAS, NasLite for naming a few.
Wait for the Intel SS4000E review, or hope for a faster ReadyNas from Infrant.
Keep my biggest tower (huge Thermaltake Armor) and run on a new mainboard (Time to get rid of my 2001 mainboard NFORCE2? ) a software RAID array.
I expect to build a Linux NAS Raid 5 array made of 4 Maxtor 7L300S0 MaxLine III, 7200rpm, 16MB, 300GB, SATA, 24/7, 1M MTBF(5 years garanty) as I already have 2 of them and found them reliable, for a total of 3/4 * 1200GB = 900GB of raw data, and hook to it 2 external USB disks (OneTouch 250GB and OneTouch2 250GB).
The Seagate® Momentus® XT drive enables laptop PC users to enjoy solid state-like performance without sacrificing storage capacity and affordability. The Momentus XT solid state hybrid drive utilizes Adaptive Memory™ technology to dynamically optimize performance by aligning to user needs. This perfect balance of SSD and HDD delivers low heat, noise and vibration, and is available in capacities up to 500GB. Here is the drive I am testing, information you can easily found with drivedetect.exe (http://support.seagate.com/kbimg/utils/drivedetect.exe) Model: ST95005620AS, Serial: 5YX03VW9, …
I've made many errors when building my NAS server, and this force me to forget using SUN Zeta File System, at least for this year...In fact I have decide to build a NAS before even knowing the existence of ZFS, and bought following hardware components: 1 Promise Supertrak EX8350 with 8 SATA2 3GB port (RAID6)The cheapest integrated mainboard available: NFORCE4 IGPAMD64 3000+ …
Before putting my monster NAS online (pictures will follow soon), I am playing a lot with NEXENTA under VMWARE player.I've found that excellent PDF (THE LAST WORD IN FILE SYSTEMS) which explain why ZFS may be the Saint Graal of file system, while if you want to learn how to administrate pool, I recommend YouThe ZFS admin guideHere is my first try, with 7 simulated disks (this example use files and not real devices even if I have 7 real …
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 …
origin: WikiPediaSAMBAAn open source implementation of the SMB file sharing protocol that provides file and print services to SMB/CIFS clients. Samba allows a non-Windows server to communicate with the same networking protocol as the Windows products. Samba was originally developed for Unix but can now run on Linux, FreeBSD and other Unix variants. It is freely available under the GNU General Public License. The name Samba is a variant of SMB, the protocol from which it stems. As of version …
Putting OpenSolaris in a NAS server OpenSolaris is an open source project created by Sun Microsystems to build a developer community around the Solaris Operating System technology OpenSolaris express is the official distribution and can be download HERE but I will use a fork of that code. …
