QNAP Turbo NAS Features
QNAP's TS-459 Pro Turbo NAS is the 4-bay, 2.5-inch and 3.5-inch SATA HDD network-attached storage server with iSCSI applications dedicated to SMB, SOHO and home users. As a storage centre for mass data backup, management and sharing, the TS-419P Turbo NAS supports excellent hardware design, outstanding performance, high system reliability, and numerous powerful software applications.
iSCSI for Virtualization Deployments
The Turbo NAS provides flexible and secure storage server deployment with the following enhanced iSCSI features:
* NAS + iSCSI storage solution
The Turbo NAS can serve as a NAS for file sharing and iSCSI storage concurrently.
* Flexible multiple LUNs management
The NAS supports multiple LUNs (Logical Unit Numbers) and iSCSI targets. The LUNs can be flexibly mapped to, unmapped from, and switched among different iSCSI targets.
* Secure IP SAN environment deployment
Designed with CHAP authentication and LUN masking, the advanced ACL (Access Control List) offers you the capability to block unauthorized access from the initiators.
* Designed for virtualized and clustered environments
Comparing with the high cost of Fibre Channel SAN, the Turbo NAS is an affordable system that can be deployed as a storage center for virtualized and clustered server environments, such as VMware and Microsoft Windows Failover Cluster.
Advanced RAID Management with Hot-swap Design
The NAS offers advanced RAID 0, 1, 5, 6, 5 + Spare, Single, and JBOD disk configurations. It also supports hot-swap design that a failed drive can be replaced by hot swapping without turning off the server. Besides, the best-in-class RAID on the NAS brings users a higher level of data security by allowing one more hard drive failure than other NAS of the same level.
Online RAID Capacity Expansion
The storage capacity of a RAID configuration can be expanded by replacing the hard drives with larger ones. All the data will be kept and seamlessly moved to the newly installed hard drives. There is no need to turn off the server during the process.
Online RAID Level Migration
You can upgrade the disk configuration to higher RAID level with the data retained. There is no need to turn off the server during the process.
Virtual Disk Drive (VDD) adds flexibility to storage expansion along with ease of management
The unique "Virtual Disk Drive" adds flexibility to expand the capacity of NAS. By using the built-in iSCSI initiator, the NAS can connect to other iSCSI targets on the network and turn them into virtual disks, which become multiple single volumes on the NAS. Up to 8 virtual disks can be stacked. The NAS serves as the storage stack chaining master. The user only needs to connect to this single entry (QNAP NAS) and is able to reach and use all the iSCSI target storages on the network.
Built-in iSCSI Target Service
The TS-459 Pro can act as a NAS and iSCSI target server at the same time. It provides a cost-efficient iSCSI solution to set up an IP-SAN. You can make use of the built-in iSCSI target service to add up to 8 iSCSI devices. Different iSCSI Target LUNs (Logical Unit Number) can be defined as storage expansion or backup destination of the existing application servers, such as database servers and mail servers.
Furthermore, the "Virtual Space Allocation" (Thin Provisioning) feature is provided which allows you to flexibly allocate the capacity of iSCSI LUN (Logical Unit Number). When the physical storage capacity of the volume is going to be full, you can easily expand the storage capacity by "Online RAID Capacity Expansion", or adjust/ remove the current unused volume space according to the demands.
S.M.A.R.T & Advanced HDD Health Scanning (HHS)
The NAS supports Hard Disk Drive S.M.A.R.T (Self-Monitoring Analysis and Reporting Technology) for monitoring the hard drive status. Moreover, the NAS is embedded with HHS Technology which supports disk checking and bad blocks scanning.
UPS Support
The NAS supports the majority of USB UPS devices (usbhid-ups supported) which enables the users to store the data in time and avoid critical data loss when power outage occurs during data transfer.
QNAP Backup Software - NetBak Replicator
The backup software, NetBak Replicator, is provided for the NAS users to perform real-time synchronization or schedule backup from multiple PCs to the NAS.
3rd Party Backup Software Ready
The NAS works well with other backup software, e.g. Acronis True Image, CA BrightStor ARCserve Backup, EMC Retrospect, Symantec Backup Exec, and LaCie Silverkeeper.
Encrypted Remote Replication
The data on the NAS can be backed up to or from another Turbo NAS over the network securely.
One Touch USB Auto Copy
The one touch button can be configured to trigger instant data backup from the external USB device to the NAS or the other way round (applies to the USB device connected to the front USB port of the NAS only).
Sharing Files across Windows, Mac, Linux, and UNIX
The NAS is designed for users to share the files across Windows, Mac, Linux, and UNIX environment.
Support Windows AD
The Windows AD feature enables server manager to import user accounts from AD domain to NAS to reduce the time and effort for account setup, and users can use the same set of login name and password.
Web File Manager  The NAS provides Web File Manager for you to easily download, upload, and manage the files on the server by web browser.
Ease of User and Share Folder Management
The NAS supports batch creation of users and share folders to save the time and effort of the server manager in account and folder creation. For the security of Windows network environment, server managers can hide or show network share folders.
Hard Disk Standby
You can configure the hard disks to enter standby mode if there is no disk access within the specified period.
Schedule Power on/ off
The flexible schedule power on/off feature is now provided on the NAS for IT administrators to manage the NAS server's up time according to the working hours. You can set the time for automatic system power on, power off, or restart on any days of the week.
Secure data storage, access, and sharing
- Comprehensive event logs: Detailed logs of file-level data access to the NAS via samba, FTP, AFP, HTTP, HTTPS, Telnet, and SSH, and networking services accessed by online users are all recorded.
- SSL security (HTTPS): The NAS can be accessed and configured by web browser securely.
- Remote login to the NAS by SSH (secure shell) or Telnet connection is supported.
- Secure FTP: The data can be transmitted with SSL/TLS (explicit) encryption. Passive FTP port range setup is also supported.
- Write-only access right on FTP server: The third party partners are allowed to upload data to the NAS but not able to read or edit the data on FTP server.
Policy-based Automatic IP Blocking
To prevent the NAS from malicious attacks, the server manager can create an IP filter policy to allow, deny, or auto-block the IP address or network domain which attempts to connect to the NAS via SSH/ Telnet/ HTTP(S)/ FTP/ samba/ AFP.
The most comprehensive support for numerous brands of IP cameras
The Surveillance Station of QNAP NAS supports all the leading network camera brands such as AXIS, D-Link, IPUX, LevelOne, Linksys, Panasonic and Vivotek etc. By using particular models, users can use two-way video and audio monitoring and recording, and smart PTZ control to control the monitoring direction via the web interface. Each of the supported cameras has been put through stringent tests with the NAS series in QNAP's laboratory to guarantee 100% compatibility and reliability with all these camera brands.

gbit + gbit = 2 gbit lan connection

For purposes of evaluation and comparison only the packaged WHS systems like HP or Asus could be compared to the NAS systems. It would be impossiable to quantify the wide variation of surplus "Old PC" configurations and evaluate performance. It would also be interesting to look at a New Build cost for a WHS box using low-cost components.
The HP includes an iTunes server and Twonky media...it can host a website, FTP, print server, and remote access any capable machines on the network (requires XP pro, Vista Pro or Ultimate or Win 7 equilivant).
I am not really debating the merits of either typs but I wonder how it stands up to the speed of these NAS boxes.
* No NIC Teaming
* No 4 Disk RAID5 (to benchmark maximum transfer)
* No NIC teaming on the side connecting to it - like a server connecting to shared storage, at an entry level.
* No testing with multiple clients connected.
Needs more testing guys....
As to bonding making the benchmarks faster... no. 1gbit is good for ~125MB/sec minus overhead of the protocols.
My Win7 machine can copy to/from my wife's Vista machine 110MB/sec. 60-70MB/sec doesn't seem all that fast. I can copy my 3GB Win7 ISO in under 30 seconds.
Both of our machines have only a single HD, not raided, and both are low end Dells. Nothing says low end like an i7 with ATI 4850 and a 360watt PSU
We do teaming all the time on Dell PowerEdge servers and switches, and it certainly makes a difference. While Gigabit maxes out at about 90MB/sec (that's the overhead from 125MB/sec), it would be nice to get more. Especially if you had a couple of systems transferring data to/from the device. I'm not saying I expect these QNAP's to be comparable to an Equallogix PS5000 SAN, but it would be nice if we could get them half-way.
While your single PC to single PC transfer is very good, *I* am more interested in full out sustained MB/sec and/or IOPS to determine if these would be good for say shared storage between two ESX servers in a lab, to test out vMotion, HA, DRS, etc.
This is the other reason why I would have liked to see the tests with all 4 ddrives in use, to get a feel for it's max throughput.
I'd like to point out my 110MB/sec is ACTUAL transfer speeds via windows file sharing and only 4% kernel time to boot.
My plan is to get a server, use my MSDN to drop Windows server on it, plop a few SSDs with a fast RAID controller. I'm thinking I'll have to get a 10gbit card and a nice switch
I also use the Dell Power Edge and if I could access a QNAP, which is 4 or 8 slot tower to rack, 2 rather than 1 Gbit Gbit would be great because it saves lots of money.
I purchased the unit as a cheap file server to host my website at home myself. with some of these cheap cable internet deals from optusnet I think I will have a verrry cost effective hoisting system that should outperform any shared hosting package anywhere out in cyberspace. WIll update things as it progresses.

Yet, as you'd probably have to buy a retail Windows OS box (instead of OEM), it is still an over expensive rip-off.
