IOCELL NetDISK 351UNE Features
The NETDISK Solo is a user-friendly, direct network interface storage unit, with proprietary NDAS technology (Network Direct Attached Storage). The primary advantage of this technology is that it allows direct connection to a TCP/IP-based network without the need for IP configuration. If you look at the trade-offs between storage architectures and complexity, the Storage Area Network (SAN) is at the top, Network Attached Storage is in the middle, and NDAS is at the bottom. In many cases, the bottom is a good place to be, especially when it comes to cost and complexity. Let's take a brief look at the feature set you do get, with this low-cost, lightweight technology.The Feature-rich and Integrated Applications for Business
Virtual RAID Management with RAID 1 +Spare
The NetDISK NDAS offers the ability to create RAID 0 and RAID 1 volumes from individual units attached to the network. It's kind of a peer-to-peer architecture, that is actually a bit more fault tolerant than having all your drives controlled from one controller, and powered from one PSU. It also supports hot-swap for failed drives, and a "Spare" drive can be added to a RAID 1 volume for increased flexibility.
NDAS Technology Reduces Complexity
When you compare the architecture of a typical NAS server implementation to one using NDAS technology, you can readily see the reduction in complexity. I think this chart really needs one more box on the NDAS side; that's the Lean Packet Exchange (LPX) protocol, and it would go where the green TCP/IP box is on the right hand side. After all, you have to have LPX installed on the "host" PC. It's a simpler, faster protocol than TCP/IP, but you can't pretend it's not there....
NDAS Technology Provides Granular Access Rights
During setup and driver installation for each PC on the network, there is an opportunity to set write privileges for each node. You cannot set separate privileges for different user accounts on each PC, the rights are assigned to all users. Also, even if someone tries to install the driver package on one of the other PCs on the network, without the unique NetDISK ID and Write Key, they will not be able to access the NDAS storage device.
NDAS Technology Safeguards Your Storage From TCP/IP Hacking
There is an additional advantage of the Lean Packet Exchange (LPX) protocol, which is used to interface the NetDISK unit to the Router or Switch that's used as a gateway into the network. LPX is a tiny player in the network world, and very few hackers are going to even know it exists, and even fewer are going to bother spending their time trying to break into it. So far, I haven't heard any claims that it's "hardened" in any way, just that the million or so methods that are commonly used to hack TCP/IP don't work on LPX. It's not airtight security, but it does keep you safe from 99.999+% of the attacks that might come your way.
Those are the basic features of the IOCELL NetDISK 351UNE. In the next section we'll dive into the included software to show you how all these features are implemented.
