An external hard drive that thinks it’s a NAS

The NetDisk 351UNE that IOCell Networks announced Wednesday is an external hard drive enclosure that can house a SATA hard drive of any capacity. Apart from the USB 2.0 and eSATA connections, what makes the NetDisk 351UNE different from all other enclosures is that it also has a Gigabit Ethernet port.

This means that apart from hooking up to a computer as a direct-attached-storage device, the NetDisk 315UNE can also be connected to a router, just like a NAS server. However, unlike an NAS server that can work by itself to access the NetDisk over a network, you will need to install its NDAS software on one of the networked computers. The computer then becomes the host let lets others computers access the data stored on the device.

So, basically, this is a network-direct-attached-storage device which, like all external hard drives, depends upon a computer to work.

The Btrfs file system (ZFS vs btrfs)

H-online has an interesting post explaining Btrfs, the designated “next generation file system” for Linux:

Btrfs, the designated “next generation file system” for Linux, offers a range of features that are not available in other Linux file systems – and it’s nearly ready for production use.

If the numerous articles published about this topic in the past few months are to be believed, Btrfs is the file system of the future for Linux and the file system developers agree: Btrfs is to be the “next generation file system” for Linux. The general consensus is that Btrfs is the ZFS for Linux. While this may be disputable at present since the ZFS, designed by Sun Microsystems for the Solaris Operating System, is already in production use, while Btrfs is still highly experimental, the two file systems do have a lot in common. With its integrated volume management, checksums for data integrity, Copy on Write and snapshots, Btrfs offers a range of features unrivalled by any of the Linux file systems currently in production use.

Btrfs, which is called “ButterFS” by some people and “BetterFS” by others, is actually short for B-Tree File System, and is so named because the file system manages its data and metadata in tree structures. Masterminded by Oracle developer Chris Mason, the file system has been a part of the Linux kernel since Linux 2.6.29. However, this doesn’t mean that it is stable, let alone suitable for production use. The Btrfs page at kernel.org clearly points out that not even the file system’s on disk data formats have so far been finalised.

SAN-RAID devices offer storage options for IP video systems

Designed for use in Storage Area Network, iSCSI SAN-RAID models do not need to be connected to and in

close proximity to DVR or NVR. Instead, units exist as part of network and can store video from one or multiple network recording devices regardless of physical location. Devices utilize iSCSI protocol, which allows them to transmit and receive signals over regular Ethernet cabling. Available with 8, 14, or 42 bays, SAN-RAID models provide storage from 3.3-36 TB.

Vicon Industries Inc., a leading designer and producer of integrated IP video surveillance and access control systems, is replacing its line of RAID storage devices with new iSCSI SAN-RAID models that make use of newer networking and storage technology. Like traditional RAID devices, the new models feature multiple, hot-swappable hard drives that provide highly secure storage of large quantities of recorded digital video. However, the new models are designed for use in a “Storage Area Network,” meaning that they no longer need to be directly, physically connected to and in close proximity to a DVR or NVR. Instead the SAN-RAID units exist as part of a network and can store video from one or multiple network recording devices regardless of their physical location. Compared to the traditional “one-RAID-per-NVR” model, the SAN-RAID option therefore offers savings both in cost and physical space required by the units.

In addition, the new SAN-RAID devices make use of iSCSI protocol, allowing them to transmit and receive signals over regular Ethernet cabling (CAT-5 and other options). iSCSI protocol can transmit signals up to 25x farther than traditional SCSI connections used by the previous generation of RAIDs.

Vicon’s new SAN-RAID devices are available with 8, 14 or 42 bays and provide varying amounts of usable storage, ranging from 3.3 to 36 TB. They will be available for shipment beginning mid July.

“Vicon’s commitment to IP-based, open platform video management is clearly evidenced by the range of products we continue to bring to market, from megapixel cameras to NVRs to these state-of-the-art SAN-RAID storage solutions,” stated Margie Gurwin, Vicon’s Director of Marketing. “We are pleased to offer our customers the best that technology has to offer.”

Cisco 4 Bay Advanced Gigabit Network Storage System Chassis

Cisco 4 Bay Advanced Gigabit Network Storage System Chassis information:

The intelligent Cisco NSS6000 4-Bay Advanced Gigabit Storage System Chassis gives administrators and integrators the flexibility to optimize the network storage system (NSS) for performance, capacity, and the company’s storage and sharing needs. The NSS6000 supports up to 132 concurrent, connected Common Internet File Systems (CIFS) (Windows, Macintosh, Linux) users.

The Cisco Small Business Network Storage Systems bring robust network attached storage (NAS) within reach of today’s budget-minded workgroups and small businesses. They are ideal for storing, backing up, sharing and archiving critical information. The feature set of these network storage systems sets them apart from entry-level, desktop NAS systems, while at the same time their competitive pricing gives small businesses the opportunity to realize substantial cost savings when compared with more expensive storage systems.

Unlike other NAS systems, which need to contain operating system software on one or more hard drives, the Cisco Small Business Network Storage Systems feature a unique and intelligent chassis containing the Linux operating system that controls it. This gives the storage system added stability and reliability, as well as the flexibility to be configured without connected drives or reconfigured at any time – even hot swapping and re-sorting hard drives to different storage bays. This flexible architecture makes the Cisco Small Business Network Storage Systems ideally suited for budget-conscious companies that are constantly growing and evolving.
