No storage solution is ready without Apple’s filing protocol implemented (AFP). Volker has finished the plugin.

The Apple Filing Protocol (AFP) is a network protocol that offers file services for Mac OS X and original Mac OS. In Mac OS X, AFP is one of several file services supported including Server Message Block (SMB), Network File System (NFS), File Transfer Protocol (FTP), and WebDAV. AFP currently supports Unicode file names, POSIX and access control list permissions, resource forks, named extended attributes, and advanced file locking. In Mac OS 9 and earlier, AFP was the primary protocol for file services.

Ars Technica has an interesting article on the background of SANs, how they work and how Isilion SAN systems work.

Big data meets big storage: an in-depth look at Isilon’s scale-out storage solution

We’ve gone far afield of the original subject here, so let’s swing back to it. As I said a few paragraphs back, Isilon makes a scale-out NAS product that you’d use to hold files. What makes Isilon different from other NAS systems, though, is that it’s particularly suited for providing very fast access to very large files, which makes it a shoe-in for the entertainment industry and for other areas where you need to manipulate big file-based data sets.

An Isilon system consists of a minimum of three Isilon nodes, each of which are individual servers running “OneFS,” a heavily modified FreeBSD derivative, and connected to each other through a fast private IP network. Instead of Ethernet, this private network uses Infiniband for its transport, which Isilon chose because of the extremely low latency it offers versus traditional Ethernet. Unlike a regular SAN or NAS, the nodes all work together in a grid to present a single volume, equal in size to the aggregate capacity of all the nodes’ disks. As nodes are added to the system, their capacities are seamlessly added to the one big volume, without the need to futz around with RAID groups or LUNs or mapping or masking or storage pools or anything else, really. This one single huge volume is Isilon’s core feature—even with all the features and tools that an enterprise NAS system gives you, there aren’t many NAS systems that can present a single, unified multi-petabyte namespace.

Network-attached storage (NAS) devices are a popular in small- to medium-sized businesses (SMBs). NAS storage systems help to simplify expanding networks, and many NAS products are now offering enterprise-like features for SMB environments.

According to Greg Schulz, founder and senior analyst at the StorageIO Group, there are a few NAS trends emerging for SMBs.

“One hot SMB trend is the continued deployment of NAS as both a primary storage device as well as a backup target or staging area before data gets moved elsewhere including to cloud or MSP services. The versatility of NAS is enabling SMB environments to do more with their storage, maximizing those resources and budgets.”
