Evaluator Group Comments:

The NAS from IBM cover the traditional areas that NAS has been applied - the departmental and workgroup environments. These products are priced incredible low and should allow IBM salesmen and their business partners to be very competitive in the market. Choosing the specialized Windows OS is also a very wise move as the operating system has been fine-tuned to operate as an appliance and has the support for "hard locks" that is becoming a significant security advantage. These products will replace the previous Xseries 150 product. The Evaluator Group believes that these products, including the clustering feature for the 300G, will make IBM a formidable competitor in the traditional NAS markets.
