The majority of NAS storage systems offered today work on a specially optimized for file services version of Linux / Unix. This feature of the NAS turns into a serious disadvantage if this storage system is installed on a local network consisting only of Windows computers. Often, special settings are required in order for the NAS to properly interact with the Active Directory directory service. In addition, often system administrators serving Windows networks have never worked with Linux / Unix environment before, so in order to fully utilize such NAS, they need to master a new operating system.

November 29, HP introduced the second generation of its NAS-based X5000 G2 Network Storage System, running Windows Storage Server 2008 R2 Enterpise Edition. The X5000 G2 comes with an already pre-installed OS and it takes less than an hour to deploy this NAS on the Windows network, including integration with the Active Directory directory (this was confirmed by testing in the independent
Tolly laboratory ).
If the first generation of X5000 systems consisted of a three-unit server module and a three-unit disk array, then the X5000 G2 used a construct from two HP BladeSystem c-Class two-height half-height blades and a disk module with 16 SAS hard drives installed in one three-unit shelf (the same The constructive is also used for the
HP E5000 Messaging System for Microsoft Exchange Server 2010 e-mail solution released this spring. The base system is scalable up to 32 TB and in the configuration with SAS 15K rpm disks easily provides file services for ten thousand users, i.e. It completely covers the storage needs of a medium-sized company and may be suitable for consolidating file servers in many large corporations. Further, the system can be expanded by adding disk shelves of the D2000 family with large LFF or small SFF disks, increasing the total capacity to 128 TB.
To protect against equipment failures, the X5000 G2 blades are integrated into a fault-tolerant active-active cluster, and in addition, all the main components of the system are reserved. For ease of deployment in branch offices, it supports caching of frequently requested Windows Server Branch Cache files and proprietary iLO remote management technology (familiar to HP ProLiant server owners), and deduplication is used to get rid of storing the same files. To save space on the X5000 G2 disk resources, the system administrator can enter quotas for individual users and groups and apply rules to block writing files to discs using the classification function. Finally, the built-in snapshot and replication features help to create copies of files in case they are accidentally deleted or modified.

The X5000 G2 already includes a license for the iSCSI target and is therefore able to work with data not only at the file level, but also at the block level when servicing databases, application servers and virtual machines. All the functions mentioned are part of the standard X5000 G2 configuration, so the owners of this NAS do not need to spend extra money on licenses for additional software.
