WMS100

As an entry point to our new midrange systems line, the serial ATA (SATA)-based Hitachi Workgroup Modular Storage model 100 (WMS100) offers high capacity, easy-to-install data storage ideal for small and medium businesses (SMBs). The WMS100 provides the foundation for Services Oriented Storage Solutions, matching requirements for the cost-effective scalability and performance in a small footprint while maintaining the reliability edge provided by renowned Hitachi engineering. Example: Businesses deploying their first storage area network (SAN) are able to move from inefficient and costly server-internal or server-attached storage to a centralized, easy-to-manage configuration. Or those with fast-growing Microsoft Exchange or database applications can quickly catch up and keep pace.

For larger companies, the WMS100 complements the Hitachi Adaptable Modular Storage (AMS), Universal Storage Platform V (USP V), and Universal Storage Platform VM (USP VM) in tiered storage deployments that require common management tools, nearline backup and data movement for data lifecycle management (DLM) applications.
