Hitachi Data Systems Competitive Advantage Hitachi Data Systems HUS VM Superior to EMC XtremIO in Versatility, VMware Integration & Data Center Efficiency By Ken Clipperton, DCIG Managing Analyst Hitachi Unified Storage VM delivers a feature rich, enterprise-class, all-flash array with comprehensive data center integration capabilities. COMPANY Hitachi Data Systems Corporate Headquarters 2845 Lafayette Street Santa Clara, CA 96050-2639 408.970.1000 Founded 1989 www.HDS.com INDUSTRY Data Storage SOLUTION • Hitachi Data Systems Hitachi Unified Storage VM DIFFERENTIATORS • Versatility: Unified SAN/NAS, plus Cloud Storage Integration • VMware Integration • Data Center Efficiency Flash memory storage arrays enable a dramatic consolidation of enterprise workloads—and even data centers—by delivering much better performance than traditional storage systems while using just one tenth of the power, cooling and floor space. Annual savings can be many times the cost of the flash storage. Results like these are driving rapid adoption.1 Although these results are appealing, businesses need more than performance from their storage, they also need capacity and a complete set of data services. Hitachi Data Systems delivers the Hitachi Unified Storage (HUS) VM high-performance allflash storage to address a wider range of business requirements than the EMC XtremIO. Versatility Hitachi Unified Storage VM provides both iSCSI and Fibre Channel connectivity plus robust support for file protocols (NFS v2, v3 and v4, CIFS and SMB1.0-2.0) and even object storage capa- Hitachi Unified Storage VM also provides superior monitoring and management of thin-provisioned VMware data stores through support for Thin Provisioning Stun, Out-of-Space Conditions, and Reserve Space APIs. The XtremIO does not support these technologies. Data Center Efficiency The HUS VM stores more data in less space. With a raw flash density of 16 TB per rack unit, the HUS VM stores 4x more raw data per rack unit than XtremIO. While both arrays support deduplication and compression, with the HUS VM these data efficiencies can be applied to 338 TB of flash storage—4x the maximum capacity of the XtremIO. “The Hitachi Data Systems HUS VM delivers on the vision of a single platform for all data.” — Ken Clipperton, DCIG Managing Analyst bilities. In contrast, the EMC XtremIO is a blockonly storage array. The HUS VM’s multi-protocol SAN and NAS capability means it can fit into a broader range of data center infrastructures and provide storage for a broader range of use cases than the XtremIO. For workloads requiring more than 338 TB of capacity, HUS VM can also function as a hybrid storage array and auto-tier data between the flash storage and more than 5PB of hard-drive based storage. Tiering can even be extended to other VMware Integration vendor’s storage systems and the public cloud, all While both HUS VM and XtremIO integrate with under a single management interface.
