• Scalable enterprise storage with a dual active/active intelligent array node canisters with 8 GB cache each for high availability and performance.
• Flexible host connectivity to match diverse client needs with support for a mix of 6 Gb SAS, 1 Gb iSCSI, and 10 Gb iSCSI or FCoE or 8 Gb FC connectivity at the same time.
• A 6 Gb SAS drive-side connectivity with support for 12x 3.5-inch LFF or 24x 2.5-inch SFF drives in the control enclosure, which are scalable up to 240 LFF drives per system with the attachment of Storwize V5000 LFF Expansion Enclosure (12x LFF drives each) or up to 480 SFF drives per system with the attachment of Storwize V5000 SFF Expansion Enclosure (24x SFF drives each) to satisfy growing needs for storage capacity and performance.
• With two-way system clustering, the size of the system can be doubled to a maximum of 960 drives.
• Further scalability can be achieved with virtualization of external storage. When Storwize V5000 virtualizes an external disk system, capacity in the external system inherits the functional richness and ease of use of Storwize V5000.
• Flexibility in storing data on high-performance SAS SSDs, performance-optimized enterprise SAS hard disk drives (HDDs), or capacity-optimized enterprise NL SAS HDDs; mixing and matching drive types and form factors within a single system to perfectly meet performance and capacity requirements for various workloads.
• Storwize V5000 combines various IBM technologies, including thin provisioning, automated tiering, external and internal storage virtualization, clustering, replication and multiprotocol support.
• VMware vSphere Virtual Volumes (VVol) integration brings advanced storage management functions to the virtual machine level for finer VM storage service level control and policy-driven automation.
• Intuitive, web-based next-generation GUI for easy system set up and management.
• Extensive interoperability with support for most major server platforms and operating systems.

• Storwize V3700 Controller Unit: 2U rack mount
• Storwize V3700 Expansion Unit: 2U rack mount
• Dual controller (known as node canister) configuration.
• RAID 0, 1, 5, 6, and 10; Distributed RAID 5 and 6 (Distributed RAID is supported with the Spectrum Virtualize Software for V3700 version 7.6 onwards, which requires 4 GB to 8 GB cache upgrades).
• Controller cache 8 GB per system (4 GB per node canister) upgradeable to 16 GB (8 GB per node canister). Battery-backed cache protection.
