• 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.

• Scalable, modular storage with dual-active intelligent array node canisters with up to 8 GB cache per canister.
• Flexible host connectivity to match diverse client needs with support for 6 Gb SAS and 1 Gb iSCSI connectivity standard, with optional 10 Gb iSCSI or FCoE, 8 Gb FC, or extra 6 Gb SAS or 1 Gb iSCSI connectivity.
• 6 Gb SAS drive-side connectivity with support for 12x 3.5-inch large form factor (LFF) or 24x 2.5-inch small form factor (SFF) drives in the controller unit; scalable up to 120 LFF drives per system with the attachment of LFF expansion units (12x LFF drives each) or up to 240 SFF drives per system with the attachment of SFF expansion unit (24x SFF drives each) to satisfy growing needs for storage capacity and performance.
• Flexibility in storing data on high-performance SAS SSDs, performance-optimized enterprise SAS 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.
• Rich set of standard functions are available at no extra cost, including virtualized internal storage, snapshots, thin provisioning, data migration, and data replication.
• Optional licensed functions, including higher number of snapshots for added scalability, Turbo performance, Easy Tier, and remote mirroring.
• 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 GUI for easy system set up and management.
• Extensive interoperability with support for most major server platforms and operating systems.
• Conforms to applicable Network Equipment Building System (NEBS) level 3 documents and to applicable European Telecommunications Standards Institute (ETSI) documents
