The Storwize V3700 supports the complete range of data storage requirements, from highly utilized applications to high-capacity, low usage applications, with the flexible choice of drives.

• High-performance SSDs: 200 GB, 400 GB, 800 GB, and 1.6 TB SAS
• Performance-optimized, enterprise class disk drives:
  • 300 GB and 600 GB 15K rpm SAS
  • 600 GB, 900 GB, 1.2 TB, and 1.8 TB 10K rpm SAS
• High-capacity, archival-class nearline disk drives: 1 TB and 2 TB 7.2K rpm NL SAS

The following 3.5-inch drives are supported:

• Performance-optimized, enterprise class disk drives:
  • 300 GB and 600 GB 15K rpm SAS
  • 900 GB, 1.2 TB, and 1.8 TB 10K rpm SAS
• High-capacity, archival-class nearline disk drives: 2 TB, 3 TB, 4 TB, 6 TB, and 8 TB 7.2K rpm NL SAS

All drives are dual-port and hot-swappable. Drives of the same form factor can be intermixed within the appropriate enclosure, which provides the flexibility to address performance and capacity needs within a single enclosure.

Up to nine Storwize V3700 expansion units are supported by a single Storwize V3700 controller unit. You can intermix 3.5-inch and 2.5-inch expansion units behind a 3.5-inch or 2.5-inch controller unit. This configuration delivers the added flexibility to mix 3.5-inch and 2.5-inch drives within a single system. More drives and expansion units are designed to be dynamically added with virtually no downtime, which helps to quickly and seamlessly respond to ever-growing capacity demands.

The Storwize V3700 storage system is designed to offer high levels of system and data availability with the following technologies:

• Dual-active, intelligent node canisters with mirrored cache
• Dual-port drives with automatic drive failure detection and RAID rebuild with global hot spares
• Redundant hardware, including power supplies and fans
• Hot-swappable and customer replaceable components
• Automated path failover support for the data path between the server and the drives

The following features are included with every Storwize V3700 storage system:

• RAID levels 0, 1, 5, 6, and 10

  Provides the flexibility to choose the level of data protection that is required.

• Distributed RAID 5 and 6
  Helps improve performance and availability with significantly faster rebuild time by allowing data to be distributed across more physical drives that are used simultaneously.
• Virtualization of internal storage

  Enables rapid, flexible provisioning and simple configuration changes.

• Thin Provisioning

  Optimizes efficiency by allocating disk storage space in a flexible manner among multiple users, based on the minimum space required by each user at any time. With thin provisioning, applications use only the space they are actually using, not the total space that is allocated to them.

• One-way Data Migration

  Enables easy and nondisruptive moves of volumes from another storage system onto the Storwize V3700 Storage System by using FC or SAS connectivity.

• FlashCopy

  Enables creation of copies of data for backup, parallel processing, testing, and development, and have the copies available almost immediately. Base software supports up to 64 FlashCopy targets per system.

The Storwize V3700 storage capabilities can be expanded with optional licensed functions. Each optional Storwize V3700 function is licensed on a per-system basis and covers controller unit and all attached expansion units.

To help evaluate the benefits of these new capabilities, licensed functions (with the exception of FlashCopy upgrade) can be enabled at no charge for a 90-day trial period. Trials are started from the Storwize management GUI and do not require any Lenovo intervention. Upon expiration of the trial, the function is automatically disabled unless a license key for that function was installed onto the machine.

The following optional licensed functions are available:

• Turbo Performance

  Turbo performance increases the maximum IOPS and throughput of a Storwize V3700 Storage System. Configurations with greater than 80 disk drives or more than five SSDs are ideal candidates to benefit from the increased IOPS offered with Turbo performance. Configurations with greater than 30 disk drives are suited to benefit from the throughput increase offered with Turbo performance.

• FlashCopy Upgrade

  FlashCopy allows the creation of copies of data for backup, parallel processing, testing, and development, and have the copies available almost immediately. All Storwize V3700 storage systems support up to 64 targets per system at no charge. The FlashCopy upgrade option increases this support to 2,040 FlashCopy targets per system.

• Easy Tier

  Storage tiering helps optimize storage use with data location to improve system performance, reduce costs, and simplify management. Easy Tier automatically and dynamically moves frequently accessed data to flash (solid-state) drives in the system, which results in flash drive performance without manually creating and managing storage tier policies. Easy Tier makes it easy and economical to deploy flash drives in the environment.

• Remote Mirroring

  The remote mirroring feature provides storage system-based data replication by using synchronous or asynchronous data transfers over IP, FC, or FCoE communication links:

  • Metro Mirror maintains a fully synchronized copy at metropolitan distances (up to 300 km).
  • Global Mirror operates asynchronously and helps maintain a copy at much greater distances (up to 8000 km) 

Both functions support VMware Site Recovery Manager for disaster recovery.

For ultimate flexibility, Storwize V3700 remote mirroring interoperates with any other Storwize family system, including Storwize V7000, Storwize V5000, and SAN Volume Controller.

The remote mirroring option must be acquired (or licensed) for the primary (local) and secondary (remote) systems. If Storwize V3700 is mirrored to a system other than Storwize V3700, the other system must have the appropriate and applicable license for remote mirroring.

The Storwize V3700 supports the following management interfaces:

• Web-based graphical user interface (GUI) via HTTPS that requires only a supported browser (Microsoft Internet Explorer, Google Chrome, or Mozilla Firefox), so there is no need for a separate console or plug-in
• Command line interface (CLI) via SSH
• Storage Management Initiative Specification (SMI-S)
• SNMP and email notifications
