Software
Note: Storwize V3700 functional capabilities that are described in this product guide are based on the
Spectrum Virtualize Family Software for Storwize V3700 version 7.8. The Spectrum Virtualize Software for
Storwize V3700 version 7.8 requires 8 GB cache memory per node canister.
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 HDDs 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.
