Protecting Investment and Optimizing Investment Cost

By using storage virtualization to start small and expand as required, this solution provides a storage environment that protects the
customer's initial investment and can flexibly deal with business growth even for systems where future expansions are difficult to estimate.
Storage scalability typically means capacity expansion and throughput improvement.
Capacity expansion is achieved by adding drives. If more expansion is needed, additional drive enclosures can be added to provide space for
more drives. If a large amount of capacity is required for reasons such as business growth, additional storage systems can be installed.
These three ways of adding capacity provide seamless capacity scalability in response to business growth.
In the case of IOPS performance improvement, the IOPS for a specific operation can be upgraded by using flash memory to provide a larger
cache or by selecting high-speed drives (SSDs).
The cache size can be increased up to 800GB for the entry-level ETERNUS DX200 S4 storage system that is used in the example for this
solution or up to 5.6TB for an enterprise storage system.
Furthermore, the addition of a small-capacity SSD can increase IOPS by using AST. This function automatically reallocates frequently accessed
areas to SSDs to provide performance in the way that best suits the operation.
To improve the throughput per unit time, additional ETERNUS AF/DX storage systems can be installed without business downtime. Installing
additional storage systems dramatically enhances the throughput.
In this way, the solution protects the customers' investment by making the most of their initial investment and by allowing additional
investment to be made in small increments.

FUJITSU Storage ETERNUS SF Software for Non-Stop Storage Operation

The FUJITSU Storage ETERNUS SF storage software is used by this solution to provide non-stop operation and to handle the operation and
management life cycle. With an extensive product range that extends from resource management of storage systems to the provision of
additional functions such as replication, it flexibly supports administration of the storage environment and system-wide optimization.
The following sections describe the features of the ETERNUS SF products that provide powerful support for the reliable operation of the
storage systems centered on the ETERNUS AF/DX.

ETERNUS SF Storage Cruiser
system.
Used together with options such as AST
The main functions are as follows.
- Simplified storage design and configuration
A simple GUI is provided for easy configuration, from volume and virtual storage pool creation to allocation to servers.
Users can start small with the minimum physical drive capacity and later add drives without interrupting operation.
- Visualization of storage resources
A dashboard displays information of interest, enabling the status of the storage system and any problems to be identified early.
Performance graphs provide the information for optimizing the I/O performance needed to satisfy business requirements.
It provides integrated management of the components, including the storage system, Fibre Channel switches, physical servers, and
virtual servers using Hyper-V, VMware, or other software.
- Use of AST to optimize investment
AST is used in environments that combine drives of different types to automatically reallocate data to the most appropriate drive based
on access frequency.
It optimizes storage costs by allocating frequently accessed data to SSDs or other ultra-high-speed drives to maintain performance, and
allocating less frequently accessed data to inexpensive Nearline disks with high capacity.
- Use of Auto QoS to allocate performance resources
For systems where the storage system is being shared by a number of operations, Auto QoS prioritizes the I/Os of priority operations
thereby ensuring that high priority operations operate reliably without being affected by fluctuations caused by I/O loads of other
operations.
This makes efficient use of resources by allowing business data with a wide range of different priorities to be combined.
Response times can also be reduced by using automatic tuning together with AST.
The ETERNUS AF/DX and ETERNUS SF Storage Cruiser together provide an ideal system for maintaining business continuity that can be
used safely and reliably.
