3D Scaling Scale !"

Increase performance,capacity and connectivitytightly coupled through aglobal cache to meet

increasing server demands.

3D

Solution Capabilities

Host servers can access all the resources that are

dynamically added to the base configuration.

All the resources can act as one system for

maximum performance and capacity.

Managed as one common pool of resources for

more efficient utilization of resources

Dynamically scale for performance, capacity,

connectivity without disruption

Business Value

Industrys highest OLTP performance for open and

mainframe environments.

Grow from a small data center footprint 19 rack

Front to rear airflow for most efficient floor planning

Highest density storage using 2.5 drives

7/24/2019 VSP Tech 01_065966

12/5812


Build out the storage system by combining

multiple units into a single logical system

Dynamically scales out to support the needs

of different servers by prioritizing the

common storage resources

Ensure safe multitenancy and quality of

service through partitioning of cache and port

address space.

Business Value

Tailor for increasing workloads without

compromise Consolidate resources for virtual server

environments

Highest data center density and lowest power

consumption for the capacity stored

Increase aggregate

performance, capacity,throughput, and connectivity

by dynamic allocation of

storage resources to satisfy

multiple distributed host

server requirements.

External storage joins the storage pool with all

the functionality of the storage system

Offloads less demanding data to lower cost

external storage

Simplifies management of external storage with

common management, data protection, and

search

Allows use of existing or legacy assets over

200 storage systems and up to 255PB

Business Value

Increase value and useful life of existing assets Reduce OPEX costs through a common

management framework

Reduce CAPEX using lower cost tiers of

external storage

Storage virtualization can

provide a third dimension ofscaling for consolidating

externally attached storage

systems with virtual servers.

Single Image Global Cache With Dynamic Cache Assignment

Data 'ache S)ste( .lobal 'ache/

Caches user data blocks from drives via theBED during a read

Caches data from the FED as part of a datawrite operation

All write data is mirrored in cache

Only one copy of cached data when performingread operations

Up to 128GB of data cache and a total of512GB in a single control chassis

2 chassis can contain 1TB of cache memory

Non-volatile data protection
