Chasing Active Data Set
EMC conducted testing for Oracle RAC environments connected to a dual X-Brick XtremIO Array in an OLTP-style workload with 75% select and 25% SQL updates with a 1TB active data set over an 8 hour period. The graph below shows the consistently fast performance of the XtremIO array when gradually increasing from 192 connections per RAC host to 368 connections during a 60 minute test. The number of IOPS increased 17% and the average services remained relatively flat: ranging from a low of .96ms to a pick of 1.36ms. It’s clear from this test that XtremIO keeps the services times predictably low even when the number of database connections near double!
XtremIO has shown the ability to support a 2X increase in the number of Oracle user sessions and maintain predictable service times, while still driving an increase in IOPS of ~20%.
Today, XtremIO can scale from one X-Brick to two, four or six X-Bricks to provide your database with near linear scalability. In further testing, EMC engineers created an Oracle 11gR2 RAC database on a two-node cluster attached to XtremIO. An Oracle 60 minute performance test was conducted using a single X-Brick configuration and
then repeated across two X-Bricks.
The findings show:

Bring all-flash, scale-out storage to your enterprise applications with EMC XtremIO. Purpose-built for flash, XtremIO storage arrays are amazingly fast. Delivering high IOPS at less than 1 millisecond latency is just the start. EMC XtremIO helps you harness the power of flash storage by building in innovations like content-based data placement and dual-stage metadata.
As a result, you’ll have predictable and balanced performance, always-on data reduction, thin provisioning, data protection, writeable snapshots, encryption, and simple storage provisioning. Ideal for virtual desktop infrastructure (VDI), virtual server infrastructure, databases and analytics, and mixed workload consolidation.
