Ameren Selects Two EMC VMAXs

EMC Corporation announced that Ameren
Corp., a power company with 3.4 million electric and gas customers in Missouri
and Illinois, selected Symmetrix VMAX to manage its  data growth in an
Oracle database and custom application environment.

This
supports Ameren’s new initiatives, while accelerating its adoption of a private
cloud infrastructure with VMware vSphere virtualization and cloud
infrastructure technologies.

EMC was recently named by customers as the #1 storage choice for
Oracle and other mission critical environments according to a survey by IDC.
The survey ranks the storage vendors based on how end-users are deploying their
technology with enterprise applications. In addition, EMC was also ranked as
the top vendor for Microsoft Exchange and SharePoint, SAP, Business
Intelligence, Analytics, Virtual Desktop Infrastructure and Home Directories.

Customer Benefits:

• Increased Savings: Reduced annual capital expenses by 50% using EMC’s
  Fully Automated Storage Tiering (FAST).
• Improved Performance: Increased transactional performance by 30% and
  batch processing performance by nearly 20% using EMC VMAX.
• Reduced Footprint: Consolidating on VMAX enabled Ameren to
  achieve power and cooling savings of 28%.
• Increased Scalability: Ameren can now scale its data center to handle
  unpredictable growth from smart grid and business analytics.

Customer Challenges and Solution:

With 100 terabytes of data being added to its infrastructure each
year, Ameren was struggling to keep up with its data growth and increasing IT
management costs while advancing its VMware virtualization and cloud computing
strategy. Recognizing that emerging smart grid applications would increase data
volumes even further, the company needed a way to reduce costs without limiting
its ability to grow. After assessing its requirements and considering solutions
from EMC, IBM, Hitachi and NetApp, Ameren selected EMC VMAX for its
performance, intelligent management, scalability and cost-efficiency.

To meet its need for increased scalability and performance, Ameren
deployed a VMAX storage system with enterprise Flash, FC and SATA
drives, while also taking advantage of EMC FAST to reduce costs.

To maximize uptime, Ameren utilizes EMC SRDF/A software, which
replicates data between the VMAX system in the company’s production data center
and a second VMAX in its disaster recovery and development data center 100
miles away. Ameren manages its VMAX environment using EMC ControlCenter,
Symmetrix Manager and Symmetrix Optimizer to simplify system configuration,
monitor and control SRDF replicas, and optimize performance.

John Hughes, Director of Hardware Infrastructure, Ameren Corp. said: "We had a sprawling shared-disk environment that didn’t scale
cost-effectively and used a lot of power. We chose EMC VMAX because it could
drastically reduce our data center footprint, lower our power demand and fit
our cost model.

"With VMAX and FAST, we were able to move a number of our key
applications onto lower-cost disk and maintain good performance. It’s a
no-brainer – by tiering, we’ve lowered our annual working capital 50%.

"As an energy company, we’re very focused on conservation. With
VMAX and VMware, we’ve lowered our energy demands by 28%, resulting in much
greener data centers. We also can allocate capacity much more quickly and
dynamically to better manage growth. Even though we can’t predict our exact
future requirements, VMAX provides us with the elasticity and growth
capabilities to support whatever smart grid and business analytics initiatives
come down the road.

"Our benchmarking showed that we improved transactional
performance by 30%, which directly affects our responsiveness to customer
calls. We also increased batch processing performance by 20%, enabling us to
now complete our billing cycles in as little as four hours compared to up to 8
hours with our previous storage solution.

"VMAX is helping us to become 85% virtualized in the near
future. VMAX is one of our key building blocks to embracing cloud.

"With VMAX’s excellent reliability and intelligent management
tools, we’re spending less time on troubleshooting. In fact, our after-hours
service calls dropped by half."
