Today, digital technologies are revolutionizing power markets, making them smarter, more dependable, and more environmentally friendly. This inspired a Fortune 500 energy company to embrace new solutions that offer more control and choice to its more than 6 million retail customers across 24 states. The same tech-forward mindset also led the energy giant to achieve greater sustainability and resource management through new smart home solutions, digital consumer web and applications, solar energy production, and other strategic technology imperatives.
Recently, this energy giant was confronted with a new challenge: exiting a leased data center in North Carolina and transitioning 2.5 PB of crucial business applications and data to a facility it owned in Texas. This relocation needed to be completed within a strict 9-month deadline to avoid contract penalties. With its additional technology initiatives and focus on sustainability, the company decided to upgrade to a new Pure Storage system that promised to both enhance the company’s storage performance and deliver cost benefits.
But the clock was ticking. Because energy delivery and consumption is an around-the-clock business, there is never a good time to take applications and databases offline. Further complicating the process, the energy company’s telecommunications provider charged a high price for its fastest data connections. This meant the energy company could not perform the full migration remotely without excessive costs and delays.
After successful collaborations with Cirrus Data Solutions (CDS) in the past, the energy company turned to CDS for this time-sensitive data center consolidation. To circumvent the telecommunication hurdles reduce costs and get the project completed on time, the Cirrus Data professional services team devised a ‘lift and shift’ strategy. This meant shipping the new Pure Storage system and CDS Remote Migration Appliances to North Carolina
and using Cirrus Migrate On-Premises to migrate the data over multiple high speed locally attached network connections in the source data center. This allowed the customer to not have to transfer the entire 2.5PB plus all the real time changing data over a small, contentious remote network link. There was no business disruption or downtime during this migration. Cirrus Data was able to use its intelligent QoS (iQoS) to migrate live data to the new system without impacting the applications’ performance. The new fully loaded storage system and CDS Remote Migration Appliances were then securely transported to the Texas data center and installed.
Before the new system was turned on, Cirrus Data also used Cirrus Migrate Cloud for the boot drives and Cirrus Migrate On-Premises Remote to migrate and keep updated the internal server’s locally attached boot drives at the remote location, moving vital OS, application and configuration information allowing for the remote data center servers to be immediately booted upon cutover of the applications and databases to the new data center.
During this boot drive migration, the CMO Appliances then kept the real time changing data deltas and the remote site kept in hourly synchronization with the new Texas Data Center.. Because only a limited delta of data needed to be transferred remotely, the energy giant could use an affordable 10GB connection. This approach securely migrated 2.5PB within the required timeframe and enabled a swift cutover with near-zero downtime.
The Cirrus Data professional services team managed the entire project. When the energy company realized they had forgotten to include its boot drives in the project, the Cirrus Data team was also able to migrate those using the Cirrus Migrate Cloud solution. The combination of a local data center high speed initial seed of data and remote migration delta catch-up strategy led to a successful and smooth migration of all 2.5 PB of data in 7 months. The energy company’s critical databases and applications were safe in its own data center with nearly zero downtime—and the next project with Cirrus was already being discussed.
