In Sviaz-Bank transferred 250 virtual machines to new infrastructure

The CROC company upgraded virtualization infrastructure in the Sviaz-Bank (group of Vnesheconombank) without stopping of business processes and expansion of data center of the customer. The project allowed to increase twice performance of computing resources that provided higher speed and stability of work of systems, critical for bank, and infrastructure applications of the customer.

Virtualization of computing resources — already traditional method of increase in efficiency of use of hardware infrastructure. And here the systems of virtualization, servers and storage systems constantly develop. Their obsolescence and reduction of functionality can be the cause of deterioration in work of business services.

As a result of a gain of the customer base, expansion of a branch network and start of new Internet services in bank there was a need of considerable expansion of opportunities of infrastructure.

CROC upgraded the virtualization platform on two geographically distributed computing platforms, one them which it is placed in one of DPCs of network of data centers of CROC since 2011. Updating only of program components of the virtualization platform in this case would be insufficient as the available hardware resources did not support new opportunities of software.

Specialists of CROC designed almost from scratch new infrastructure and transferred to it all 250 existing virtual machines (VM) without stopping of work of services of bank. Migration of especially critical and high-loaded VM was performed at night to reduce possible risks and extent of influence on work of bank services. Within the project software products of VMware, servers of Hewlett Packard Enterprise (HPE) and EM disk arrays were used
