Founded in 1991, Bank V is the largest commercial bank in Russia’s Far Eastern region. The bank has been expanding its business rapidly through a series of mergers and acquisitions. It now has more than 700 branches across 10 federal subjects.


Bank V expanded its business through mergers and acquisitions, solidifying its leadership in Russia’s Far East region. The bank’s latest effort drove its business volume from 65 to 93 percent, which resulted in sluggish response times for some of its systems.

To prevent business disruptions and data losses from causing customer attrition, Bank V was in urgent need of reliable, high-performance IT systems. The bank’s leadership had to ensure operation efficiency and stability, and continue to meet growing business needs over the next five years.



Bank V used four OceanStor Dorado all-flash storage arrays, deploying two in the same data center. Huawei established a gateway-free active-active data center solution (with two data centers located 40 km apart) to host the bank’s core transaction systems. A single Dorado storage system delivered an 8-fold improvement in efficiency and will easily meet Bank V’s requirements over the next five years with 400,000 IOPS at 1 millisecond of latency. Its gateway-free active-active design ensures 24/7 business continuity.

High Performance and Stability for the Next Five Years of Growth

A series of mergers and acquisitions has placed intense pressure on Bank V, including its 2016 merger with Uniastrum Bank, which greatly expanded its user base and drove its business volume from 65 to 93 percent. The bank needed to consolidate its Automatic Banking System (ABS) with Uniastrum Bank’s core systems, which would increase business system management complexity by 40 percent. These changes posed great challenges to Bank V’s IT systems.

“This large-scale merger led to a sharp increase in our IT systems’ workload,” Bank V IT director said. “Some customers were experiencing slow response times when using loan systems. We also worried about our IT devices’ performance and stability when a large number of customers were using the transaction system at the same time. Although we had configured DR protection for our two data centers, system switchovers could still have disrupted business for several hours and caused data losses if a fault had occurred at our production data center. This would have lowered our customer satisfaction and could even have led to attrition.”

Bank V IT director continued, “Our previous storage systems could not fulfill the Central Bank of the Russian Federation’s regulatory requirements. We needed to upgrade our existing IT architecture to ensure high performance and provide the necessary stability and reliability for our IT business systems.”

CFT, the leading ISV in Russia’s financial industry, is a business provider for Bank V’s ABS. CFT acted as a consultant for Bank V’s IT upgrade, proposing standards and IT planning requirements for the next five years, based on the bank’s status quo and pace of development — a performance of 400,000 IOPS at 1 millisecond of latency — and a target of zero disruption for its core business transactions.

Huawei provided gateway-free active-active all-flash storage, but Bank V required POC test results before deciding on Huawei’s solution. The bank designed 15 business models for testing device performance on the live network, and planned on using two storage devices for achieving 400,000 IOPS at 1 millisecond of latency. However, one single OceanStor Dorado storage system provides 410,000 IOPS and ensures no more than 1 millisecond of latency.

To handle its rapid expansion, Bank V attached great importance to the system’s performance. Huawei’s OceanStor Dorado delivers stable performance when creating frequent snapshots, switching services between active-active storage systems, reconstructing data after disk failure, and during de-duplication and compression. This is true even when snapshots are created several times each week for testing and developing merger and acquisition business systems. Huawei’s OceanStor Dorado provided 35 percent higher performance than the competition’s new flash solution.


Gateway-Free Active-Active Design Ensures 24/7 Business Continuity

If a fault had occurred under Bank V’s existing dual-center architecture, data would have been lost and business would have been disrupted for several hours. Losing core business data is an unacceptable outcome, and lengthy disruptions severely affect customer satisfaction.

Huawei’s Dorado all-flash storage significantly improves performance, and its industry-leading all-flash active-active architecture prevents disruption or data loss and ensures 24/7 business continuity. Huawei’s active-active data center architecture can even achieve 400,000 IOPS at 1 millisecond of latency when its two data centers are 40 kilometers apart, which eliminated Bank V’s concerns.

5:1 Data Reduction Guarantee Reduces TCO by 50 Percent over Five Years

Bank V’s expansion strategy promotes rapid growth, but consumes large amounts of funds. The institution needed to control costs after merging with Uniastrum. Huawei’s OceanStor Dorado leverages inline de-duplication and compression to deliver outstanding performance and improve space utilization. The solution reduces power consumption and cooling costs while greatly lowering construction and O&M expenses, which will lower Bank V’s TCO by 50 percent over the next five years.

Huawei’s OceanStor Dorado all-flash active-active solution’s superior performance, high reliability, and 24/7 business continuity more than satisfied Bank V’s high demands for business development.
