A Cost-Effective Mechanism
Citi is a global provider of consumer, corporate and investment-banking products and services. Its many brands include Citibank, CitiMortgage, Citi Cards and Women & Co. Citi operates in more than 160 countries and handles around 200 million customer accounts. With such a large presence, you’d expect it to have a large IT infrastructure, and it does. It runs servers of all types, including IBM mainframes and Power Systems*, Linux* (stand-alone on System z*), Windows* and UNIX* OS-based machines. These boxes handle core functions: serving customer accounts, running businessintelligence applications or supporting internal back-office accounting functions. They all produce a huge amount of data, most of which is backed up, stored and ready for recovery for regulatory or internal purposes. This data is vital to Citi’s everyday operations. That’s why the company put so much effort into creating a seamless data-retention model: from point-of-origin to vaulted storage. But things weren’t always so efficient, as Kennedy explains. “Back in 1996, we were dealing with our first large data warehouse with around 20 terabytes of data, which was large for that time,” he says. “We would have to break backups into 20 separate components, 20 separate servers and 20 separate tape libraries. We only had one window in which to do that, typically on Sunday afternoons: the only time we could take a machine down for system backup. We struggled with that quite a bit.” That’s probably an understatement given the scale of the organization and the growth in the amount of data it was collecting. Network bandwidth, for example, became an issue, forcing Citi’s IT staff to tune the network continuously to accommodate increased traffic. This affected everyday operations as data

movement competed with typical application transactions. “We revisited our backup architecture,” Kennedy recalls. “As a result, we considered using INNOVATION tools, including FDR/UPSTREAM and UPSTREAM/SOS, both of which would allow us to move data in a more robust environment. No sooner had we converted to EMC and INNOVATION than our issues related to backups almost literally disappeared.” These improvements resulted in part because a SAN fabric and transfer devices had been introduced into the storage environment. Using this SAN, Citi IT staff could bypass the production network and run backups whenever they were scheduled, without worrying about a network bottleneck and reduced application response times. This also held true with its Linux on System z instances, with UPSTREAM/ SOS passing these mainframe-

based backups over System z FICON* and Fibre Channel Protocol (FCP) channels rather than over the network. Ordinarily FDR/UPSTREAM pushes distributed backups to mainframe-based tape or DASD, but
