In the age of e-commerce, competitors are literally a click away. And if you can't fulfill an order, customers may be able to cancel it with a click as well. Operating in this environment, Strategic Fulfillment Group, which provides order fulfillment services—from order taking through to picking and shipment—to a number of customers, can’t afford to lose access to its data and applications. No exceptions.
Strategic Fulfillment Group (SFG) considers itself to be a medium-sized company, but you wouldn’t know it from its IT environment. The company employs multiple IBM i-based Power Systems servers with multiple partitions. Those systems run a collection of thousands of in-house developed applications, as well as purchased software that has been integrated into the company’s IT systems.
One of SFG’s major selling points is that it delivers its services through a single relational database. The primary benefit of this is that customers, which SFG views as partners, can expand into new lines of business without having to worry about the complexities of integrating data from different databases for different company divisions.
SFG’s central database contains millions of names and addresses. In total, there are about 14-billion records, and growing. SFG also makes considerable use of IBM i’s Integrated File System (IFS).
SFG’s business environment demands an exceptionally high level of data and application availability. Yet finding a way to ensure near-zero downtime and zero data loss in such a large and complex IT environment was problematic.
Syncsort is the premier provider of disaster recovery (DR) and high availability (HA) solutions for IBM i. It offers reliable, high performance HA/DR solutions that fulfill the needs of practically every organization, no matter how large, complex or unique its IT environment may be.
Being a mid-sized IBM i shop, SFG initially chose iTERA Availability, Syncsort’s IBM i-based HA/DR solution designed for small to medium-sized businesses (SMBs). However, the company’s database was as large, its use of IFS as extensive, and its systems as complex as those of far larger companies. Consequently, in consultation with Syncsort’s, it was determined that MIMIX Availability with its MIMIX Global add-on for multi-server HA/DR would better provide the enterprise level performance and scalability required by SFG’s environment and high transaction volumes.
Syncsort then helped SFG to migrate to MIMIX Availability. “From the beginning, Syncsort’s greatly impressed us with its commitment to us,” declared John Trotter, Director of Information Services. “They really stepped up to the plate.”
MIMIX Availability leverages IBM i’s advanced remote journaling features, along with other change capture and replication mechanisms, to transparently replicate applications, data and system state information in real time from a production server to a recovery server. MIMIX thus ensures that the recovery server is always a complete, ready-to-run replica.
Two of SFG’s Power Systems servers host seven logical partitions that serve the business’ operational needs. This includes two clusters of three logical partitions. One cluster includes web server LPARs. The other includes the production LPARs where the backend database and all of SFG’s customers’ data reside.
SFG uses MIMIX Availability to replicate from the production partitions on each server to backup partitions on the other server in real time. Should either server become unavailable, the other can quickly assume the full production load. SFG also takes advantage of MIMIX’s data protection reports to ensure that what the company wants to be replicated is indeed being replicated.
These servers are separated by about 25 miles. Thus, even if a disaster should knock out one of the sites, full operations could resume at the other site with almost no interruption.
Just how short is “almost no interruption?” Trotter has a precise answer. SFG has performed role swaps. During one of those swaps, web cluster downtime was only four minutes and nine seconds. SFG thus sees MIMIX Availability as an invaluable way to prevent disruptions of its partners’ business operations.
As pleased as he is with MIMIX Availability, Trotter is particularly impressed with the service and support he receives from Syncsort. “I’ve worked with IBM equipment since I was a junior trainee in 1969. And I would put Syncsort’s customer service and technical support at the highest echelon of any vendor I’ve worked with.”
