"Consolidation drives value." "Manage less and do more."
These initiatives, and many others like them, make sense from a financial standpoint, but can often lead to sleepless nights for operations managers once they realize the majority of their business, sometimes as much as 85%, is now run out of a single datacenter or a single platform. What happens when the system goes down? What happens when my datacenter loses connectivity? How quickly can I recover from an outage? Do I even need to recover, can I just roll-over to an active or passive backup?
Many mission critical core business applications, from larger vendors such as SAP and their ERP solutions, are run in datacenters much like this. However through high-availability and disaster recovery (HADR) capabilities provided by IBM, these datacenters can establish a failover policy to prevent even the slightest interruption to your company’s centralized business processes and financial systems.
IBM’s core HADR capabilities are provided by the Tivoli System Automation family of products, which we’ll specifically touch on System Automation for Multiplatforms here. Tivoli System Automation for Multiplatforms (SA MP) is a high availability clustering solution with advanced automation capabilities. It includes out-of-the-box resiliency policies for many IBM products delivering mission-critical capabilities to our customers. SA MP is the default, built-in HADR solution for IBM DB2 for Linux, Unix, and Windows available at no extra charge to DB2 LUW customers. The expansive capability of System Automation to provide a single point-of-view into your HADR capabilities and manage them, whether your fail-over datacenters are across the street or across the continent, provides immense value to our customers in managing their heterogeneous environments.
One such customer leveraging these out-of-the-box policies from SA MP for DB2, and by extension SAP, is China Ocean Shipping (Group) Company. For a detailed overview of the entire solution implemented by COSCO, including IBM POWER hardware capabilties, please follow the link below. In this post, I’ll briefly touch on how COSCO was able to leverage HADR capabilities to prevent major damage to the business during multiple datacenter outages. COSCO consolidated much of their business operations onto a single SAP ERP solution, but required the highest levels of service availability from this single system. By putting their SAP solution on top of DB2 and leveraging the HADR capabilities provided by SA MP, this customer was able to deploy a single SAP ERP solution across multiple datacenters worldwide, offering near real-time replication. These HADR capabilities and benefits were fully realized multiple times when the customer’s main datacenters experience prolonged outages, including the historic 2011 Tōhoku earthquake. They were able to seamlessly switch over from their datacenter in Tokyo to the off-site datacenter in Beijing, with virtually no service interruption.
Now the actual definition of “disaster recovery” may not always come to mind when you are planning your HADR strategies, but Tivoli System Automation, along with the many other IBM products it is embedded in are available to minimize your key HADR metrics, both recovery point objective (RPO) and recovery time objective (RTO). Many additional policies are available for other IBM and third-party products to monitor and ensure the availability for your business services.
