Blade servers solved the problem of density for businesses, but they did so with compromises that limited their appeal for many applications. As complexity of both applications and environments grew, blade infrastructures were limited in their effectiveness for the task. Customers were relegated to lower-density rack servers for their more scalable applications. And while purpose-built systems allowed a business to tailor to their specific needs, they created more management complexity.
New flexibility is required to allow modular blade architectures to keep pace with the types of applications that customers need to drive a more agile business. The IBM Flex System X6 family of compute nodes are worth serious consideration for businesses trying to balance the needs of this new generation of agile applications with the desire for more standardization and modularity to hold down total cost of ownership (TCO).
