At first blush, F5 Networks' new Synthesis Architecture for Software-Defined Application Services might appear to compete with new offerings from Cisco and VMware. But no, F5 CEO John McAdam and executive vice-president of Strategic Solutions Manuel Rivelo tell IDG Communications Chief Content Officer John Gallant that F5 is very much in sync with these two data center giants (we did not, however, press them on the relationship between Cisco and VMware).

The Grill: Gino Pokluda gains control of an unwieldy database system

Gino Pokluda had a problem: The database system at Presbyterian Health Plan in Albuquerque, N.M., where Pokluda serves as manager of service improvement and innovation, was becoming increasingly expensive and unwieldy, requiring about 80TB of storage for 13 database environments. To gain control, Pokluda implemented Delphix software to enable agile data management and eliminate redundant infrastructure. The 2012 project sliced his storage needs to 35TB, even though his team now maintains 23 environments. Here Pokluda, who manages all production, test and development environments for the company, discusses the database system overhaul and shares other IT management insights.

UEFI president: We need more key providers

Since its introduction, the Unified Extensible Firmware Interface has created a fair amount of controversy. UEFI was created through an industry consortium as an evolutionary step up from BIOS, the simple firmware long used when starting a computer to initialize all the components and load the operating system. Among its advanced features, UEFI includes an option called Secure Boot, which requires that any software used before the operating system starts, or after it shuts down, has been signed by a certificate authority.
