Why is now the time to migrated from your proprietary RISC/UNIX platform to Cisco UCS with Red Hat 
Enterprise Linux. There are several reasons: Technology transitions are driving new demands on data center and IT infrastructure. These new applications and computing models have standardized on x86 architecture while aging RISC/UNIX infrastructure doesn’t provide the performance or the flexibility required to support the needs of the business. IT departments may also be experiencing the pain of RISC/UNIX maintenance and software licensing costs while their budgets are flat or shrinking. At the same time, overarching uncertainty about RISC/UNIX futures foreshadowed by rapidly declining market share combined with dropped hardware and software support. According to the most recent IDC Q42014 server tracker, RISC revenue has dropped 40% from 2012 to 2014 while Cisco UCS revenue has increased 80%.
Cisco and Red Hat are industry leaders with vast mission-critical application experience. We understand the scalability, security, availability, and reliability requirements of mission-critical applications in the data center. I urge you to watch this new webcast as we reveal the reasons behind why making the migration from RISC/UNIX to Red Hat Enterprise Linux on Cisco UCS is essential for those wanting to improve the effectiveness, functionality, and efficiency of their data centers.
Cisco UCS provides a great platform for migrating RISC/UNIX specific applications using RHEL.
Cisco IT migrated all of our mostly-Unix mainframe Oracle ERP apps to RHEL on UCS starting in 2010.
Moved our $48B/year “Quote to Cash” suite of apps from 4 Risc-based systems (running Oracle RAC 9i on HP-UX) to 4 UCS blade servers (running Oracle RAC 10g on RHEL) in 2011.

Moved our 40 TB Customer Care suite, one of the last of our Oracle suites, from 3 Superdomes (2 E10Ks, one E7K) to a 12-node Oracle RAC on 12 UCS blade servers on RHEL in 2012.

Migrating to UCS blades gave us better performance and lower power / space footprint. Most of all it gave us horizontal scaability – adding another blade is far easier than adding another mainframe.
