IBM Systems and Technology Group EMC’s CX 4 Value Propositions § Take cost out IBM Systems and Technology Group EMC’s CX 4 Value Propositions § Take cost out of the business without sacrificing performance and scalability by consolidating twice the workload in a single system—optimizing storage capacity—and by protecting investments. Check DS 5000 benchmarks for performance superiority with mixed workloads SAP, Exchange, Oracle. Best TCO with excellent ROIDS § The CLARii. ON CX 4 series’ power-saving technologies help manage energy consumption and consolidate data storage. DS 5000 wins SPC-1 and SPEC-2 benchmarks with energy cost savings. It can mix SATA and FC workloads for balanced performance § CLARii. ON CX 4 systems provide industry-leading availability and protection by combining CLARii. ON’s proven Five 9 s availability with built-in support for concurrent local and remote (CLR) replication. All vendors claim Five 9’s. DS 5000 does not suffer from issues like “Write Cache Disablement” due to a failed drive in the first enclosure, “Write Cache Disablement” due to a failed power supply, or Loss of back-end due to unexpected loss of a FC loop. § CLARii. ON’s unique hardware and software capabilities and integration with VMware extends the value of virtualized server environments. DS 3000, DS 4000, and DS 5000 all support VMware.
