VCE holds the #1 market position for Integrated Infrastructure Systems, with 46 percent, according to Gartner. The Vblock 540 system(one member of the VCE group) delivers an agile and resilient system to ensure that enterprise class services are delivered without compromising service levels.The enterprise-class Vblock system 540 is durable and fully redundant,ensuring the highest levels of availability for critical applications and resources.The system incorporates EMC XtremIO storage, with vastly improved data efficiency. It is an agile, intelligent, and resilient system. It uses dynamic and intelligent capabilities to guarantee required application performance levels. Coming to the components of Vblock 540 systems, following are present :-
As we can see above that XtremIO forms the storage part of Vblock 540 while XtremIO Data Protection (XDP) is a technology whose primary function is to protect data from SSD failures while allowing failed devices to remain in place using XDP’s “hot space” feature until a convenient window is arranged. This helps in the protection of Oracle data to a greater extent. Should a subsequent failure occur, XDP’s hot space feature will simply utilize remaining
In Vblock 540 we use VPLEX deployment options for business continuity, resilience, scale out cluster architecture and data mobility. It helps in protecting the oracle database from operating system, network, and hardware related problems via VMware vCentre Server Heartbeat. It is a clustering solution with primary and secondary nodes operating in active-passive mode. It keeps the vCentre Server instances synchronized. The Vblock and VPLEX solution is demonstrated in Figure 1.

Below are some Failure Scenarios which are being taken care by the VPLEX solution.
In summary, there are many solutions by which the resilience is enforced in the Vblock solutions. In this blog, we talked about VPLEX, vsphere and other storage solutions which is basically XtremIO. There are other components within Vblock 540 which enforces resilience. The most fascinating and important point is that the sanctity of oracle database in Vblock 540 is maintained by all the hardware,software and virtualized components of Vblock as mentioned above.
