Uptime and data protection applies to hundreds of virtual machines as opposed to dozens of physical servers.\r\n•        With CLARiiON and VMware, service-level management can be enforced by combining EMC Navisphere Quality of Service Manager and VMware Distributed Resource Scheduler (DRS). (See white paper for more information.)\r\n        3PAR does not offer any level of quality of service.\r\nHow to Handle 3PAR Competitive Claims\r\nObjection:        “3PAR is easier to use than CLARiiON.”\r\nResponse:         EMC Navisphere Task Bar provides customers the ability to provision storage with a few simple clicks. Furthermore, CLARiiON CX4 series provides the option to provision standard RAID to ensure top performance for Tier 1 applications as well as ease of use with CLARiiON Virtual Provisioning. 3PAR does not provide the option to guarantee performance.\r\nObjection:        “3PAR gives you the ability to save on storage utilization with Thin Provisioning.”\r\nResponse:         CLARiiON CX4 series offers CLARiiON Virtual Provisioning, and also provides the option to provision standard RAID Groups for those applications that require guaranteed performance. 3PAR cannot do this. \r\nObjection:        “3PAR has better scalability.”\r\nResponse:         The CLARiiON CX4-960 scales to 960 drives and 960 TB. Although 3PAR’s S800 model scales to 1,280 drives, it is still limited to a maximum of \r\n600 TB.\r\nAdditional Resources\r\nFor competitive help, use these resources:\r\n•        Powerlink’s 3PAR page \r\n•        “White Paper: Maintaining End-to-End Service Levels for VMware Virtual Machines Using VMware DRS and EMC Navisphere Quality of Service Manager”\r\nIf you have questions, contact your EMC Account Manager or local channel management team. \r\n
