13、larger, slower disk drives Sizes Quarter rack, half rack, and full rack Greenplum also announced a “high performance” model using SSD rather than disk drives, but so far it has not materialized.,Greenplum DCA,40U Cabinet,Moving from half to full rack can only be done onsite by the EMC field team,Gre
14、enplum DCA High Capacity Model,Same 40U Cabinet,The only difference is capacity and scan speed. The simply replaced the drives in the DCA with larger capacity, slower drives!,What is the EMC Greenplum DCA,Applications access the database through the master host. If the master is down, the system is
15、inaccessible since no automated connection failover,No “magic” here, the data needs to be moved from disk, to the CPUs for processing,Only one port for application connections, this limits throughput,What is the EMC Greenplum DCA,The standby is kept in synch with the primary using disk mirroring. If
16、 this is synchronous, that hurts performance, and if asynchronous then transactions can be lost in the event of a failover,Greenplum Claims These Advantages,HANA delivers far simpler administration, better compression, and faster performance than Greenplum,Being able to store 100TB, and access and return it quickly and efficiently, are two completely different things,The architecture is full of bottlenecks and inefficiencies in its design (discussed later),Greenplum DCA Comparison Summary,Agenda
