But the fact is that both DW Appliances and Exadata reduce the overall cost of ownership in many applications. Oddly enough, in Exadata’s case, this is partially thanks to a reduction in the number of Oracle database licenses necessary to support a given workload. We have seen several situations where multiple hardware platforms were evaluated for running a company’s Oracle application and have ended up costing less to implement and maintain on Exadata than on the other options evaluated. High Availability: Most DW Appliances provide an architecture that supports at least some degree of high availability (HA).
The quarter-to-half upgrade includes two database servers and four storage servers along with an additional InfiniBand switch, which is configured as a spine switch. The half-to-full upgrade includes four database servers and seven storage servers. Eighth-to-quarter upgrades do not include any additional hardware because it was already included in the shipment of the eighth rack. This upgrade is simply a software fix to enable the resources that were disabled during the initial configuration of the eighth rack.
To date, this is the one piece of the package that Oracle has agreed to allow customers to replace. If you have another switch that you like better, you can remove the included switch and replace it (at your own cost). Models prior to the X3-2 included a KVM unit as well. Due to the larger database server size in the X2-8, X3-8, and X4-8, no KVM is provided. Beginning with the X3-2, Oracle has removed the KVM in favor of leaving the top two rack units available for top-ofrack switches. The package price also includes a spares kit that includes an extra flash card and an extra disk drive.
