Shared storage
Figure 2-2 Four clusters on two x440s running VMware with shared storage
Dual-chassis eight-way configuration can be used as clustered database servers and/or application servers in an ERP/CRM/SCM environment, delivering high performance, high availability, and reliability, which are key requirements of enterprise applications. This configuration requires an external storage enclosure or SAN, depending on the size of the database, which is driven by the number of users.
2.2 Why choose the x440
There are some good reasons to choose the x440 as your mission-critical Intel platform. In this section we describe the major benefits of x440.
