Dell Minimum Hardware List and System Requirements
Oracle provides some general guidelines for minimum hardware and soware requirements. These include:
• External shared storage
• At least 256 MB of RAM on each node (512 MB preferred)
• Oracle supported clusterware. In Oracle9i, Oracle supports a variety of OS dependent clusterware on dierent plaorm
However, for Windows Server, Oracle provides the clusterware. For Oracle9i on Windows, Oracle can manage shared storage by
either accessing raw disks, or by using the Oracle Cluster File System (OCFS). For Oracle10g, both raw disks and OCFS are sll
supported. In addion, Automac Storage Management (ASM) oers automated management of shared disks.
Oracle provides a list of cered hardware conguraons on the Metalink website, hp://metalink.oracle.com.
Dell oers some specic guidelines for implemenng Oracle RAC. These guidelines can be viewed on the Dell website, hp://www.
dell.com/oracle . The following is a synopsis of the minimum hardware requirements for Dell hardware congured for Oracle RAC:
1. Dell PowerEdge system (two to eight nodes using OCFS or two to four nodes using raw devices).
2. Intel Penum III processor, 700 MHz or higher
3. 512 MB RAM
4. Integrated SCSI adapter or PERC 3/Dx controller for internal hard drives
5. One 36- or 73-GB hard drive connected to integrated SCSI adapter or two 36- or 73-GB hard drives (RAID 1) connected to
a PERC 3/Di controller
6. Two NICs (three for redundant interconnect opon)
7. Gigabit Ethernet switch (two for redundant interconnect opon)
8. Dell | EMC Fibre Channel external storage opon
a. Dell | EMC CXx00 bre channel storage array with one DPE2 storage processor unit and oponal DAE2 disk
expansion units
b. At least three LUNs of 5 GB each
c. Qlogic or Emulex opcal HBA (Host Bus Adapter) – two if using PowerPath soware
d. Dell | EMC Fibre Channel switch (two if using PowerPath soware)
i. Eight ports for two to six nodes
ii. Sixteen ports for seven or eight nodes
iii. No switch is required for the two-node direct aached storage opon
e. Fiber opc cables between HBAs and switch ports, and between switches and the CXx00 Storage Processor ports
9. Dell PowerVault SCSI Array external storage opon
a. Two nodes only
b. Dell PowerVault 22xS storage system
c. Two enclosure management modules (EMMs)
d. At least one logical drive congured as RAID 0, RAID1, RAID 5 or RAID 10. Dell recommends RAID10.
