Index Server Requirements and Storage

The index server is responsible for indexing or cataloging all items so the data can be searched by administrators or email users. The following requirements apply to the index server and are recommended for optimal performance.

Processor

8 cores (or processors)

Memory

32 GB RAM

Network

GB Ethernet

Storage

Two different spaces must be set up for storage.

Storage 1: Operating System

150GB on local disk for OS, applications, and swap space (VM is delivered with this volume, thin-provisioned).

Storage 2: Index Content
  • Adequate attached storage for indexes.
  • Fiber Channel (FC) connection to a SAN is recommended.
  • iSCSI connections are supported, but performance cannot be guaranteed.
NOTE
A single index is sufficient for deployments of 4,000 users or fewer. For larger deployments, please contact your Support Representative for sizing recommendations.

VMware
  • ESX 5.5 or greater
  • Vmotion supported
  • Thin provisioning supported; thick is suggested
  • VMFS (RDM not required, but suggested for better performance)
  • Disk caching on disk array

Hyper-V
  • Hyper-V Server 2012 and higher (Hyper-V 2012 R2 recommended)
  • Thin provisioning supported; thick is suggested
  • Disk caching on disk array
