Chapter 1 Selecting Your Hardware Components This document provides information for selecting hardware. Note that this document is current with supported information for Dell PowerConnect W-AirWave 7.6.
The following table lists the minimum specifications required to run AirWave. Table 2: Minimum CPU, Memory, and Storage Devices CPU RAM (GB) Disk Config IOPs Storage (GB) Less than 500 Any 4 Any 30 75 500 Intel Core i3 550 @ 3.20GHz 8 4x 146GB 15k RAID 10 300 273 1000 Intel Xeon E5-1603 @ 2.8 GHz 16 6x 146GB 15k RAID 10 600 410 1500 Intel Xeon E5-2640 @ 2.50GHz 32 6x 146GB 15k RAID 10 900 410 4000 Dual Intel Xeon E5-2640 @ 2.
Choosing Your RAID Controller RAID 1+0 is the ONLY supported RAID configuration for AirWave. NOTE: Software RAID and SATA drives are NOT SUPPORTED for any configuration of AirWave. RAID Configuration Information For RAID 1+0: l Dedicated Hardware RAID controller with caching and battery backup or non volatile (NV) cache. l RAID controller should be configured for Write-Back caching with battery backup (unless NVcache is selected, then Force Write-Back without Battery backup is recommended).
A minimum of six (6) Enterprise SSDs in a RAID 1+0 configuration are required, (Refer to "CPU, Memory, and Storage Matrix" on page 1 for minimum needed storage capacity information.) Eight (8) or more SSDs in a RAID 1+0 configuration are recommended. The target random write 4KB IOP Performance is at minimum 3,000 sustained IOPS for 5,000 device monitoring. The actual disk IOP requirement can vary depending on the configuration of the AirWave server.
Chapter 2 Configuring Your Hardware This section explains sizing information for the following topics: l "CPU Configuration " on page 5 l "Disk Partitioning" on page 5 l "File System Configuration" on page 5 CPU Configuration Ensure that Power Management is configured for Maximum Performance. By default, most vendors configure BIOS to an eco-friendly setting. Ensure that Memory Operating Mode is configured to Optimizer Mode, if available.

Chapter 3 Virtualization and Scalability This section includes the following topics: l "Virtualization" on page 7 l "Scalability Assumptions" on page 7 Virtualization AirWave can run in a VMware and Xen virtualized environment. To ensure scalability, dedicate the processing and memory. You must also ensure that the disk subsystem can maintain the IOPS throughput as detailed below.
NOTE: Auditing more than once a day can have a tremendous impact on scalability.
