This page provides the requirements you must be aware of before installing the product.
Software requirements
The macro unmigrated-inline-wiki-markup from Confluence is no longer available.
components are virtual machines designed to run on the following virtualization platform (hypervisor) products only:
- VMware ESX/ESXi 5.x
- VMware ESX/ESXi 4.x
- VMware ESX/ESXi 3.5
Note
For component instances using more than 4 GB of memory, you must use VMware ESX/ESXi 5.x. You can also use VMware ESX/ESXi 4.x, but it must be the Enterprise Plus version. Contact VMware Support for more information.
Hardware requirements
Server hardware and hypervisor must support 64-bit guests.
Each instance of the various

components has minimum resource requirements:
Minimum resource requirements per component instance
* An additional 100 GB minimum is recommended for storing traffic data
Recommendations
- While recent hypervisor products are able to manage resource allocation dynamically, it is important not to over-allocate processor and memory resources. It is also important to remember that the hypervisor itself has resource requirements. Therefore, if a given host has 32 GB of memory, for example, and you deploy components which together have requirements approaching 32 GB, you can expect problems.
- To optimize the performance of a component, you can increase or decrease resource allocations. If performance is unsatisfactory, for example, you can add extra processing power or memory.
Note
Host-hardware and memory latency can limit performance.
Storage requirements
The following components have storage requirements:

Recommendation
Before installing the Analyzer instance, create the data disk with VMware tools. If you change the size of a pre-existing disk, do so before you switch the power of the virtual machine on.
Warning
You can change processor, memory, and network adapter allocations any time during the life of the component instance. However, for data storage, if you change the disk, data collected to date is deleted.

). This data is stored "off board" on a device such as a network-attached storage (NAS) system. The minimum useful storage allocation is 1 TB

instances implies a higher volume of incoming data, so a larger storage allocation might be warranted.
Supported protocols to serve NAS:
The management of storage space is based on a rolling-buffer data structure (first in, first out – FIFO). Once a storage disk reaches its maximum capacity, new data overwrites the oldest data.
Network requirements

components are network devices interconnected to form a system. In addition, access to the interfaces of these components is achieved via the web. To avoid network-related performance issues, you must take certain configuration and infrastructure details into consideration when planning an installation.
For example, the system works best when you deploy components on the same host. Where a common host is not possible, optimize the communications links between components. Similarly, the connection between
