Alert Logic Requirements for Virtual and Physical Appliances

Requirements for Alert Logic virtual appliances

The following table describes the basic system requirements to install a virtual IDS appliance:

Components System Requirements
CPU 4 virtual CPUs
RAM 8 GB
Disk space 40 GB minimum
Supported virtual environment VMware only
Encryption TLS Standard (SSL): 2048bit key encryption, 256bit AES bulk encryption

Bandwidth volume directly impacts the ability of the appliance to inspect traffic. Therefore, high traffic environments may require a virtual machine with additional processor and memory resources.

If you want to run scans, consider 8 virtual CPUs (cores) and 16 GB of memory.

Physical appliance

The following describes the basic requirements to install a physical appliance:

Components System Requirements
CPU Intel Xeon
RAM 4 GB DDR3
Disk space 500 GB
Chassis 1U rack mounted
Power 250W
Encryption TLS Standard (SSL): 2048-bit key encryption, 256-bit AES bulk encryption

Requirements for Alert Logic Web Security Manager Premier appliances

VMware virtual appliance

The following table describes the basic system requirements to install a VMware virtual appliance:

Components System Requirements
CPU 2 CPUs 64 bit
RAM 4 GB
Disk space 250 GB
Virtual network interface(s) An interface with an external IP address for management
An interface with access to the web servers to be protected
Encryption / Decryption for SSL traffic AES-NI CPU instruction set for encryption/decryption of SSL traffic on VMs and host OS is recommended
Clustering For clustering to work, make sure promiscuous mode, forged transmits, and MAC address changes are allowed on the VMware virtual switch (vSwitch) or the port group in the VMware ESX network configuration

Processing Capacity

The following table describes the bandwidth limits for the Managed WAF physical appliances:

Appliance type Throughput Number of virtual hosts Number of SSL certificates Number of proxies
Tier 1 - R410, R220, R230 0-250 Mbps 1000 100 200
Tier 2 - R630 250-1000 Mbps 1000 100 200

This is the recommended basic configuration for the Web Security Manager product when deployed on a virtual appliance. Bandwidth volume directly impacts the ability of the appliance to inspect traffic. Therefore, high traffic environments may require a virtual machine with additional processor and memory resources.

If you want to enable scans, the recommended configuration is 8 virtual CPUs and 16 GB of memory.

Physical appliance

The following describes the basic requirements to install a physical appliance:

Components System Requirements
CPU Intel Xeon
RAM 4 GB DDR3
Disk space 500 GB
Chassis 1U rack mounted
Power 250W
Encryption TLS Standard (SSL): 2048-bit key encryption, 256-bit AES bulk encryption
