An everRun Enterprise system requires two x86-64 host servers that can support multiple virtual machines (VMs), and a remote management computer (that is, a general-purpose PC) that can run the everRun Availability Console.
everRun Enterprise System Hardware requirements are described below. See System Software for software requirements.
Stratus everRun Enterprise software will run on any systems listed on the Red Hat® Linux Hardware Catalog that contains one of the following:
A second computer with identical processors is required for use as a redundant server for Protected Virtual Machines (or PVMs—virtual machines that are protected by Stratus everRun software). The CPUs for every host computer must have hardware support for virtualization enabled in the BIOS.
A minimum of 8 GB of RAM (physical memory) is recommended.
Only internal disks are supported. A minimum of two drives per physical machine is required for fault-tolerant operation.
50 GB is required for the host CentOS operating system and everRun software in the host domain including space for logs. Allow 10 GB minimum (boot disk) for each VM. Additional storage is needed for applications and data on each VM.
The minimum network configuration includes two ports: one for A-link and one for a shared management/business link.
An optimal network configuration includes two 10-GbE network ports for A-Links (one of which also serves as priv0, the private network), a network interface for the management network, and as many business/production ports as your protected VMs may need. If planning to run multiple protected VMs, consider adding pairs of A-Links, up to the supported total of four pairs.
All network components in a SplitSite configuration must have more than 155 Mbps minimum capacity, end-to-end. When fault-tolerant SMP is used, the A-Link networks must be a minimum of 1Gbps.
See Network Architecture Overview, A-Link and Private Networks, and Business and Management Networks for more information.
Each everRun Enterprise host must have a static IPv4 IP address assigned for use by the management software. Obtain IP addresses for DNS primary and secondary servers, and gateway and subnet mask information for your management network, from your IT network administrator. See Obtaining System IP Information for more information.
everRun systems use port 443 in the local firewall for HTTPS communications, port 22 for ssh, and 5900 for VNC with Linux VMs. Firewalls must allow traffic through the appropriate ports. Firewalls must permit everRun-protected VMs to contact quorum service computers using UDP port 4557.
