System Requirements Overview
A ztC Edge system can support multiple virtual machines (VMs) and a remote management computer (that is, a general-purpose PC) that can run the ztC Console.
ztC Edge System Hardware
For information on guest operating systems, see Compatible Guest Operating Systems.
System Hardware
RAM
Each PM has 32 GB of RAM (physical memory).
Disk Space
Each PM contains a 512 GB solid-state drive (SSD), of which approximately 475 GB is available for VMs.
Network
Each PM has four 1-Gb Ethernet ports, including:
- On systems licensed for two nodes:
- A combined A-link and priv0 private network port, labeled blue (•)
- A second, dedicated A-link port, labeled yellow (• •)
- On systems licensed for two nodes or one node:
- A combined business network and management network port, labeled P1
- An optional business network port, labeled P2
The system also supports Intel® Active Management Technology (AMT) lights-out support, which you can access over the P1 port of each PM.
ALSR configurations have different network requirements. For information, see Meeting Network Requirements.
See Network Architecture, A‑Link and Private Networks, and Business and Management Networks for more information.
IP Addresses
Each ztC Edge system 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.
Ports
ztC Edge systems use port 443 in the local firewall for HTTPS communications, port 22 for ssh, and 5900-59nn for each active VNC associated with each VM. Firewalls must allow traffic through the appropriate ports. Firewalls must permit VMs to contact quorum service computers using UDP port 4557.
