System Requirements

Virtualization Platforms

• VMware vSphere: Version 6.0 ESX host or higher is required.
• Microsoft Hyper-V: Appliance deployment requires support for the VHDX format.

VMware vCenter Deployment

vCenter 7 and vCenter 8 are supported.

System Resources

• CPU: 4 vCPUs
• Memory: 16 GB RAM (Memory may need to be upgraded based on scalability requirements. Refer to the scalability table for more information.)
• Disk Space:
  • Operating System Partition: 30 GB
  • Additional Disk Space: 80 GB
  • Total Disk Size in VMware: 110 GB

Network Requirements

• Latency: The latency between the administration PC and the Eyeglass VM GUI must be less than 15 ms (measured by ping).

Authentication and User Management

• Active Directory (AD) Authentication: An AD authentication provider must be available in the system zone for Role-Based Access Control (RBAC) and SID-to-user resolution API requirements.

Browser Requirements

• Supported Browser: Google Chrome is required. The browser must support WebSockets.
• Unsupported Browsers: Internet Explorer is not supported.
• Cookie Settings: Third-party cookies must not be disabled, as they are required for authentication sessions and file downloads.

Ports Requirements

Port	Protocol	Source --> Destination	Description
DNS 53 UDP	DNS	Appliance --> DNS server OR Appliance --> GroupNet (DNS configured on all clusters)	Functional DNS is a requirement for multiple validations needed for failover and Failover Readiness
TLS 443	TCP TLS 1.2	Appliance --> Internet	DR Remote Monitoring or Phone Home remote log upload for support and health checks
NTP 123	UDP	Appliance --> NTP server in your environment	Time sync should use same NTP as the clusters. Always disable VMware host VM time sync option.
SMTP 25	TCP	Appliance --> Mail server in your environment	Email of alarms from Eyeglass to your mail server
HTTP 80	TCP	Appliance --> Open Suse Mirror Repositories	URL to allow security updates: Open Suse Download Security patches come directly from Open Suse and requires the appliance to have access to download the patches and apply on a weekly schedule.
HTTPS 8080	TCP TLS 1.2	Appliance --> Isilon/Powerscale OneFS cluster	REST API is authenticated using the service account created here. Authentication uses Isilon session authentication method.
SSH 22	AES	Appliance --> Isilon/Powerscale OneFS cluster	SSH access for some CLI commands
HTTPS 443	TCP TLS 1.2 AES - Unsigned certificate	Admin PC browser --> Appliance	Secures client to browser access
Target Port 80 --> Destination random TCP source port on the browser	Only used to redirect to 443, can be blocked if needed	Admin PC browser --> Appliance	If connection on IP address port 80 is made, an HTTP 301, 302 redirect is returned on port 80 to switch the browser to https and url https:/x.x.x.x/eyeglass. No services run on port 80 and this is only used to redirect to port 443 HTTPS.
HTTPS 2011 Websocket	TCP TLS 1.2 AES	Admin PC browser --> Appliance	Websocket for real-time appliance to browser updates (redirected to 2012)
TLS 2012 Websocket	TCP TLS 1.2 AES	Admin PC browser --> Appliance	Websocket for real-time appliance to browser updates (redirected to 2012)
SSH 22	TCP AES	Admin PC browser --> Appliance	Secure shell access
Proxy login SMB 2 (only) 445	TCP	Appliance --> Isilon/Powerscale OneFS	Used to authenticate to AD through Isilon/Powerscale OneFS using standard Microsoft SMB authentication request for Role based login proxy interface
Dual DNS Delegation	UDP	Appliance Port 53 UDP DNS --> Groupnet(x) DNS servers	New in 2.5.6 or later, requires Eyeglass to be able to access the Groupnet DNS servers to validate Dual DNS delegation is configured correctly. The OS DNS is not used since the DNS that must be configured correctly is used by Isilon/Powerscale OneFS itself.
Internet Control Message Protocol	ICMP	Appliance --> Isilon/Powerscale OneFS	If for any reason ICMP is disabled, or PMTUD is not supported, this causes OneFS to default the MTU to 536 bytes, which typically leads to performance degradation.

Scalability Limits

Eyeglass Scalability Limits and Appliance Memory Minimum Requirements

Scaling Limit Area	Tested Scaling Limits	Notes
Number of Managed Clusters (1 appliance)	Manages up to 22 clusters	Contact Support for RAM requirements
SyncIQ Policies Across All Clusters	Supports > 100 policies with 64 GB RAM Supports > 200 policies with 84 GB RAM
Access Zones	Handles > 10 zones with 32 GB RAM Handles > 30 zones with 64 GB RAM Handles > 50 zones with 84 GB RAM	Requires 32 GB to 84 GB of RAM
Failover Job Limitations	Supports 100 policies in a single failover	Requires 64 GB RAM
Total Object Count (shares + exports + quotas)	Handles < 5,000 objects with 16 GB RAM Handles 5,000 - 10,000 objects with 32 GB to 48 GB RAM Handles > 10,000 objects with 64 GB RAM Handles > 20,000 objects with 84 GB RAM
Clusters Added to the Appliance	Supports 4 clusters with 32 GB RAM Supports 4 - 8 clusters with 64 GB RAM Supports > 10 clusters with 84 GB RAM
Performance Auditor	Requires a minimum of 32 GB RAM when the Performance Auditor is licensed	Minimum 32 GB RAM
Concurrent Administrators (3 or more)	Adds 8 GB RAM to the above requirements for each logged-in administrator using RBAC or not using RBAC

info

Each release of the software may adjust memory requirements, and the alarm code (SCA0094) will recommend memory for the supported configuration. The recommendation from Alarm Code SCA0094 takes priority over this documentation.
