Virtual Servers & StorageVirtual Servers

Server virtualization is a server hosting service where multiple servers can reside on a single physical host system.

Virtual Server SLA

Virtual Server Service Level Agreement

Print pdf version


This agreement is to define Virtual Server services provided to a Customer. Service definitions include hours, availability, support or duration and restrictions on support. This Service Agreement (hereafter Agreement) is effective between Information Technology Services (ITS) (hereafter referred to as Service Provider) and departments that have purchased this service (hereafter referred to as Customer) and establishes a commitment for providing virtual machines (hereafter Service) as detailed herein. This document clarifies both parties’ responsibilities and procedures to ensure Customer needs are met in a timely manner.

Services Provided

The following service(s) are provided to the Customer:

  • The Customer is provided a virtual server (VM) in a VMware ESX Server environment.
    1. Virtual Server(VM) service consists of;
      • One VCPU
      • 4GB ram, additional charges for every increment above base ram.
      • Operating system license ( Windows and Redhat Linux)
    2. Wware Server environment consists of;
      • ESX Server farm

        VM’s are hosted on a virtual server farm, providing high availability. If a physical server fails, we use Vmotion technology to seamlessly move the virtual machine to another physical server without service interruption

      • Dual network switches with automatic failover for SAN connectivity
      • Accessibility via remote console including system power control
      • Snapshots

        Service Provider will take snapshots which will be available for rollback. "Snapshot" service for virtual machines provides a copy of the operating system (OS) running on your virtual machine. The snapshot takes place while the virtual machine is running and does not require any type of reboot. A snapshot is invaluable in restoring the disk to a fully functional state to correct problems from a bad install or system error.

      • SAN data replication

        Service Provider will replicate data on SAN at WSEC data center to a SAN at East Campus.

      • Data Center hosted
        • Dual power feeds to servers and SAN UPS for long term power outages.
        • Climate controlled environment
        • Protected physical access 24/7
        • Basic monitoring of server functionality (e.g., server heartbeat)
      • The Service Provider will monitor the VM for the Customer and provide notifications on resource utilization.
      • Service Availability
      • The Service Provider will make the service available 24 hours per day every day of the year.

        Scheduled Maintenance; expecting necessary planned interruptions for service, upgrades, and reconfiguration. The Service Provider will minimize the number and duration of these interruptions. The Service Provider will attempt to coordinate with all affected customers to schedule the interruptions for times least disruptive to the customers. In general, scheduled maintenance should not affect customers with virtual servers having the ability to Vmotion.

        Planned Outages; The Service Provider will communicate planned outages to customers by email or by phone 3 business days before the outage. If a planned outage becomes necessary in cases of great urgency, the Service Provider will communicate soon after the outage necessity is determined.

        Unplanned Outages; The Service Provider will communicate unplanned outages as time permits, to the first available Customer contact by phone or, if unavailable, email.

  • Incident Management and Service Goals
  • The Service Provider’s staff will respond by email or telephone to the Customer’s incident within:
    • 4 hours for urgent issues 24X7 (see criteria below)
    • One business day; normal priority issue, service request, or business inquiry (see criteria below).
