Virtual Server Hosting

1. General Overview

InCHIP Advanced Storage Solutions (InCHIP IT) provides Server Hosting Services. This Service Level Agreement is specific to the Virtual Server Hosting Services. Unlike “colocation” or other physical server hosting services, virtual server hosting is a service where a virtual server is leased and the customer is not required to make an initial investment in buying server and storage hardware.

This is a Service Level Agreement (SLA) between Virtual Server Hosting (VI) customers and InCHIP Advanced Storage Solutions (InCHIP IT). The scope of this document includes:

  • Services provided by InCHIP IT to Virtual Server Hosting customers.
  • Levels of response time, availability and support associated with these services.
  • Responsibilities of the InCHIP IT service provider and the customer.
  • Processes for requesting services and getting help.

2. Service Description

2.1 Service Scope

Technologies supporting virtual servers (guests) include physical server compute and memory resource on a server cluster and virtual server operating system disk space on redundant SAN infrastructure. The Virtual Server Hosting platform resides in the InCHIP IT server room. Included in the VI serves are the provisioning of the new server, operational support, consultation on sizing and appropriate use, performance monitoring, network firewalls and redundant network connectivity. Optional services include: systems administration of the hosted VM, backups and load balancing.

2.2 InCHIP IT Server Room

Our server room provides a safe and secure location for servers. This includes the basic infrastructure of cabinets, cables and uninterrupted power supply (UPS). In addition to this, our server room has N+1 redundant HVAC to provide year round cooling to protect equipment from environmental hazards of dust, temperature and humidity. Physical security includes door locks, ID cards, and alarms. Fire suppression equipment will help protect critical equipment from damage. In the event of a campus or Data Center power outage a natural gas generator will provide ongoing power. Enhanced cabinet power distribution provides redundant circuits and there is remote monitoring of the power distribution.

2.3 Operational Support

Operations provides 24×7 support for the server environment. There may be occasional graveyard shifts that do not have someone present, but in these circumstances there is a hotline to reach someone who can dispatch on call personnel. Operations support provides for environmental monitoring, physical security, HVAC and electrical (including UPS and generator) support and coordination with Physical Plant, and can provide hardware and network provisioning technician.

2.4 Hypervisor Support

Support of the virtual platform is provided by in-house senior engineering support personnel in regards to resource monitoring, VM guest provisioning and access assistance, identification of performance bottlenecks, coordination/communication of platform related items, virtual platform architecture and security compliance of the Virtual Server hosting platform.

2.5 Optional: Systems Administration (Managed Services)

Systems Administrators within InCHIP IT complete the installation and setup of the virtual server. “Managed Services” includes all services performed by a staff of senior level server administrators who are responsible for operating-system installation, patching and upgrades, operating-system troubleshooting, performance tuning, hardware management for physical servers; account management; and security administration. In addition, these administrators serve as a single point of contact on behalf of the client, interfacing with other InCHIP IT units including Information Security,  and Server Room Operations.
