Tenant Managed Services (TMS)

Tenant Managed Services (TMS) is the Statewide Data Center’s colocation service offering.  TMS allows customers the ability to choose which features are needed to best meet specific departmental needs, while reducing statewide data center floor space and greenhouse emissions.

Two models of co-location service are offered:



TMS Basic (formerly known as COEMS) provides secure space in a state-operated, Tier III equivalent data center, while still allowing customers to maintain full control over their computing environment. Tenants also provide and manage their own security components (e.g. Firewall, IPS, etc).



TMS Premium (formerly known as FDC) offers an additional layer of service.  In addition to providing secure space, it also provides a managed local area network (LAN) and storage area network (SAN). The Managed LAN includes Firewall and IPS; tenants manage their security context.

The TMS Security Standard discusses the requirements that must be adhered to for both physical facility access and data protection. The Data Classification Standard should be followed to ensure that the State Administrative Manual (SAM) section 5305.5 and the Statewide Information Management Manual (SIMM) section 5305-A are adhered to.

The table below is intended to provide clarity around roles and responsibilities between CDT and Tenants for each TMS Model.

How do I contact the TMS Support Group to obtain additional information or to submit questions?

What is the difference between TMS Basic and Premium Model?

Both models are a type of co-location service, where customers host equipment at the CDT Data Center. The Premium model offers an additional layer of service.

In the TMS Basic environment, Customers have full control of their environment and must provide their own network connectivity and security (including routers, firewalls, Intrusion Protection System, etc.).

With the TMS Premium model, CDT manages the network and SAN Fabric that is shared amongst all customers within the TMS Premium environment. Customers utilize CDT owned and managed network equipment, which includes switches, firewalls, routers, and IPS. Customers are given a firewall security context in order to control all rule sets, logging, and authentication to their specific environment.

Are there hardware and cabinet standards?  

All Customers’ hardware must be assessed prior to installation to ensure suitability within TMS Basic and Premium areas. Considerations such as excessive power requirements, cooling needs, etc. will be reviewed during the assessment process. Hardware must be able to physically fit/mount into the CDT provided TMS Cabinets. Customers who request to bring in their own cabinets will be considered on a case by case basis.

After installation, CDT will provide a brief inspection to ensure that equipment is properly racked, cables are bundled, and power strips are plugged in redundantly. 

What assistance will CDT provide in moving equipment? Will TMS customer need to provide movers? 

CDT staff will coordinate access through the facility and loading dock. The customer is responsible for moving and installing/racking their equipment into their TMS Basic or Premium environment. The customer will have to physically move their equipment from CDT ‘s loading dock to the final destination within the TMS raised floor themselves or hire a move contractor. CDT does have limited moving equipment available to the customer with advanced notice. All packing materials, cardboard, Styrofoam, and pallets need to be removed by the customer. 

How to access TMS service areas? (Card key, Badge, 24/7, etc.) And who may authorize? 

TMS customers will have physical access to their cabinets 24×7. Each customer’s department authorizes who has access to their cabinets via a Tenant Contact List. CDT authorized staff will also have access based on emergency and maintenance needs.

Customers must submit a TMS Raised Floor Activity Request through the Remedy system at least 24 hours in advance to schedule their visit. If a customer is unable to submit a request within 24 hours advance notice, the customer must call the Service Desk at (916) 464-4311 and request that an Incident be opened for the visit. Additionally, visitors not listed on a department’s Tenant Contact List will require approval by a Department Authorizer prior to being granted access to the Computer Room.

Visits to the Vacaville site also require a request in the Remedy system. In addition, all TMS customers visiting the Vacaville site must be escorted by an CDT employee. Off-hour visits to the Vacaville site may incur additional fees to compensate for overtime costs.

Who is responsible for server software installation? 

The Customer is responsible for server software installation. 

Can customer deliveries be made to the Rancho Cordova Site? 

The customer is responsible for all deliveries made to CDT ‘s Rancho Cordova site and must be present (or a designee) to sign for and accept all shipments. Tight coordination between the shipper (UPS/FedEx or Private Company) and the customer is strongly encouraged. All delivery attempts made to the Rancho Cordova site without a representative on site will be refused and sent back with the shipper at the customer’s expense. Delivery notifications must be submitted via the CDT Remedy system. Equipment must be racked upon arrival.

CDT will not sign for or store customer-owned packages and assets. 

Will TMS Premium customers have their own set of IP Addresses? 

Customers can use an allocation of their own network IP addressing, use some allocation from the TMS Premium globally routable allocation, or get an allocation from CDT. Customers can use either globally routable or private IP addressing in their environment. TMS Premium was designed in such a way that there is no issue with Customers overlapping IP address space with other Customers. 

What appliances will/will not be acceptable to deploy within TMS Premium? 

Computing hardware is the ideal candidate for TMS Premium cabinets. All appliances must be rack mountable into the CDT provided server cabinets however all proposed devices will be reviewed on a case by case basis. 

What rights do TMS Premium customers have to their firewall in the virtual security context? 

Customers will have full manageability of their firewall security context. They will control all rule sets, logging, and authentication to their firewall security context. 

How many VLANs are allowed per TMS Premium server cabinet? 

Up to 10 VLANs per cabinet. 

Does CDT provide an NTP service in TMS Premium? 


How do customers connect to their TMS Basic environment? 

Option 1: Customers can order their own circuits via Calnet III, from their site to the CDT Data Center. CDT will extend the circuit from the MPOE to the TMS rack, for a one-time fee.

Option 2: Customers can request bandwidth (aka a ‘handoff’) to the Internet and other CDT resources to their TMS rack at the following speeds:

  • 56kb connectivity
  • T-1 connectivity
  • DS3 connectivity
  • 10 Mbps connectivity
  • 50 Mbps connectivity
  • 100 Mbps connectivity
  • 1 Gbps connectivity
  • 5 Gbps connectivity
  • 10 Gbps connectivity

Please note that each connection is associated with a both a one-time and monthly fee, per the CDT Rate Schedule. 

How do customers connect to their TMS Premium environment? 

TMS Premium includes redundant 10 Gigabit Ethernet connections to CDT ‘s CSGNET/iHub routers (aka backbone) as part of the service. All customers access TMS Premium through this connectivity. To get to the iHub, the customer must subscribe to CGEN or the Fiber Ring Service. These connections take customer traffic to the iHub, and then to the TMS Premium network. 

What are the advantages of 208 voltage power cords?

208 volt power cords draws less current than the standard 110 volt power cord.  Less current mean less heat; therefore, your device will run cooler and will help minimize the risk of equipment failure.  The lower power consumption will also help contributes to the overall power efficiency of the data center and will minimize power outage.
