Q: Why do you need to lease an IDC?

A: IDC lease can greatly reduce costs, reduce construction period, and make you enjoy the highest quality bandwidth and professional information security services as follows:

• ◆ Electromechanical equipment used for data center construction is not needed;
• ◆ There is no need to train technical personnel required for data center and hardware maintenance;
• ◆ There is no need to invest a lot of money at the beginning;
• ◆ Single windows for planning, consulting, and obstruction handling are provided to solve customer problems;
• ◆ You can focus on your industry and do not need to worry about the monitoring management of electromechanical equipment and data centers;
• ◆ You can choose the information security protection products needed and do not need to learn how to set up information security equipment and interpret statements;
• ◆ HiNet backbone and HiLink VPN nodes are connected to provide the best network environment for the country.

Q: Why did you choose to lease instead of building a data center?

A：

	Enterprises’ self-built data centers	CHT IDC
Cost-effectiveness	Professional data center planning ability is required. A lot of equipment and capital are invested at a time, and the risk is high. It is difficult to consider expansion flexibility, timeliness, and cost-effectiveness. The spare is expensive due to the remote backup data center.	A lease provides items and dedicated IDC services. Services can be provided immediately, and the demands are adjusted flexibly. Multiple data centers are available and can be used as backups.
Security risk	Seismic, electric power, air conditioning, and fire protection facilities, as well as professionals, are required. Backup mechanisms shall be built to avoid network interruption in case of emergencies, such as typhoons, fires, earthquakes, or epidemics (e.g., SARS). Dedicated buildings are selected for IDC data centers to prevent complex building uses and in and out people from affecting security. Information security expertise is required to prevent persistent threats.	The data center is equipped with four-layer power backup and two sets of double-cold-source air conditioning, with a 99.995% availability. The seismic and fire-resistant professional data center structure and multiple access control are equipped to ensure security. Various information security protection, monitoring, management mechanisms, and professional SOCs are provided.
Network bandwidth	High-quality and high-bandwidth circuits shall be leased additionally to access the Internet. The bandwidth cannot be adjusted flexibly in case of excess. Circuit interruptions will stop network communications.	It can be directly connected to the HiNet backbone interface, with a 99.995% network availability. The bandwidth usage can be flexibly adjusted based on demand. Multiple network interface routes are provided, and information security threats are effectively reduced to increase bandwidth efficiency.
Maintenance management	Professional and shifting maintenance personnel are required to maintain the normal operation of complex mechanical/electrical facilities, equipment, and network. The foundation shall be maintained and replaced regularly to prevent service interruption.	Special windows for planning, construction, consulting, and obstruction handling, as well as a team for project data center maintenance, are provided separately to ensure 24*7*365 normal maintenance of the data center. Professional backup and spare maintenance facilities are provided.

Q: CHT has hihosting, hicloud, and IDC services. How to determine which product to use?

A: IDC lease can greatly reduce costs, reduce construction period, and make you enjoy the highest quality bandwidth and professional information security services:

• ◆ IDC services are recommended if your company has sufficient IT capabilities and designs the overall system and network architecture with a high degree of customization and high requirements on information security and hardware resources.
• ◆ If your company is small, needs to build a website or mail server, has basic IT capabilities, has certain requirements on information security, and does not have high requirements on website performance, hicloud cloud products are recommended.
• ◆ If your company is small, has no IT capabilities, needs to build an official website, and has low requirements on information security, a hihosting service is recommended.

Q: What if there are incoming lines of other fixed networks?

A: Now, in CHT-IDC, only Banqiao IDC can accept incoming lines of other fixed networks. If there are special requirements for other data centers (if any financial customer must have incoming lines of more than two fixed networks according to laws and regulations), the project will be negotiated separately.

Q: How to estimate the number of cabinets needed?

A: An equipment list shall be provided if you have no idea of the equipment’s power consumption and the number of cabinets. CHT’s technical units offer consulting services to assist you in estimating the approximate consumption. However, it must be noted that this is an estimated consumption, and the actual consumption will increase or decrease due to the use of the equipment.

Q: Which CHT-IDC data center supports the IPV6 network? How much it costs to switch to or share IPV6?

A: The CHT-IDC data centers in the region already support IPV4 / IPV6 Dual Stack and can deploy V6 IP to customers’ network devices. If there are any technical or architectural problems, the data centers can be asked for advice.
Most network devices in the market, including routers, exchanges, firewalls, and server load balancing (SLB), already support IPV4 / IPV6 Dual Stack. Devices, such as firewalls and server load balancing (SLB), can switch between V6 IP and V4 IP. After the switching between V6 IP and V4 IP by the above network devices, there is no need to change the back-end server, database, and software and cultivate technical personnel to maintain data centers and hardware.
