Data Centre Tiers Explained

In this post we explain the difference between a Tier 1, Tier 2, Tier 3, and Teir 4 Data Centre.

The Tier number (1 to 4) defines the resilence and uptime of the centre. Tier 4 data centres are considered the most robust and least prone to failures. Tier 4 is designed to host mission critical servers and computer systems, with fully redundant subsystems (cooling, power, network links, storage etc) and compartmentalized security zones controlled by biometric access controls methods.

Tier 1 = Non-redundant capacity components (single uplink and servers).

Tier 2 = Tier 1 + Redundant capacity components.

Tier 3 = Tier 1 + Tier 2 + Dual-powered equipments and multiple uplinks.

Tier 4 = Tier 1 + Tier 2 + Tier 3 + all components are fully fault-tolerant including uplinks, storage, chillers, HVAC systems, servers etc. Everything is dual-powered.

Data Center Availability According To Tiers

The levels also describes the availability of data from the hardware at a location as follows:

Tier 1: Guaranteeing 99.671% availability.

Tier 2: Guaranteeing 99.741% availability.

Tier 3: Guaranteeing 99.982% availability.

Tier 4: Guaranteeing 99.995% availability.

The Importance of a Customised Software Solution

The increasingly competitive tendering process for services means it is now more important than ever to utilise custom designed software that is developed for your specific needs. Often, the off the shelf software suites either don’t offer enough features, or it’s too difficult to mould your processes into the pre-defined functionality. It is for these very reasons that your organisation needs a software design team that offers custom software development options that cater to your needs and requirements.

This makes Caseworker Connect Online the perfect choice for your service.

What is customised software?

Custom software is software that is built specifically for a group of users or an organisation with specific needs. It is very different than the software packages you will find readily available. Custom software is personalised to a specific business or group’s needs and includes a wide range of personal preference based features. Caseworker Connect Online is a hybrid solution rather than entirely customised. These features could be designed around a specific function the software will be intended for, including but not limited to; service user profiles, case management (of different services with different recording requirements), staff,  volunteers, and so on.
As with typical software development, the custom software development process has several different stages before the final package can be introduced. Caseworker Connect Online provides a proven framework that underpins all case management systems, which is then customised with the recording and reporting needs of the specific organisation. These stages give the software developer the ability to locate any software issues that might make the software unusable for the client, and it can enable them to fine tune the software package making it even more usable.

Is Custom Developed Software More Expensive?

Is custom software development more expensive? Initially, yes, but the benefits from using a software package that is customised to your needs and the needs of your business far outweigh the initial expense. It is critical that software solutions stay aligned with the ever-changing requirements of the organisation. This is easy to achieve with Caseworker Connect Online. Aside from a higher return on your investment, custom developed software packages can provide your organisation with a solid foundation for wider systems integration and save you time in bringing new services or departments. Custom developed software is also easier to use immediately, and it can be upgraded and improved with less down time in the future.
