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.

Blue Door Software Announce TextStore for DVOnline

Blue Door Software announces the launch of TextStore for DVOnline – the premier online case management system for domestic abuse refuge and outreach services.

With TextStore, staff can:

  • Provide a secure mobile number to service users who can forward evidence of abusive or threatening messages. Messages are automatically logged to the service user’s case file
  • Forward text conversations to DVOnline that are then automatically assigned to the correct case file
  • Send text messages to their case files to record to-dos, reminders or prompts.

TextStore processes incoming messages and routes them to the correct case file. Copies of each message are stored in a secure database that can only be accessed by staff working with the service user.

“TextStore gives services the opportunity to integrate a critical method of support into their record keeping, namely text messages. We are always looking to develop new features that reflect the needs and demands of forward thinking domestic abuse outreach and refuge services and TextStore is another example of this. The rise of cyberstalking and the need to develop a reliable evidence base is another driver for organisations to use TextStore.”

Chris Hill, Product Manager. Blue Door Software


How much does it cost?

TextStore costs £99 to setup and then £20 per month. Organisations can send an unlimited number messages to TextStore.

When is it available?

We are looking for early adopters to start trialling the service in November with General Release from 1 January 2015.
