We use only Dell servers in our web hosting
platform. Utilising state-of-the-art technology
we have built a web hosting platform that is
second to none
Our platform is designed in such a way that
if any server fails another server automatically
and without delay takes over that server's
workload. For example, if one of our mail
servers breaks down another server automatically
comes online, with all the correct
configuration, and takes over the work of the
failed server. During this period no email is
lost.
As well as this, all data is stored in two
large network disk arrays. Data is automatically
synchronised between the arrays so that in the
event of an array failing the remaining array
continues to serve data to the servers with no
downtime.
Web Hosting
Infrastructure
The following diagram represents the
Pctank.co.uk web hosting infrastructure.
Server Specification
Our current server specification is:
- Dual Quad Core Intel® Xeon® 3.16GHz with
2X6MB Cache
- 8 GB RAM
- Dual 136 GB SCSI Drive (for the
operating system)
- RAID Mirroring (for the operating
system)
- Dual Power Supplies
- Dual Gigabit Network Adapters
100% Cisco Gigabit Network
Pctank.co.uk's network operates on
industry-leading network equipment from Cisco
Systems. All our switches and routers are
developed by Cisco. Our network is based on
gigabit technology, which means that it runs at
a speed of 1000 Mb per second - most web hosting
networks are limited to 100 Mb per second.
Our network also utilises 100% CAT6 network
cable, which contains four pairs of copper wire
and, unlike CAT5, utilises all four pairs. CAT6
supports Gigabit (1000 Mbps) Ethernet and
supports communications at more than twice the
speed of CAT5e, which is the other popular
standard for Gigabit Ethernet cabling.
Redhat
Enterprise Linux Platform
Redhat is the leading provider of Linux open
source software. For many years now Redhat Linux
has been the number one choice for web hosting
companies, not just because of Redhat's amazing
scalability but also because of its track record
as the most stable operating system available in
the market today.
Our systems utilise the latest Redhat server
technology to allow our servers to be
continually up to date with Redhat system &
security patches.
Unlike many of our competitors we run Redhat
Enterprise Linux, the most stable release of
Redhat Linux available and the only version that
keeps completely up to date with security
patches.
Connectivity
Pctank.co.uk operates a multi-homed network
utilising BGP4 technology. Simply put, we have
multiple connections to the Internet with
different backbone providers, should any
connection fail our other connections
automatically take all the traffic. Not only
does this mean that we are very unlikely to lose
connectivity to the Internet, but it also means
that traffic moving to and from our network can
choose from a range of paths to get to its final
destination. This means that we have been able
to configure the network always to take the
fastest paths.
