About 360is
Three Sixty is a specialist consultancy company focused on
technology infrastructure. We are experts in Virtualisation, Security,
and Performance Tuning.
We deliver high-risk, high-return, projects that transform our client’s
business critical systems. We are often called upon to rescue failing
projects or those where software and equipment suppliers have fled.
We are practitioners with a track record in hyper-growth, technology-
driven markets. Our founders introduced TCP/IP to the UK business
market, and were part of the team that built the UK’s largest ISP
(Unipalm-PIPEX) in the early 90s.
We work in the sole interest of our clients, and are free to
recommend the right technology or product for their project.

Scientists. Extremely bright, IT savvy people, with strong opinions of
what they want, running scientific applications, some of which are
very demanding of performance.
Some working environments have limited space for computers,
potentially inaccessible to IT staff for prolonged periods due to H&S
or clean-room requirements.
No shared storage at most of the sites.
Little data centre/comms room space at most of the sites.
High Availability is mandatory.

6GB RAM per VDI, 2 vCPUs minimum, Windows 7 64bit
Scientists run long-lived jobs that burn CPU for days
Relatively “write heavy” desktops, sometimes working with large files
Somewhat constrained for budget (end of year)

Dell & HP systems struggled to offer the required memory and CPU
density within the physical space, power, and cooling constraints.
IBM, Oracle, Bull, and Fujitsu were excluded on the basis of cost or
vendor lock-in.
Lack of enterprise shared storage would prove a challenge both in
terms of achieving high availability and sufficient performance to
satisfy end users.
3 classes of end user (regular, heavy, and power user) could be
easily serviced via a carefully chosen “gold image” and selective
publishing of specialty applications via XenApp.
This project was an “IT idea”, and had not been completely
socialised with the end-user community.

Dedicated Virtualisation Appliances were used in-place of
mainstream servers, high memory density, small physical size, low
power, in-built performance monitoring software.
Local storage was used in the appliances, hardware IOPS sink for
fast write access.
High availability without shared storage, achieved with a combination
of DNS and XenDesktop configuration, plus manual procedure for
fail-back once any faults were cleared.
4 physical systems, 2 sites, N+1 per site.
Lack of project socialisation with the end user community meant
several cycles of “snagging” would likely be required.

Performance was always going to be a focus with the end-user
community.
Using data from Virtual Estate Manager on the appliances, after 2
months of use (Dec/Jan) we conducted tuning work.
