This is the kind of IT work ISN does best

Check out the comms dome we put on the bridge of the Armada Perkasa FPSO for Afren in the YouTube movie below. A floating production, storage and offloading (FPSO) unit is a floating vessel used by the offshore industry for the processing and storage of oil and gas.

ISN were engaged by Afren to project manage and execute the voice and data communications parts of the project and delivered on time despite challenging deadlines.

This FPSO was fitted out for Afren’s Okoro Setu production project which achieved first oil in 2008 and still continues producing today, an average of 18,872 barrels per day in 2009.

Today several businesses and employees are waking up to a uncertain future in central London. On Friday a large scale fire broke out in Dean Street, Soho, gutting at least one business and leading to a large number of residents being evacuated for many hours.

Whether the fire could have been prevented remains unclear. Maybe the business involved has the ability to continue to trade; if not, they will have a number of difficult questions to answer about business continuity and disaster recovery.

If you have a disaster recovery plan, you hope never to use it. Putting one in place however, along with enabling technologies, would drastically reduce the downtime casued by an actual disaster, while improving the underlying infrastructure for day to day operations.

Impact analysis

ISN advise customers to regularly carry out business impact analysis of each business unit of their organisation. Understanding how a disaster would affect each business unit, in terms of hard and soft costs (lost orders and loss of future orders through brand degradation) is critical to developing a robust strategy to tackle any disaster. Getting your data to the right people quickly is a decisive point in allowing your business to continue.

Understanding that your data is not the only issue to deal with: new equipment, offices, and infrastructure may also be required. Implementing plans so that every member of your business understands how to continue with business as usual, in the event of a massive business outage is key.

Solutions

ISN recommends organisations look at technologies such as virtualisation, storage and offsite backups to help circumvent these situations. Mirrored storage would allow you to have you mission critical data to be centralised off your main site and allow for replication back to your head office when new equipment is installed. That, coupled with technologies such as Citrix XenApp to allow users to work from home as if they were in the office, means you lose fewer working days. If you are small enough not to need to shared storage, offsite back up can cut data restore times and get your business going again very quickly.

Next steps

ISN provides business impact analysis for organisation and provides disaster recovery planning services, in the form of a workshop. Our aim is to ensure that in the event of your business being involved in any disaster scenario, it quickly returns to business as usual instead of becoming business confusion.

ISN’s technical consultants have put their heads together and come up with some practical advice for IT teams considering introducing virtualisation.

1 – Start small and work up

So that you and your team can familiarise yourselves with the concepts and issues around virtualisation, start with free or inexpensive tools like #Citrix #XenServer, #VMware ESX3i or VMware Workstation.

Try For your first production systems try running simple server workloads like Blackberry Enterprise Server, DHCP or secondary domain controllers.

2 – Take a phased approach

Don’t try to do everything all at once. Trying to do too much in one step is a recipe for downtime and disaster. Specialist consultancies can provide the tools and expertise to help you plan the best way to get to your desired end results.

3 – Don’t expect to be able to virtualise all of your systems

Sometimes you are better off with physical servers. Direct attached storage in the form of RAID arrays on an intelligent caching disk controllers will often give better performance for high throughput databases than virtual machines accessing shared iSCSI storage.

4 – Check compatibility of existing software applications

Confirm with vendors that their applications are supported on virtual machines and consider their recommendations when looking at server, network and backup options.

5 – Don’t forget about licensing

Remember OEM licenses are tied to the hardware they were bought with, so that you can’t simply convert a machine running OEM software and stay compliant. Each virtual Windows server or desktop would need its own operating system license – either volume or retail box.

6 – Think about backup and recovery up front

Although it is easier to back up and restore, a production virtual machine needs a proper rigorous backup regime in place to allow quick recovery from data loss. Choose products which are designed for virtual systems such as those from Vizioncore or Symantec.

7 – Upgrade hardware warranty

When you are running multiple production virtual machines on one physical server system, this become vital as any downtime is compounded. For HP servers ISN recommend 24/7 6 hour Call-to-repair or 4 hour response Carepack warranty extensions. Dell too offer a “4 hour Mission Critical” response add-on to their basic warranty.

8 – Build a solid foundation for the future

Don’t try to skimp and put your first production virtual machines on a low-end system as this will generally become your production environment before you know it. Hardware is cheap compared to the cost, disruption and inconvenience of rebuilding. There is also a cost to eroding users’ confidence in new systems by providing it on under-powered hardware. Choose reliable, fast server hardware with redundancy built in.

9 – Use shared storage for more flexibility

For non critical server workloads with very little data it is feasible to keep the data within the virtual machine. To get the most out of a virtual environment, realising the full benefits of disaster recovery, resilience, flexibility and performance, it is best to separate critical production data and locate it on a shared Storage Area Network (SAN) or high end Network Attached Storage (NAS) device.

10 – Plan network capacity for best performance

ISN use iSCSI or fibre channel accelerators in servers attached to a separate storage LAN with a dedicated switch fabric to guarantee fastest data access times and throughput between servers, shared storage and users. If your server uses the same LAN for iSCSI access to a SAN as it does to serve data to users, problems can arise.

11 – Use outside expertise to give you a head start

It can save a lot of time and money to use an experienced consultancy to get you started on your virtualisation project. ISN’s qualified consultants can help you get results fast and transfer practical skills to your own IT team.

The annual conference for the EAGE – European Association of Geologists & Engineers – took place in Amsterdam last week – 8th to 11th June. A great opportunity for professionals in geophysics, petroleum exploration, geology, reservoir engineering, mining and civil engineering to get together for one of the key events of the oil and gas IT calendar.

As an IT infrastructure specialist for the Oil & Gas industry, London-based IT consultancy ISN Solutions partnered storage vendor Isilon Systems on their stand at the show. ISN have much experience of consultancy, design, project management, installation and support of IT and comms infrastructure for the oil & gas exploration and production sector.

With seismic data storage very much on the agenda and new applications for its manipulation and interpretation being showcased, ISN and Isilon where kept busy with interest on how best to manage the obvious storage implications, not just now, but allowing for likely growth patterns into the future.

Isilon’s scale-out NAS products offer unparalleled speed of access, uptime and cost effectiveness for storage of seismic data. Having evaluated the options available in the marketplace, we have been impressed by how easy  Isilon clustered NAS arrays are to manage and maintain. We have seen nothing that scales so well, while still maintaining extremely fast response times. Isilon’s product range includes solutions for storage needs from 5 Terabytes to over 5 Petabytes. Ideal for many geoscience applications.

Call us on 020 7313 9900  to tell us more about your storage challenges.

An ISN client made the tough decision to make a few staff redundant because of the downturn. They have a tight procedure for handling logon account deactivation and return of security badge, etc. However one of the departing staff asked if his account could be reactivated from 5pm for half an hour so that he could finish off a key piece of documentation. His boss agreed to let him finish the work.

Data wiped out

The next day some of his former work mates found that about 15GB of file data had gone missing – 4,500 files. When the IT support team investigated, they saw from the logs on their NetApp Storage Area Network (SAN) system that a folder which was backed up at 5pm was no longer there at 6pm. On closer inspection, they were able to establish that the missing folders had been deleted at 5:20pm.

Snapshot restore

Their NetApp SAN is set up to take snapshots of all data at hourly intervals, so restoring to the 5pm copy meant that all of the deleted data was able to be restored completely. In addition, it took a mere 10 minutes from noticing that the data was gone to having it all back to normal.

Tape backup?

If our client had relied purely on tape backup then it would certainly have taken a lot longer; many companies only take a tape backup of their data once a day. This would mean that they would have lost a day’s work and it might have taken hours to get the previous might’s version restored.

Investigate better backup methods

The cost of storage is falling and the amount of data held by businesses is growing (some say the it doubles every two years). It is nearly always cheaper to add more space than to prune the data set down to size. However that can create other problems if the backup solution is not scaled up to match.

There are plenty of gotchas in IT. To avoid them, please call our consultants to get some practical advice. We are trained and experienced in providing infrastructure solutions which help businesses be productive, even when the unexpected happens.
