London based IT consultancy ISN Solutions are pleased to congratulate one of our engineering team leaders, Nilesh Vaghela, on passing his Citrix Certified Administrator (CCA) exam today with a mark of 96%!

The high mark may be because Nilesh already has a great deal of practical experience in Citrix software solutions. He is valued by many of ISN’s clients as a consultant who can resolve IT issues and implement new IT solutions quickly, effectively and without fuss.

ISN has five other engineers who have gained the the CCA qualification, however Nilesh is the first to pass the newly released XenApp v5 exam.

Congratulations to Tom Clowes, ISN’s senior support consultant, for passing NetApp’s Accredited Storage Architect Professional exam with a score of 90%!

This followed an intensive course at #NetApp UK HQ in Stockley Park where Tom was able to brush up on his knowledge of storage technology in general as well as learn all there is to know about the range of SAN and NAS storage solutions offered by NetApp.

This covered training on FAS2020, FAS2050, FAS3000 series and all the way up to FAS6080 filers as well as the core Snapshot technology which translates to easy data backup, file and volume restore (in seconds, not hours)and storage replication technology that is unmatched by any other vendor.

If you would like to explore how NetApp storage solutions can help your business, please contact us on 020 7313 9900 to arrange a demonstration, or come along to one of our short Demo Cafe briefings.

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.

Congratulations to ISN engineers Alex Woolsey and Chris Territt who successfully completed the safety training necessary to work on offshore oil and gas facilities.

Both engineers underwent intensive combined OPITO approved training course covering:

• Basic Offshore Safety Induction & Emergency Training (BOSIET)
• Helicopter Underwater Escape Training (HUET)
• Escape System Training (Norwegian OLF standard)
• Emergency Breathing Systems (EBS)

Like other ISN engineers they are qualified to work offshore from the North Sea to the Tropics. ISN need to maintain readiness to work offshore at short notice to provide IT support and consultancy anywhere in the world for our oil & gas exploration and production customers.

This involves taking a snapshot image of a whole server (or desktop PC or laptop). If the server fails, the image can be used to recreate it the server on any hardware – doesn’t have to be identical – long as it has enough disk space and memory.

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.

ISN have recently been reassessed and reapproved for ISO9001:2008 quality management systems, standards and guidelines for the provision of information technology and telecommunications consultancy services.

The updated certification replaces our previous 9001:2000 accreditation and shows that the company has demonstrated its ability to consistently provide product that meets customer and regulatory requirements. ISO 9001:2008 also aims to enhance customer satisfaction through effective processes for continual improvement.

People often ask us for ways to share files with suppliers, partners and remote workers when those files are too big to be sent as email attachments. After testing a few different approaches we’ve found the easiest way to do it.

One solution has been to set up an FTP site but that can be cumbersome for non-IT people. If hosted on your internal network, it could swamp your internet connection, or even provide a way in for hackers.

Having evaluated various sharing websites, we have found what seems to be the perfect solution in a new service called ShareFile. You can even brand it to look like your web site.

It ticks all the boxes for what we needed:

• Data stored externally
• Secure and encrypted data storage and transfer
• Easy to use for anyone, specialist or not
• Easy to control access for different recipients
• Low cost

ShareFile offer a free trial on www.sharefile.com. If you want to try it out for 30 days without having to submit a credit card, please call me at ISN on 020 7313 9900.

Many business need to send out regular information to their clients and email is the easiest and cheapest way to do it. The wrong approach is to create an email message, attach a document and send it out to 1000 of your contacts. This could cripple your mail server for hours and maybe even get you blacklisted as a spammer.

Here are the two most important tips for creating your own mailshots: Read more »

Cloud computing is one of this year’s hot topics. In a nutshell, it means locating your computing resources somewhere else, usually in a data centre run by a hosting company.

Many businesses are hoping that cloud computing will be a panacea to solve all the problems that appear to come from their computer room and all those troublesome servers.

However, even if your servers are located at some third party hosting site and managed by people who don’t work for you, those pesky problems may still occur and the overall costs may be less than owning and running your own servers.

Consultants from McKinsey & Co have produced a report which shows that moving your computing to the cloud could be a costly mistake. The McKinsey study, entitled “Clearing the Air on Cloud Computing” claims that outsourcing a typical data centre to the cloud could even double costs!

The report goes on to say that businesses could do better by running their own servers and using virtualisation to run them more efficiently. This approach may indeed hold the key to greater cost savings.

We at ISN tend to agree. While neither cloud computing or virtualisation will cure all corporate IT headaches, there is a place for both and, used to fulfill definite objectives, both can provide cost savings and better performing IT for businesses.

For instance, certain tedious but crucial tasks, like spam and virus filtering can be transferred to “the cloud” in the form of Microsoft Exchange Hosted Services for an insignificant cost and can deliver quick returns in terms of increased productivity and better security.

Similarly, our LiveVault online backup solution is a cloud-based application, which creates backups off site every 15 minutes at far less cost than an in-house solution could.

The cloud is fine for utility jobs like these, but the same approach doesn’t work so well for business critical applications where tighter control, flexibility and integration with other systems are high priorities. Costs of owning hardware are low in reality since they can be depreciated over several years or even written off against tax. Most organisations are having to get leaner in the way they use IT and server virtualisation is a clear way of squeezing more value out of your data centre.
