Storage

The key to any modern efficient IT infrastructure is the storage platform, but delivering the right balance of capacity, performance, availability, features and price is always a challenge.

SNS can help you get it just right

On the face of it storage appears to be very simple, but the reality is that getting the right balance of performance, capacity, availability, features and affordability is a huge challenge.

It is very easy to get several of these dimensions right (i.e. cost and capacity), but this may well come at the expense of storage performance – the number one bottleneck for most virtualised environments.

Equally if you throw enough money at a storage platform it is very easy to address all of the requirements, except affordability.

SNS has the tools and experience to ensure that our solutions are optimally sized taking into account real world usage and likely growth – we then match these to the appropriate partner’s array model and the customer’s budget.

Performance

Performance

Flash in the Server and Array

Over the last 10 years hard drives have significantly increased in capacity, but performance has remained flat. At the same time there has been an approximate 100 times increase in the performance of CPUs, clearly for any application that relies heavily on disk IO storage performance has become a huge bottleneck.

The storage industry has responded by introducing Flash drive technology for arrays, these offer an order of magnitude increase in performance, but do come at the expense of a much higher cost per GB.

More recently there has been a move to placing Flash even closer to the application and installing it into servers, where it offers a further order of magnitude increase in performance when compared to storage array flash.

The challenge for IT departments is to work out where Flash will offer the best return on investment – maybe this will be in the server, in a hybrid array or even in an all Flash array.

De-duplication, Compression and Thin Provisioning

Relentless year on year data growth demands more cost-efficient storage, luckily modern storage arrays have the technology to fight back.

De-duplication can often save up to 70% of the used capacity, compression can be used with or with-out de-duplication to deliver further savings and Thin Provisioning prevents wastage – allocate what you like, but only use what is needed.

In addition tiering and caching technologies allow for the optimal use of drive technology to deliver the lowest cost per IO and per GB.

All of these technologies can be applied as appropriate to specific workloads – some times no efficiency technologies should be used and other times all will be used to provide the optimum configuration.

Automated Storage Tiering and Flash Caching

Each drive type has distinct advantages and disadvantages – Flash drives offer the lowest cost per IO, but the highest cost per GB and NL-SAS drives offer the lowest cost per GB, but the highest cost per IO.

Most environments consist of a small amount of “hot” data that is generating most of the IO, and a considerable amount of “cold” in-active data, the challenge is to find a way to place the data on the most appropriate drive type.

Storage tiering technology breaks the data into slices and then periodically moves the slices to make sure they are on the most appropriate tier.

Flash Cache technology places the “hottest” data onto Flash drives so that it can be accelerated to Flash speeds. The solution dynamically promotes and demotes data to ensure that the performance is delivered where it will have maximum impact.

Backup & DR

Backup and DR

Replicated snapshots combine Backup and Disaster Recovery

Storage arrays are typically the foundation for most organisation’s disaster recovery strategies – simply replicate the data across sites and in the event of disaster the data is ready and waiting at the recovery site. When combined with virtualisation not only is the data replicated, but also the virtual machines – now applications can be made available within minutes of a disaster being declared.

Snapshots offer an alternative to traditional backup solutions, with the advantage of near instant backup and restore. When combined with replication they provide a great way to automate the creation of off-site backups – typically negating the need for the frequent use of tape.

Layer on top application agents with full indexing across snaps and tape, and you have a data protection solution for the 21st century – able to scale to what ever capacities we are likely to see in the future.

Continuous Availability

Continuous Availability

Going beyond ‘five 9s’

Visualization has made most IT departments very familiar with clustering technologies (i.e. VMware vMotion, High Availability and Fault Tolerance) that have empowered them to absolutely minimise downtime within the data centre and provide continuous availability.

But what if there is a complete storage array or site outage?

Historically these clustering technologies were not available between sites, and instead active passive replication was deployed which required downtime and manual intervention to fail-over an infrastructure from one site to another.

Recently we have seen the introduction of technology that “stretches” storage between sites thereby extending the continuous availability capabilities across sites.

    VMware DR & Data Protection for Angel Trains

    There were just too many physical servers so we needed to virtualise as much as we could and make the process as painless as possible. In addition the business could no longer be confident that in the event of a disaster it could reliably recover, we needed the process to be streamlined so we can easily test our business continuity plan on a regular basis.

    VMware Data Protection for Jephson Housing Group

    We have a diverse infrastructure and therefore have deployed a wide range of backup products, we also tried a number of free or low-cost agent-less VMware solutions, but these proved to be unreliable. Backup had become a significant drain on the department’s resources and it had become clear that we needed to consolidate onto a single reliable solution.

    VMware Data Protection for University of Westminster

    The University has been running a mix of internal and out-sourced backup solutions for many years which has worked, but there has been a clear desire to reduce administration and consolidate these into a single solution. We were clear that any new solution would need to provide us with the ability to back up and restore our VMs without the need for in-guest agents to be installed.
