Scalability and Backup Recovery found to be Key in Virtualisation Adoption, reveals Survey

So why the hesitancy?

London — A survey conducted by Symantec on 3,700 information technology managers in 35 countries, entitled “Virtualization and Evolution to the Cloud” revealed key points in what benefits businesses expect from implementing a virtual strategy. While there were many findings, some specific findings also showed two-thirds of enterprises list performance degradation as a somewhat/extremely large factor in their hesitation to place business-critical applications into a private cloud.

An excerpt from the Symantec whitepaper stated performance can be a factor that either drives virtualization or inhibits it. While virtualization/cloud computing can help streamline operations and save money, sacrificing performance is not an option. Any gains in other areas will be negated if customers and employees are unable to work within a fast, secure environment that provides maximum uptime. Among organizations that have implemented storage virtualization, 84 percent of respondents stated that one of their goals in doing so was to improve storage performance or speed. In contrast, two-thirds of enterprises list performance degradation as a somewhat/extremely large factor in their hesitation to place business-critical applications into a private cloud.

One key question in the survey asked how important the following goals were at the time of implementing server virtualisation and showed the following:

• 88% said somewhat/completely important to improve the scalability of our servers
• 87% said somewhat/completely important to reduce expenses
• 85% said somewhat/completely important to improve up-time and availability
• 83% said somewhat/completely important to improve recovery readiness
• 83% said somewhat/completely important to improve server speed

This hesitancy to fully implement a virtual environment is very much highlighted in another survey which was published in a whitepaper sponsored by EMC and carried out in conjunction with Computing.

• 5% have virtualised 96-100% of their IT infrastructure
• 17% have virtualised 70-95% of their IT infrastructure
• 16% have virtualised 50-69% of their IT infrastructure
• 21% have virtualised 30-49% of their IT infrastructure
• 16% have virtualised 10-29% of their IT infrastructure
• 10% have virtualised 10% of their IT infrastructure
• 15% have virtualised none of their IT infrastructure

The above statistics show that companies are only gradually going to a virtual environment, and by doing so hope to reduce expenses, improve scalability, improve performance and increase disaster recovery preparedness.

Technical Presales Consultant at Diskeeper Corporation Europe, Mandeep Birdi comments “From these statistics we know virtualisation to some degree is now very much a part of many organisations, but whilst implementing server virtualization, IT management need to also consider ways to ensure optimal performance in their virtual infrastructure. A major problem inherent in virtual infrastructures is that windows based virtual machines can generate excess I/Os as a result of fragmentation This unfortunately results in large performance drops on the host through these unnecessary I/Os and this can impact the success of the migrations. Our software solution, V-locity® virtual platform disk optimiser was specifically developed to address this issue.”

Scalability and Backup Recovery found to be Key in Virtualisation Adoption, reveals Survey

Diskeeper Corporation: Disaster Recovery Drives Virtualization Strategy

But many IT personnel are not aware of the hidden costs

Fragmentation in a
virtual environment

London — A survey conducted last year by Techtarget showed 33% percent planned to use a virtualization strategy to take advantage of the disaster recovery and high availability benefits. 23% also viewed virtualization’s benefits as a backup and data protection solution. A separate survey this year conducted by Coleman Parkes and commissioned by CA Technologies showed downtime costs businesses more than 127 million person-hours per year.

“Ensuring uptime is at the top of every IT administrators list. With virtualization you can automatically move virtual machines from one host to another and even from one data centre to another – so they’ll stay up and running, with little or no downtime, in case of a failure,” says Mandeep Birdi, Senior Presales Consultant at Diskeeper Corporation Europe.

However, more that 30% of both VMware and Microsoft virtualization users identified backing up VM data as a challenge, and also indentified storage management, I/O bottlenecks and server availability monitoring as major virtualization challenges.
Another survey conducted by Diskeeper Corporation Europe of 500 IT personnel showed 80% were aware of the major problems of I/O bottlenecks.

Mandeep Birdi comments, “Effectively shared resources are of critical importance in a virtual environment, but are severely impacted by three key barriers: I/O bandwidth bottlenecks due to accelerated fragmentation on virtual platforms, virtual machines competing for shared I/O resources and not effectively prioritized across the platform and thirdly, virtual disks set to dynamically grow do not resize when data is deleted – an issue known as bloating. Instead free space is simply just wasted. These problems can result in actually costing the company unnecessary spend on additional hardware as well as time in dealing with the issues”.

The survey also highlighted that 25% of respondents are not dealing with the problems of I/O bottlenecks, while 5% said they just purchase more disks/spindles.
Adding to this, Mandeep Birdi also reported that many IT users who are migrating to or have migrated over to a virtual environment, and have typically employed a SAN, are being told they don’t need to defragment the SAN, and that there isn’t an I/O bottleneck issue. He comments “This is false, the I/O bottleneck issue can have a huge effect on performance, and if the customer is not aware that this is what’s occurring in the SAN environment, it can again end up costing the company a lot of money with thinking they have to purchase more hardware, when in fact this might not be the case at all.”
