Technology STORAGE MANAGEMENT
de-duplication and data compression and virtualisation brings efficiencies in management of data.
A commonly used solution for data access revolves around WAN acceleration technology but this is subject to limitations relating to bandwidth, file latency and already compressed data. The speed at which data travels across a WAN ultimately causes delays in data access that yield unacceptable productivity issues. Storage performance can only really be improved by interrogating configuration settings across all aspects of the WAN to optimise throughput on a continual basis.
Organisations with remote offices need their WAN links to transfer the data at near rated speeds, yet typically they greatly underutilized these expensive links. Configuring each server to work efficiently with the networking switches must take into account a wide variety of elements, including size of the link, transmit and receive buffers, type of traffic, protocols used, distance of users from source, and so on.
Installing a WAN acceleration device at either end of the link will improve the performance of certain types of traffic while bypassing other types. However, WAN acceleration devices come with a high capital cost and require their own specialized management. As well, these devices terminate the TCP session at either end, creating a ‘black hole’ of information.
Cloud storage, or storage as a service, is big business and brings it own set of challenges such as accessibility, replication and back-up over the WAN. Working your storage assets smarter utilises every last drop of available space reduces latency and keeps users satisfied.
You’ve been on an advanced driving course, you’ve sat at the wheel of your Ferrari Enzo, the tank is full with premium grade fuel, the track ahead of you is smooth and clear – but the fuel line is clogged. You won’t be enjoying optimum performance out of that supercar today.
You can compress data, de-duplicate data, reduce chatter, and speed up file transfer but only within the limitations of the settings between the OS, the servers, the applications and the client. You can have the fastest storage devices in the world but the effectiveness of any data access solution revolves around its ability to reduce delays. If your fastest, most reliable storage isn’t tuned to the OS to use maximum available throughput then your assets are underutilised.
Given the speed at which data is growing and the dynamic environments in which it moves, tuning the relationships between the OS, servers and applications needs to be a constantly iterative process and so Active Continuous Optimisation (ACO) is the only answer.
ACO addresses the root cause, not the symptoms – declining application performance is the symptom that usually causes reactive measures to be put in place. ACO dramatically
improves WAN throughput using existing servers and networks by automatically evaluating all aspects of the WAN link, then updating the servers’ configuration settings at either end to maximize throughput, much the same way that the Ferrari Enzo’s shifting program automatically selects shift timings to optimize speed.
WAN throughput can be improved up to 800%, and it does it using existing servers, networks and drivers, while your current management tools continue to provide full visibility into the network.
Veloxum – Active Continuous Optimisation As the first Active Continuous Optimization (ACO) infrastructure tuning solution for virtual and physical environments, Veloxum is transforming the process of optimizing complex infrastructure configuration settings and allowing enterprises to realize the full potential of their IT infrastructure.
eloxum actively and continuously optimizes physical and virtual infrastructure by optimizing operating system and application settings. It leverages the existing systems and infrastructure by tuning the various components within their manufacturer supported settings.
The solution enables IT organizations to maximize performance, increase workload density, and minimize virtualization and infrastructure costs, dramatically reducing CAPEX and OPEX spending.
