Software defined storage is developing alongside software defined networking and unified platforms, is another great leap on the horizon. What are the criteria for an organisation to decide on its next move in storage, leveraging existing assets as much as possible?
The software defined data centre aims to break down these application solution silos by abstracting the functionality of all the hardware components and pools compute, networking, and storage resources with the objective of automating these Data Centre functions.
This enables IT to react to new business and application requirements in a much more flexible and agile manner.
What VMware vSphere has done for the compute layer needs to follow for the network and storage layers respectively. Specifically from a storage perspective Business owners and IT departments alike do not want to see existing investments made redundant.
EMC ViPR software only solutions specifically addresses this concern while still enabling IT to respond and meet requirements effectively.
ViPR 2.0 has the ability to abstract separate heterogeneous storage systems including 3rd party and commodity, pool and automate provisioning policy tasks with its Control Layer. Once this is in place ViPR data services for Block, File, Object and HDFS can be requested for the Virtual Storage arrays regardless of whether the original system was capable of providing these services.
This way business get to utilise existing infrastructure while enabling System Administrators to manage multi-vendor storage solutions without the added complexity of need to be a specialist in these systems.
At Asystec we see other customers not weighed down with the problem of managing SAN or NAS Based storage solutions are increasingly looking at Internal DAS (Direct Attach Storage) Distributed Storage solutions whereby the design is aimed at removing the need for a central network based storage array solution.
VMware with VSAN and EMC with ScaleIO have developed software defined storage solutions that utilise internal disk devices on existing servers pooling the distributed storage across these servers aggregating storage performance and capacity without the need for centralised storage array.
This has enabled Asystec’s customers to ensure that underutilised local storage in existing servers can contribute to the overall shared storage environment.
