Data Locality

NFS support

When it comes to remote files access and sharing, the number one option most system administrators choose is Network File System (NFS). NFS is a distributed file system protocol that allows users accessing remote files and data over a shared network just if they were stored locally. As to VM storage management, and VMware vSphere particularly, NFS is much more convenient comparing to FC and iSCSI. This all leads the NFS protocol to be effectively used for simplifying IT infrastructure scalability and ensuring centralized data management since it provides simple and convenient access for multiple systems. Nevertheless, considering the configuration of traditional HA NFS File Server, certain challenges may arise.

Problem

The number one problem companies usually face is high capital expenditure since the HA NFS implementation requires some form of shared storage. This leads to the need of deploying additional servers, non-redundant JBODs or even costly SANs. Another challenge is low return on investment (ROI) of the overall solution since more investments are required to improve the performance of the hardware already in use. Furthermore, the customer lifecycle value (CLV) gets crippled due to the lack of data services including caching, snapshots, QoS or data optimization features in the existing solutions. Therefore, building a unified and redundant platform with a necessary set of data services becomes a pitfall that is hard to overcome.

Traditional implementation of an HA NFS File Server

Solution

CAPEX and OPEX are significantly reduced since StarWind eliminates the need in dedicated shared storage. It unites the storage and compute layers virtualized on commodity servers, allowing the cluster footprint to go as low as 2 nodes.

The solution’s ROI also gets improved thanks to StarWind multi-level redundancy and high-performance architecture. Performance gets a considerable boost with DRAM and Flash caching functionality. The CPU overhead is minimized due to RDMA implemented for data synchronization.

CLV is increased as StarWind delivers such data services as caching, snapshots, QoS, and data optimization features. Furthermore, simple software updates throughout the solution’s lifecycle offer extended functionality providing additional value for companies.

‘Shared nothing’ approach to the implementation of an HA NFS File Server

Conclusion

StarWind solution significantly reduces companies’ CAPEX and OPEX and in turn, offers high performance and availability for mission-critical applications. StarWind guarantees higher ROI and CLV as it maximizes the power of an HA NFS File Server through efficient hardware utilization for shared access and provides beneficial data services.
