Five good reasons to use IBM Spectrum NAS
Simplicity of deployment and administration
A wizard-based guide allows for setup or upgrade in 30 minutes. Identical software per node further simplifies setup and maintenance. IBM Spectrum NAS supports rolling upgrades over the network, fully transparent to the clients and without service interruptions. To deliver uninterrupted service, the system can take down one node at a time for upgrade, passing the node’s IP address temporarily to another node while the upgrade is done.
IBM Spectrum NAS reduces hardware needs and capital expenditure by working with industry-standard x86 servers deployed as high-performance scale-out storage clusters. The use of a symmetric architecture minimizes bottlenecks or hotspots as the cluster scales. With no single point of failure, customers can use inexpensive off-the-shelf hardware. IBM Spectrum NAS is hardware-agnostic and readily scalable, helping reduce the cost and worry of future data migrations and hardware replacements.
Capacity and performance scaling to meet growing demand
The IBM Spectrum NAS architecture is designed for scalability: adding more storage nodes provides a linear increase in average performance in the cluster. All the resources in the storage cluster are aggregated, including CPU, bandwidth, storage, and cache, giving a persistent high throughput for a high number of simultaneous users. Adding more nodes increases throughput and adding more cache reduces latency. The more nodes in the cluster, the less time it takes to complete tasks.
Native NFS and Microsoft SMB protocol support
You can run all your NAS-based applications with native support for NFS and SMB protocols with high specification compatibility. IBM Spectrum NAS offers a rich set of data management capabilities, including encryption, anti-virus, quota, tiering, snapshots, mirroring, transaction-based power-loss protection, and cluster self-healing.
The IBM Spectrum NAS architecture is symmetrical, with every node running the same small, efficient system core. This architecture, coupled with data redundancy, enhances reliability by avoiding any single point of failure. Erasure coding provides data redundancy and protection, with data being striped across nodes and locations. If there is a hardware failure, the cluster’s other nodes are notified, then work in parallel to recreate the missing data.
