Introduction

In the age of smart mobile devices, internet, mobile commerce, big data, and IoT, data emanates from a bewildering array of sources and applications—and it represents one of your business’ most missioncritical commodities.

Managing that flow of data (and storing that data so your company can protect it and put it to profitable use) presents 5 increasingly complex challenges.

Scalability: Data storage at the scale you need now and as your company grows
Capacity: Seamless and non-disruptive growth
Performance: Fast, reliable backup, storage, and retrieval
Cost: A competitive solution that delivers value and leverages your ongoing investment
Security and compliance: Safeguarding critical data and ensuring that you meet regulatory requirements

Since 2007, NEC has set the standard in backup and archival storage with its HYDRAstor® disk storage solutions. This report examines 5 dimensions of the storage challenge and how NEC addressed them in designing a long-term solution to meet the requirements of companies like yours.

Scalability

SOLUTION: As your company grows from small business to fully networked enterprise, your data storage requirements will evolve. You need to manage that growth without sacrificing performance in backups, replication, or recovery—and with high resiliency.

HYDRAstor has an extreme capacity for scale. Solutions range from a 1 TB Virtual Appliance to an appliance built specifically for SMBs to a grid-based, fully redundant solution scalable from 1 to 165 nodes without business disruption. Grid architecture allows the system to grow in step with your primary and secondary storage needs. Mix and match storage or performance nodes as your business needs it. And with global deduplication, data rolls out automatically, even to nodes from multiple generations of technology, enabling in-place refresh without requiring data migration.

Then, as you add capacity, an automated process recognizes new nodes and optimally distributes data and processing. Each node typically provides 960 TB storage capacity, with up to a 63 TB per-hour ingest rate. Your HYDRAstor solution can scale from small business to enterprise requirements without requiring forklift upgrades or a loss of service.

Capacity

SOLUTION: Many conventional storage solutions are single-service platforms for backup/recovery or archiving. Your business requirements demand both. With a solution that provides both, not only can you allocate storage capacity on the fly, but it can also help reduce costs and ease the burden on expensive primary file storage arrays.

HYDRAstor is a multi-role platform for data recovery and long-term storage. It reduces storage capacity consumption by up to 95% with inline global deduplication, enabling high performance and low storage costs. It also frees up primary storage space by serving as the archive target. This can extend the life of the primary array, reducing its workload and maximizing its performance.

HYDRAstor enhances performance by using application-aware deduplication, recognizing and accounting for data layouts, caching, and other characteristics of different applications. It can increase space reduction by more than 130% by optimizing deduplication without impact from the corresponding application metadata. HYDRAstor’s DynamicStor™ technology help in virtualization of all available storage resources into a common shared pool, automatically allocating storage capacity on the fly and balancing incoming data across all nodes within the grid.

Performance

SOLUTION: Effectively architected storage can scale not just capacity, but performance in sync with your business needs. Today’s grid architecture ensures high availability and no single point of failure.

This approach ensures protection across your entire system. With HYDRAstor, you get the industry’s fastest ingest speeds for backup and recovery. And faster speed means faster recovery, reducing the impact in the event of a disaster.

NEC’s unique Distributed Resilient Data™ (DRD) erasure-coding offers stronger data protection than traditional Redundant Array of Independent Disks (RAID), with less capacity or processing overhead. DRD can tolerate up to 6 concurrent disk or node failures while maintaining normal I/O. And when data is lost, HYDRAstor automatically rebuilds only what’s missing using available free capacity on remaining disks. This leads to a faster data rebuild than with traditional RAID. With WAN-optimized replication, the system transmits only unique compressed data chunks and newer reference metadata. This functionality significantly reduces the network bandwidth requirements, sharing information with a separate HYDRAstor system via asynchronous replication.
