Nimble Storage cracks 'six nines' availability

By

Nimble Storage says its Predictive Flash Platform is achieving better than six-nines (99.999928%) actual availability.

The figure 99.999928% equates to less than 25 seconds downtime a year, so that's good news for Nimble customers. On reflection, it probably isn't news as they would already have noticed the high levels of uptime.

This figure is based on more than 315 million hours of collective uptime. More than 97% of Nimble arrays are running with zero downtime, according to the company.

This remarkable level of reliability is largely achieved thanks to Nimble's InfoSight system that collects a wide range of performance-related data and then applies a variety of data science techniques to recommend corrective action before potential problems become real.

More than 92% of support cases are automatically opened before administrators are even aware of the issue, and more than 86% of support cases are automatically resolved by InfoSight – even though more than half are not directly related to storage.

In February 2016 the company said it was recording 99.9997% availability.

"Flash-optimised arrays are quickly becoming the mainstream enterprise storage deployment model for mixed workloads, and customers are depending on these systems to consistently meet mission-critical requirements," said IDC storage research director Eric Burgener.

"Nimble Storage has demonstrated 'six-nines plus' availability, as it is based on actual measured, rather than projected, uptime across their entire installed base, giving their customers the confidence to deploy these solutions for even the most demanding applications."

Nimble vice-president of analytics and customer support (and the person who wrote much of the original InfoSight code) Rod Bagg said "Uptime is instrumental to business success – if systems go down, one can expect productivity losses and unhappy customers, all of which negatively affects revenue.

"We've found as we apply deep data analytics and machine learning across a growing number of arrays, collective availability also increases.

"Nimble arrays get smarter over time and our customers are reaping the benefits, with six-nines availability now a reality. Five-nines may be considered the gold standard of system uptime, but we are redefining what 'gold' truly means."

Active Vs. Passive DWDM Solutions

An active approach to your growing optical transport network & connectivity needs.

Building dark fibre network infrastructure using WDM technology used to be considered a complex challenge that only carriers have the means to implement.

This has led many enterprises to build passive networks, which are inferior in quality and ultimately limit their future growth.

Why are passive solutions considered inferior? And what makes active solutions great?

Read more about these two solutions, and how PacketLight fits into all this.
