Pillar Data Systems continues storage efficiency drive
~increases array capacity and unrivaled disk utilisation rates ~

As part of the company's initiative to drive the highest levels of storage efficiency, Pillar Data Systems today announces the availability of 1TB SATA drives for its Pillar Axiom storage system. The new drives push the Axiom's overall usable capacity to 760TB.

Additionally,Pillar recently completed an extensive survey from its base of more than 250 customers and found that on average, Pillar Axiom users see an industry leading 62 per cent written disk utilisation. One-third of those customers are using more than 80 per cent of their disk array resources. No other open systems storage array on the market today can deliver those levels of disk use with minimal to no performance degradation.

'What separates Pillar even further is that these figures are written utilisation, not allocated, as is customary by all other vendors,' said Arun Taneja, founder and consulting analyst, The Taneja Group. 'These are clearly industry leading utilisation rates and support Pillar's position that its Axiom storage system is one of the most efficient disk systems on the market today. By driving usage rates so high without suffering performance losses, Pillar customers are deriving maximum value and efficiency out of their storage investments.'

Many companies have taken a disaggregated approach to ensuring application availability. The situation is largely a consequence of widely varying data types, usage patterns, SLA's and purchasing practices. Often, this approach results in islands of storage held captive by individual applications.

This issue is magnified by the fact that most enterprises have purchased incompatible point products with a variety of attach protocols, resulting in an environment where most storage capacity is grossly under-utilised. The associated management inefficiencies only compound this problem.

'Traditional storage technologies force users into a tradeoff scenario between capacity and performance,' said Chris Jones, vice president of sales emea, Pillar Data Systems. 'With the Pillar Axiom system's modular architecture, users can efficiently and non-disruptively scale capacity to meet the demands of the business, while maintaining performance, reliability and cost service levels.'

Pillar's ability to consolidate multiple data management cost centres to a single value centre is what makes the Axiom unique. Associated costs drop and utilisation rates increase when multiple applications and tiers of storage are consolidated into one single platform - all while maintaining the most effective quality of service for each.

The Pillar Axiom's ability to consolidate multiple storage functions into a single array has proven to drastically increase storage utilisation, but at a much lower level of capital spending.
