Pure Storage's underlying strategy has been to use inline data deduplication and compression along with other technologies to bring the effective price of flash storage down to levels comparable with disk storage.
Part of the equation is that it is often necessary to over-provision disks to obtain the required performance, whereas the speed of flash means deduplication and compression can be applied immediately to squeeze a given quantity of data into around one-sixth as much storage. The exact saving varies among different types of data, but Pure believes 6:1 is a realistic average.
Pure's original product was the FA-420, which could accommodate between 11 and 35TB of flash for an effective capacity of up to 125TB. But for some customers that was too much, and for others it was not enough, so it has introduced the FA-405 and the FA-450.
Mr Cornwell explained that smaller companies have been approaching Pure asking for a product that meets their needs, and the FA-405 was created to meet those demands.
Although the new model was only publicly announced overnight, he said Australian companies were among the first to purchase it.
The FA-405 delivers up to 100,000 32K IOPS, compared with 150,000 from the FA-420.
Company officials suggested other applications include virtual desktop pilot projects and single database acceleration.

But just as some organisations needed a smaller storage array, others - especially larger enterprises - wanted a scaled-up version, hence the FA-450 (pictured below) which can be fitted with 34-70TB of flash for an effective capacity of up to 250TB. It is rated at up to 200,000 32K IOPS, and features 16Gbps Fibre Channel connectivity compared with the 8Gbps on the smaller models.
Both new models are available immediately - pricing is available from Pure's network of around 20 channel partners in Australia and New Zealand.
The FA-405 can be non-disruptively upgraded to an FA-420 or an FA-450, and a FA-420 to a FA-450. This is part of Pure's 'Forever Flash' model that eliminates the need for forklift upgrades for storage arrays.
Announced alongside the new models was version 4.0 of the company's Purity operating software.
New in Purity 4.0 is Pure's FlashRecover technology that provides data reduction aware replication and snapshot services for space-efficient point-in-time copies. It allows replication to occur every minute if required, and also supports rollback in the event that faulty data has been replicated,
Purity 4.0 also includes an enhanced version of FlashProtect to provide rapid data locking and dark site support services as well as the existing AES encryption and high availability.
Purity is included in the price of Pure's storage arrays, and existing owners can upgrade to version 4.0 at no extra charge, Mr Cornwell stressed.
