Storage array maker Avere has launched a tiered storage networked-attached storage (NAS) product that exists as a virtual appliance in the Amazon Web Services (AWS) cloud. The CloudFusion product provides file access storage and moves data to RAM, flash and SATA tiers according to frequency of access.
CloudFusion is purchased by customers from the AWS Marketplace and can accommodate up to 1.5TB of data, which is accessed via NFS (Linux) and CIFS (Windows) file access protocols.
The product runs as an Amazon Machine Image version of the Avere operating system (OS) file system in the Amazon cloud. The customer can configure RAM capacity on the Amazon Elastic Compute Cloud (EC2) flash storage in Amazon Elastic Block Store (EBS). They can also specify that less frequently accessed data can be tiered off to Amazon Simple Storage Service (S3) storage buckets, where it is held on SATA drives.
Avere claims it can provide the least costly cloud storage in the market via CloudFusion because of its ability to tier. Avere president and CEO Ron Bianchini said this is because it only holds hot data in EC2 RAM and EBS solid-state drives (SSDs), while bulk storage is held in cheap Amazon S3 storage.
“We use EC2 and EBS for high-performance data and S3 for capacity provision to give the lowest cost of any cloud NAS solution," he said. "NetApp's Cloud Ontap and Amazon's Elastic File System use only one storage media, so we're effectively offering capacity scaling at the S3 price of about $0.03 per month.”
CloudFusion is aimed at customers with relatively limited capacity needs – up to 1.5TB – and for file access.
Bianchini said this includes those looking for a single storage server – no more than one node is possible on Amazon Marketplace – in areas with large file requirements, such as media and entertainment and those with large numbers of files in analytics use cases, as well as web services workloads.
He claimed it could guarantee data requests would be served from high-performance cache in 98% of cases, with only 2% going out to S3 as long as the working dataset remained within 1.5TB.
For use cases with larger and more performance-hungry needs, Avere recommends its vFXT product that was released in 2014. This also runs on the Amazon infrastructure, but it is not bounded by Marketplace limitations and offers up to 50 nodes of 8TB each.
