Weka has developed a software-defined storage architecture that offers complete hardware independence while delivering an extremely performant solution that offers the flexibility of multiple protocol support. The design philosophy behind the Weka file system (WekaFS) was to create a single storage architecture, that runs on industry standard servers or on instances in the public cloud, with the performance of all-flash arrays, the simplicity and feature set of network-attached storage (NAS), and the scalability and economics of the cloud. At the heart of the design is WekaFS, a fully distributed, parallel file system that was written entirely from scratch to deliver the highest-performance file and object services leveraging NVMe flash as its primary storage tier between the application and the storage. Internally, and transparent to the application layer, the software seamlessly expands the namespace to a hard disk drive (HDD) layer built on any S3 compliant object storage system.

Component Software

Item NoComponentTypeName and VersionDescription
1WekaFSFile SystemVersion 3.8.3WekaFS is a parallel and distributed POSIX compliant file system that scales across NVMe enabled compute nodes, creating a single storage cluster that delivers high performance access to data. Each node in the cluster contains equal amount of data and metadata for optimal parallel file access and performance.

Service SLA Notes

AWS uses commercially reasonable efforts to make the Included Products and Services each available with a Monthly Uptime Percentage of at least 99.99%, in each case during any monthly billing cycle. (Monthly Uptime Percentage) is calculated by subtracting from 100% the percentage of minutes during the month in which any of the Included Products and Services, as applicable, was in the state of "Region Unavailable".

Memory Notes


Stable Storage

WekaFS uses the EC2 instances which provide stable storage. The data is journeled as well as UPS protected across multiple layers of the AWS infrastructure.

Solution Under Test Configuration Notes

The solution under test was a standard WekaFS enabled cluster in dedicated server mode. The solution will handle both large file I/O as well as small file random I/O and metadata intensive applications. No specialized tuning is required for different or mixed use workloads. None of the components used to perform the test were patched with Spectre or Meltdown patches
