V2.0 of RozoFS Scale-Out NAS Software

Rozo Systems SAS announced that version 2.0 of its RozoFS scale-out NAS software has been released.

It delivers increased performance and data integrity and it introduces new functionalitythat improves the ease of use.

RozoFS is a true scale-out NAS that delivers performance on all data sizes, a requirement in many applications, including media and entertainment and HPC.

Its performance is associated with a disruptive erasure coding technology that works on files of all sizes.

New features of RozoFS version 2.0 include:

128-bit erasure coding: Boosts the encoding/decoding performance by leveraging the 128-bit instructions of the x86 processors. The result is throughput of 10GB/s on 4KB blocks.
Local auto-repair: Supports the auto-repair (‘self healing’) of one failed disk on the other disks of the same storage node, preserving the redundancy level for each file.
Quota per user and per group: Implements a familiar Linux-like quota feature. Enforcement can be configured on the fly and accounting is always on.
Multi-access modes: Supports three modes simultaneously: hierarchical access, the relative mode (parent/child) and the direct mode. The direct mode bypasses the metadata server for increased performance.
Data integrity and self-healing: Protects each block on disk with a CRC32-C checksum, eliminating all error sources between disk and application. In case of data corruption, RozoFS repairs the faulty block on the fly.
Geo-replication: Addresses the case where fewer than four sites are available. The geo-replication is always asynchronous with a configurable replication rate. By default it operates in Active/Standby mode, with Active/Active also supported.
Metadata optimization: Improves metadata operations by introducing time and space notions in the metadata structure. For example, RozoFS creates files at a rate of 38,000 files/s per export. RozoFS also comes with popular Linux tools such as ‘find’ that has been adapted to RozoFS’ metadata structures. It enables indexing rates that exceed one million i?nodes per second; higher rates can be achieved when time is given as input criteria.
Split of the data and metadata flows: Avoids slowdowns of metadata operations (SSD) under heavy data (HDD) R/W loads.
256K I/O support: Provides better performance for sequential access and limits the randomness at disk level.

“Over the last year, we have engaged with many customers resulting in a better understanding of the market requirements,” notes Pierre Evenou, CEO, Rozo. “The new RozoFS release improves on our market leading performance and incorporates new functionalities based on the feedback we received from customers. The focus is on making our software easier to deploy and on delivering key new functionality while maintaining our performance leadership in software-defined scale-out NAS.”
