StorONE provides file, block and object storage on the same drives, supporting all drive types - NVMe, SAS, SATA SSDs and HDDs - in the same server. Pavilion Data provides block, file, and object access from its all-flash hardware, claiming it’s the most performant, dense, scalable, and flexible storage platform in the universe. Open source Ceph provides file, block and data access using an underlying object store. He said NexuStorage is a pre-revenue company and, once it starts earning revenue, then it may have permanent employees. And to be honest, over time, 90 per cent of Caringo’s work force was the same - they were all contractors.They had very few permanent employees.” I was never actually a permanent employee. The entire time at Caringo, he said, “I was … a contractor. This is the typical Silicon Valley startup business model, and it’s not unusual according to him. Development has been done by up to 50 external contractors.

It seems to us that the Nextassert technology will be crucial to the delivery of Nexfs’s performance and scalability. Olsen’s LinkedIn profile says he has filed a patent called “Addressing file data chunks over a REST interface without maintaining a file data chunk database, index or manifest.” We haven’t been able to find any more details than this.
#ED STORE OJECT STORAGE SOFTWARE#
He said: “This works because we don’t have a data location index and Nexfs can actually calculate where the data is.” Nexassert patent-pending software can (apparently) directly locate and access data belonging to a single file that resides on different storage classes without maintaining a separate index or manifest. Chunks from a file can reside on different tiers:

The object access method is S3.īecause the underlying file data is chunked, its access time is lower than that needed for a full file access. The actual storage hardware can be local drives on servers, a SAN, or on-premises object stores - for example, from MinIO, Cloudian and Scality, and AWS. If a single client changes part of the file, the changed chunks are unique to that client. SmartClone puts cloned copies of files on an object storage tier for protection or distribution. This means primary data is still available after a drive or system failure. SmartProtect automatically copies data in the hot tier to the cold object tier and also copies POSIX file metadata to the hot tier and to the object tier. Its migration of data between tiers can be triggered by file closure, a change in a file data chunk, and/or according to a set time schedule. This background process uses low and high tide so-called watermarks to decide if and when and how aggressively to move data between the tiers, with object storage regarded as the infinitely scalable back-end. NexfsĬhunks are placed on the hot, warm or cold tiers according to their access profile or personality and can be moved up or down a tier by a SmartTier function. The software runs on industry-standard servers and is available as a no-charge, downloadable Community Edition, with subscription-based, SLA-backed support coming soon. Nexfs delivers, he said, a unified, intelligent, cost-effective, massively scalable, data-lifecycle-enabled, storage system that can provide an up to 95 per cent reduction in primary storage capacity. The company is a nine-month-old founder-funded startup based in New Zealand, and briefed a virtual IT Press Tour on its technologyįounder Glen Olsen, an ex-product manager at DataCore-acquired Caringo, said his Nexfs technology removes the gap between the worlds of file and block storage on the one hand and object storage on the other, with the object storage either on-premises or in the public cloud. It has devised Nextassert software to do this without traditional data mapping indices, relational or NoSQL databases, manifests, stub files or symlinks. NexuStorage’s Nexfs software serves block and file data from an object-backing store using sub-file chunking to reduce data movement and help data tiering, and claims great tier-one storage cost savings and good performance.
