HYDRAstor is a family of systems used for long-term storage applications such as backup and archiving. The HS8-50S is capable of scaling to 165 nodes and 27.7PB of raw capacity. Inline compression and deduplication are included to increase the stated effective capacity to 353.2PB. The HS6-5000A is targeted at archiving and while it scales the same as the HS8, its overall performance is tailored for archiving. NEC does not state an effective capacity for the HS6 is the repository for the single original files. NEC also offers a Virtual Appliance version of HYDRAstor that customers can install on existing hardware infrastructure. It is targeted for the needs of remote offices, small to medium businesses, and virtualized platforms.
Access can be through a variety of remote file system interfaces. Object APIs (Amazon S3 and OpenStack Swift) are supported with the HS6 model. Remote replication is optional via IP to another HYDRAstor system with WAN acceleration and encryption of data in flight. Only deduped and compressed data are replicated.
Two types of nodes are supported in the HS8 and HS6 configurations, Hybrid Nodes and Storage Nodes. Both contain 12 HDDs. A Hybrid Node adds capacity, performance and additional network connections for host access. A Storage Node adds capacity only. Forward Error Correction using erasure coding is used for data protection with the capability to protect from up to six drive or node failures. HYDRAstor supports an ecosystem of backup, archiving and enterprise data management solutions and partners.
