NEC HYDRAstor is a family of systems used for long-term storage applications such as backup and archiving. The HS8-5000 is capable of scaling to 165 nodes and 11.88PB of raw capacity. Inline compression and deduplication are included to increase the stated effective capacity to 158.4PB. The HS6-5000A is targeted at archiving and while it scales the same as the HS8, it’s overall performance is tailored for archiving workloads. The HS3-510 is a set of single node models delivering the same enterprise capabilities for small to medium businesses. The newest version of HYDRAstor is a Virtual Appliance which customers can install on existing hardware infrastructure. It is targeted for the needs of remote offices and virtualized platforms.
File 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 configuration, Hybrid Nodes and Storage Nodes. Both types 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 device or node failures. The default is three.
