Coraid ZX: High-Performance NAS


Coraid ZX is a family of file storage appliances that combines an innovative and feature-rich file system with scale-out, massively parallel Ethernet storage technology.


File Storage Built on Coraid EtherDrive

Unstructured data is growing at a faster rate than ever before within enterprises. Companies are grappling with the ballooning cost and complexity of managing block and file storage infrastructure at scale. Traditional NAS approaches to deploying storage for block- and file-based data do nothing to reduce the operational complexity of storage management.

Coraid ZX is a modern, feature-rich file storage appliance based on the Zettabyte File System (ZFS) and designed to work with Coraid EtherDrive block storage. An alternative to legacy NAS architectures, Coraid ZX is ideally suited for public and private cloud environments, video and big data applications, where rapid scalability, ease of use and flexibility are important in a file-based storage system.


  • Overview:
  • Features:

Coraid ZX leverages the open storage architecture capability of Coraid EtherDrive to bring together two best-of-breed systems – a high performance file system that can scale to a Zettabyte of storage and scale-out block storage infrastructure that offers simplicity and flexibility at a fraction of the cost of Fibre Channel storage.


Leveraging a shared pool of elastic block storage, the ZX-Series protects sensitive data and maximizes storage efficiency for public and private clouds at a fraction of the cost of legacy solutions. Administrators can easily deploy a pool of block storage within minutes, which can then be carved up and used by any number of front-end applications and file systems.


Scaling a ZX-based storage system is as simple as adding more EtherDrive SRX shelves for capacity. The use of Layer 2 Ethernet to connect storage shelves to Coraid ZX appliances obviates the need for complex, error-prone setup, configuration and multi-pathing.


By using the highly scalable Ethernet storage technology in conjunction with a best-in-class file storage / NAS offering, customers can deploy a unified storage solution that addresses a broad set of use cases and applications. By using the rich set of storage features that ZFS offers, such as remote replication, snapshots and clones, compression, and thin provisioning, enterprises can build highly efficient and flexible file storage systems.


File System Powered by Oracle Solaris ZFS with128-bit addressability
File-level Protocol
NFS v3 and v4; CIFS SMB v2
Storage Efficiency
Storage efficiency features include flexible provisioning with space guarantees, thin provisioning, user, group and filesystem quotas, and more
Hybrid Storage Pools
Optimized storage hierarchy with pools of storage containing DRAM, flash cache, and disk drives
Data Compression
Can select among 4 compression algorithms for tuning the right mix between application performance and storage
Striping, mirroring, triple-mirroring, single-parity RAID-Z1, double-parity RAID-Z2, triple-parity RAID-Z3, wide stripes
Remote Management
HTTPS / SSH / SNMP v1 and v2c with downloadable MIB, read-only / IPMI
Both Administrator and End-user accessible and manageable (security via RBAC), read-only mode
Writable snapshots created instantly via pointers without space or performance impact
Data Integrity
Protects against both ‘silent data corruption’ during disk storage, mis-copies, and mis-transmissions via checksums and other protections. Self-healing capabilities mean that the bad data is detected and automatically repaired using the correct data (for RAID configurations).
Directory Services
Network Services
NTP, DNS, DHCP, SMTP, and Kerberos
Local Replication
Supports replication within same ZX Storage Appliance configuration
Remote Replication
Supports replication from one EtherDrive ZX Storage Appliance product to another
High Availability
Integrated High Availability Active / Active with automatic failover and Active / Passive configurations
