eterio MD Disk Arrays

eterio SAN MD offers high-availability storage solutions with a stable, reliable, and modular design, available in 2U-4U heights. These devices are easy to install and provide user-friendly management interfaces, making them ideal for all SAN environments and corporate applications (such as databases, virtualization, video editing, backup, and video monitoring). The entire product line is fast, flexible, and reliable, allowing the configuration of the perfect device for data storage and sharing according to required performance and budget. The devices provide a full spectrum of capabilities required by modern applications. With a wide range of configurations, host interfaces, drive types, expansion options, and various RAID levels, each eterio SAN MD solution is configured to meet the users’ storage requirements.

The eterio SAN MD series represents a new generation of high-performance and high-capacity SAN systems: simple, secure, scalable, and economical. Advanced features such as thin provisioning, SSD read/write cache memory, auto-tiering, snapshots, and replication are now also available to SMB users. The extensive range of eterio SAN MD solutions covers almost all SAN areas and customer requirements, from SMBs to corporate companies and institutions. These devices are used in critical data processing centers, virtualization, multimedia, or as large-scale video monitoring devices.

The solutions are available in three classes (S, M, L), differing primarily in performance (type of installed processors, cache memory size). A wide portfolio of solutions is available:
