Overview
ETERNUS DX90 is an entry level disk storage system that is reliable and secure Data Safes. ETERNUS DX90 supports asynchronous and synchronous storage-based replication between two sites for business continuity. This model can be equipped with 12x 3.5” drives per 2U shelf. ETERNUS DX90 scales from 2 to 120 disk drives.
ETERNUS DX90 integrate well with multi-vendor infrastructures and backup solutions. Different drive types can be mixed and matched, secured by monitored RAID levels and features to ensure data integrity. Administrators can dynamically move data, spin drives down to save energy or encrypt data to prevent unauthorized access. In the event of power outages, the content of the cache is secured to flash memory. A backup copy is always at hand via snapshots and clones. The storage management software ETERNUS SF Express simplifies operation and maintenance.
Features
- Redundant RAID controllers, fans and power supplies that are hot swappable
- Cache Protector uses capacitor technology to better protect RAID controller cache during power outages
- Redundant Copy rebuilds a disk automatically as soon as the first signs of failure appear
- Data Block Guard appends check codes to every data block and verifies them at multiple checkpoints
- RAID Migration enables LUNs to be moved dynamically between different RAID groups and hard disks without interrupting operations
- Mixed SAS, Nearline SAS disk drives and SSD
- Eco-mode spins down disk drives
- Latest technologies and improved RAID Controller
- Fibre Channel host connection
- 15,000 rpm SAS, 7,200 rpm Nearline SAS disk drives and Solid State Drives (SSD)
- Storage based replication via 8 Gbit/s Fibre Channel and 8 snapshots (standard) upgradeable to 1,024
- Intuitive web interface
- Storage management software ETERNUS SF Express is bundled
- A wide range of Operating Systems, servers as well as applications are supported
