High Performance 12Gb SAS DAS Storage Solution – CEI-816S / CEI-816SD


The CAEN Eng Model CEI-816S Direct Attached Storage (DAS) array features 12Gb SAS host performance to increase system efficiency and performance. It supports optional dual controllers and is equipped with 16 hot swappable SAS2/SATA3 hard disk drive bays with fast SAS2 host channels for a rapid, uninterrupted access to your most demanding applications requiring either high bandwidth or very rapid random I/O performance.

Engineered to meet stringent demands for continuous availability, CAEN Eng CEI-816S DAS array features a brand-new 1.2GHz Dual Core RAID-On-Chip processorGeneration3 PCI-E internal busDDR3 cache, parity-assist ASIC, completely cable-less back-plane based design, and storage capacities of almost 160TB in one small 3U disk enclosure. Further expansion is possible via SAS CEI-816J JBOD expansion chassis.

Low service and integration costs are assured by the CAEN Eng cable-less design, two redundant hot-swappable power supplies with two independent power inputs, turbo cooling fans, and embedded RAID controller. Three year warranty comes standard with every Direct Attached Storage (DAS) array and covers all components.

Features & Highlights

  • DataBolt™ Bandwidth Optimizer for balancing faster host & slower SAS or SATA devices
  • Supports SSD automatic monitor clone (AMC) to extend SSD lifetime
  • Supports Self-Encryption Drive (SED)
  • Supports Clone disk
  • Encryption at Rest Support ISE, TCG, SED, SSD with Block Erase & Password Protect

Advance Features & Benefits

  • Encryption at Rest Support ISE, TCG, SED, SSD with Block Erase and Password Protect
  • Exclusive Advanced Data Sentry technology (RAID 6) provides the highest level of data protection. Multiple simultaneous drive failures can be tolerated without downtime or data loss
  • Array Roaming feature gives administrators the ability to move a complete raid set to another system without losing RAID configuration and data on that raid set
  • Redundant Flash Image provides an extra layer of protection against the firmware image corruption. If the primary firmware of the RAID controller becomes corrupted, the secondary firmware image will automatically be used
  • Full 48-bit ATA addressing standard support allows for up to 144 petabytes capacity per drive to be utilized in the RAID array
  • ASIC assisted parity for lightning-fast throughput
  • RAID controller provides RAID 0, 0+1, 1, 3, 5, 6, 30, 50 and RAID 60, Global Hot Spare Disk, Auto Rebuild, and up to 4GB of DDR2 ECC SDRAM-based data cache
  • Intelligent SAS2 backplane design (uses no cables) allows “hot swapping” of disk canisters, power supplies, and fans for increased reliability, lower cost, and ease of maintenance
  • Built-in management Ethernet port provides easy access to the web-based GUI RAID Manager for configuration, management, and monitoring functions. E-mail event notification is built-in
  • Completely user configurable via the front panel
  • Scheduled Online Parity Consistency verification feature ensures RAID set integrity
  • Up to 128 addressable LUNS per RAID Set
