The NetApp DS2246 / NAJ-1001 is a high-density 2U 2.5-inch small form factor (SFF) expansion shelf designed to deliver performance-driven storage expansion for NetApp FAS/AFF arrays and IBM System Storage Nseries systems (N6000 and N3000 series). Featuring 24 drive bays in a compact 2U chassis, the NAJ-1001 doubles the drive density of standard 3.5-inch shelves, providing high-performance IOPS and bandwidth while drastically reducing data center rack footprint and power consumption.
Equipped with dual hot-swappable IOM6 (6 Gbps SAS) controllers, the DS2246 offers multipath resiliency, continuous fault tolerance, and direct connectivity to storage controllers or server HBAs via high-speed QSFP SAS links. Whether populated with high-speed enterprise 10K/15K RPM SAS hard drives or ultra-low-latency SAS SSDs, the NAJ-1001 is a proven workhorse for enterprise SAN/NAS virtualization, database workloads, and high-performance tier-1 storage expansion.
Key Features & Highlights- 2U 24-Bay High-Density Storage: Accommodates up to 24x 2.5-inch Small Form Factor (SFF) SAS HDDs or SSDs in a 2U rack enclosure.
- High-Performance 6 Gbps SAS Connectivity: Dual IOM6 controller modules deliver 6 Gbps per lane SAS throughput for low-latency, bandwidth-heavy data transfers.
- Universal FAS / Nseries Compatibility: Fully compatible with NetApp FAS/AFF controllers as well as IBM System Storage Nseries enterprise platforms.
- Full Hardware Redundancy: Dual hot-swappable IOM6 modules and dual redundant, hot-swappable integrated power supply and cooling fan assemblies ensure continuous uptime.
- Flexible Drive Media Options: Supports high-speed 10K/15K RPM enterprise SAS hard drives and high-endurance enterprise SAS SSDs.
- Multipath I/O Resiliency: Supports dual-loop and multipath high-availability configurations to prevent single points of connectivity failure.
- Efficient Energy & Thermal Management: Compact 2.5-inch drives consume up to 50% less power per drive compared to traditional 3.5-inch drive shelves.
