9831-AE2: 9831-AE2 IBM FlashSystem 820 Model 820
IBM Part Number: 9831-AE2
IBM FlashSystem 720 (9831-AS2) and FlashSystem 820 (9831-AE2) storage systems offer high performance, efficiency, and reliability for shared enterprise storage environments. These IBM storage systems may be used as data storage for large-scale applications that need low latency, such as large-scale databases and virtualization platforms.
These FlashSystem storage systems can work with or replace traditional hard drive arrays in many applications. As standard shared primary data storage devices, FlashSystem 720 and FlashSystem 820 storage systems deliver performance beyond that of most traditional arrays, even those that incorporate SSDs or other flash technology. FlashSystem 720 and FlashSystem 820 storage systems can also be used as the top tier of storage alongside traditional arrays in tiered storage architectures, such as the IBM Easy Tier functionality available in IBM System Storage SVC or Storwize V7000 storage virtualization platforms.
- Four 8 Gbps Fibre Channel (FC) or 40 Gbps quadruple data rate (QDR) InfiniBand interface ports
- Up to 10 TB of usable RAID 5 protected single-level cell (SLC) flash storage capacity (12.4 TB usable RAID 0, 16.5 TB raw capacity), or 20 TB of usable RAID 5 protected enterprise multi-level cell (eMLC) flash (24.7 TB usable RAID 0, 33.0 TB raw capacity) storage
- Dual power supplies with batteries to shut down safely in power loss events
- Web-based user interface with Service Center software for centralized and simplified service and support
- Four external interface ports, with a choice of either 8 Gbps FC or 40 Gbps QDR InfiniBand
