FlashSystem 5600 specifications
| Specification | Model detail |
|---|---|
| Machine type and model | 5127-A20 |
| Control enclosure | 1U |
| Internal drive positions | 12 EDSFF NVMe |
| System cache / memory | 256 / 512 GB |
| Published IOPS | Up to 2.6 million |
| Published bandwidth | Up to 30 GB/s |
| Capacity context | 633.6 TB nominal raw |
Published maxima describe specific test conditions. Application results depend on the drive population and RAID layout as well as block size, read/write mix and host connections.
FlashSystem 5600 drive choices and capacity
| Drive class | Supported source context |
|---|---|
| FCM5 | 6.6 TB; 13.2 TB; 26.4 TB; 52.8 TB |
| Standard EDSFF NVMe | 1.92 TB; 3.84 TB; 7.68 TB |
| Nominal installed raw | 12 x 52.8 TB = 633.6 TB before RAID and reserve |
Raw capacity is the installed media total before RAID and reserves. Usable capacity is what remains for data; effective capacity also assumes compression or other data reduction.
FlashSystem 5600 host connectivity
| Connection | Configuration |
|---|---|
| Standard | 10 / 25 Gb iSCSI or NVMe/TCP |
| Fibre Channel | 32 / 64 Gb FC or FC-NVMe |
| Ethernet options | 25 / 10 Gb or 100 / 40 Gb |
| Slots | Two adapter slots per node; sixteen optional I/O ports per enclosure |
FlashSystem 5600 expansion and scale
| Option | Model or limit |
|---|---|
| LFF | 4662-12G, twelve SAS drives |
| High density | 4662-92G, ninety-two SAS drives |
| SAS attachment | ALBQ attachment feature; up to six shelves in that feature description |
FlashSystem 5600 configuration limits and source differences
- The dedicated page gives 633 TBu / 2.5 PBe in one table and 633.6 TB raw in its introduction. The family overview gives 400 TBu / 2.4 PBe. These are different published capacity contexts, not one interchangeable usable figure.
- ADSN 105.6 TB is explicitly 9600-only on this source page; it is not a 5600 option.
- The source uses GB/s in some FC and Ethernet option labels but Gb/s in its adapter descriptions. The adapter rows below preserve their published bit-rate context.
5600 capacity and software
The dedicated page lists 8,192 host-mappable volumes and 16,050 snapshots. Effective capacity depends on data reduction; use RAID-usable capacity and workload data for the order.
FlashSystem 5600 software and IBM i attachment
We check the installed IBM Storage Virtualize or Spectrum Virtualize level against the proposed drives and adapters. Features such as replication, encryption and snapshots depend on the model, software level and entitlements.
For IBM i, send the Power model, IBM i release and host adapter details. We check direct or switched attachment and the supported protocol in the IBM System Storage Interoperation Center before finalizing the configuration.
FlashSystem 5600 data services and availability
- Policy-Based Replication and Policy-Based High Availability.
- FlashSystem Grid for supported workload movement and management across systems.
- Storage Insights monitoring with FlashCore hardware assistance for anomaly detection.
Room and upgrade requirements for FlashSystem 5600
- Identify the installation. Send the complete machine type, serial number and installed software level.
- Record capacity and workload. Include installed drive types, RAID layout and current usable space with peak IOPS and latency.
- Check rack and power. Record rail depth, service clearance and the existing outlet and PDU connections; include every expansion shelf.
- Plan attachment and migration. Include host adapters, switch models and optics with the available migration window.
