FlashSystem 5045 specifications
| Specification | Model detail |
|---|---|
| Machine type and model | 4680-3P2; 4680-3P4 |
| Control enclosure | 2U |
| Internal drive positions | 12 LFF or 24 SFF SAS |
| System cache / memory | 64 GB total |
| Published IOPS | 1.2 million read hit |
| Published bandwidth | Up to 12 GB/s |
| Capacity context | 737.28 TB raw, 24 x 30.72 TB |
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 5045 drive choices and capacity
| Drive class | Supported source context |
|---|---|
| SFF SAS flash | AL80 to AL84: 1.92 TB through 30.72 TB |
| LFF nearline | AL3B to AL3J: 8 TB through 24 TB in the 12H context |
| High density | AL48 to AL4F: 8 TB through 24 TB in the 92H context |
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 5045 host connectivity
| Connection | Configuration |
|---|---|
| Standard | Four 10 Gb copper iSCSI ports |
| Optional | 16 Gb FC; 12 Gb SAS; 10 / 25 Gb optical iSCSI |
FlashSystem 5045 expansion and scale
| Option | Model or limit |
|---|---|
| LFF | 4680-12H, twelve drives |
| SFF | 4680-24H, twenty-four drives |
| High density | 4680-92H, ninety-two drives |
| System / cluster | 440 / 880 drives; shelf mix and software rules apply |
FlashSystem 5045 detailed hardware and feature tables

5045 cached-read and read-miss performance
| Measurement | Maximum | Test condition |
|---|---|---|
| Cached read IOPS | 1.2 million | 4 KB read hit |
| Read-miss IOPS | 400,000 | 4 KB read miss |
| Read bandwidth | 12 GB/s | 256 KB read miss |
FlashSystem 5045 configuration limits and source differences
- The current product table gives 737.28 TB raw for the 24-drive 3P4; the broad family overview gives 675 TB without the same capacity definition. RAID and spare space reduce usable capacity.
- The drive list uses 2072-2P4 / 3P4 labels beside the 4680-24H. Keep those exact ordering contexts and confirm the control-enclosure mapping.
FlashSystem 5045 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 5045 data services and availability
- Safeguarded Copy, FlashCopy and remote mirroring.
- HyperSwap and system clustering in supported configurations.
- Data-reduction pools with compression and deduplication; encryption of data at rest.
Room and upgrade requirements for FlashSystem 5045
- 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.
