Control Enclosure
- 24 slots for NVMe Flash devices (front)
- Two Node Canisters
- Two Power Supplies.
The system can be expanded with the addition of SAS-based Expansion Enclosures.
NVMe Flash Devices
Highly Available Architecture
IBM Storage FlashSystem 7300 implements an Active-Active architecture, with the two Node Canisters forming a redundant I/O Group. Because data volumes are served by both node canisters, the volume remains available if one node canister fails or is taken offline.
Node canisters contain the systems CPUs, memory, backup batteries, and Network Attachment adapters.
Flexible Network Attachment
IBM Storage FlashSystem 7300 supports a range of Network Attachment adapter features.
| Adapter Type | Protocols supported | Minimum or maximum per node canister | Minimum software level |
|---|---|---|---|
| Dual-port 64 Gbps Fibre Channel | SCSI, FC-NVMe | 0 - 3 | 8.7.0 |
| Quad-port 32 Gbps Fibre Channel | SCSI, FC-NVMe | 0 - 3 | 8.5.0 |
| Dual-port 100 Gbps Ethernet | iSCSI, RoCE, NVMe/TCP |
0 - 3 |
8.5.0 |
| Dual-port 25 Gbps Ethernet (RoCE) | iSCSI, RoCE, NVMe/TCP |
0 - 3 |
8.5.0 |
| Dual-port 25 Gbps Ethernet (iWARP) | iSCSI, iWARP (Replication/High availability) |
0 - 3 |
8.5.0 |
| Dual-port 12 Gbps SAS Expansion | SAS (expansion) | 0 - 1 | 8.5.0 |
In addition, each canister has four on-board Ethernet ports that are used for system management, replication, and Host I/O.
Power Supplies and Battery Backup
IBM Storage FlashSystem 7300 has two redundant Power Supplies. The power supplies require a high-line (200 V - 240 V) AC power source.
Each node canister contains a Battery that allows a canister to save its cache and metadata in an unscheduled power-down event.
Enterprise Warranty and Services
IBM Storage FlashSystem 7300 is available with IBM Storage Expert Care, with several levels of support to suit different deployment models. Refer to IBM Enterprise Support and Preferred Care options for more information.
