System overview

Edit online

IBM® Storage FlashSystem 5300 is an NVMe storage option for entry-level enterprises that need compact and powerful storage.

Part of the FlashSystem family, the IBM Storage FlashSystem 5300 unifies data management across the core, cloud and edge, and is designed in a revolutionary 1U form factor. This configuration results in high speeds, robust density, and numerous scale-up and scale-out options. The IBM Storage FlashSystem 5300 has more compute power and double the internal bandwidth of its predecessor, the IBM Storage FlashSystem 5200.

IBM Storage Virtualize software

IBM Storage FlashSystem 5300 runs IBM Storage Virtualize which provides the following functions for the host systems that attach to the system:
  • A single pool of storage
  • Logical unit virtualization
  • Management of logical volumes
The software also provides the following functions:
  • Replication:
    • Simplify data management by automating configuration tasks.
    • Ensure seamless continuity while maintaining high throughput and low latency to applications.
  • Data reduction:
  • Ransomware threat detection enhanced with FlashCore Module 4 computational storage assists.
  • High-performance Distributed RAID for redundancy and fast rebuild
  • Large scalable cache
  • Easy to use management and automation that is consistent across the Storage Virtualize portfolio, including RestAPI, Ansible Playbooks, CSI integration, VMWare integration, and a modern Graphical User Interface (GUI).

For more information on IBM Storage Virtualize software, see the relevant IBM Documentation.

Note that some software features are subject to limits on this platform.

Control Enclosure

IBM Storage FlashSystem 5300 comprises a 1 Rack-Unit (1U) Control enclosure, which contains:
  • 12 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

IBM Storage FlashSystem 5300 supports the use of IBM FlashCore Modules, with inbuilt hardware compression and computational storage assists. The system also supports the use of Industry-Standard Flash Drives.
Note: Only drives that are sold as system options are supported.

Highly Available Architecture

IBM Storage FlashSystem 5300 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 5300 supports a range of Network Attachment adapter features.

The following adapter types are supported by the system:
Table 2. Adapter types
Adapter Type Protocols supported Minimum or maximum per node canister Minimum software level
Dual-port 64 Gbps Fibre Channel SCSI, FC-NVMe 0 - 2 8.7.0
Quad-port 32 Gbps Fibre Channel SCSI, FC-NVMe 0 - 2 8.6.3
Quad-port 10 Gbps Ethernet

Host I/O that uses iSCSI or NVMe/TCP

Replication over RDMA, TCP

Dual-port 12 Gbps SAS Expansion SAS (expansion) 0 - 1 8.6.3

In addition, each canister has three on-board Ethernet ports that are used for system management, replication, and Host I/O.

Power Supplies and Battery Backup

IBM Storage FlashSystem 5300 has two redundant Power Supplies.

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 5300 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.
