IBM Storage FlashSystem 5300 Review

The IBM FlashSystem 5300 isn’t only about high performance—it also delivers enterprise-grade resiliency and scalability.

The IBM FlashSystem 5300 is IBM’s answer to high-performance, cost-effective storage for the entry-level enterprise market. This 1U storage array features IBM’s FlashCore Modules, offering up to 1.8PB of effective storage capacity. The 5300 also packs features like AI-powered data management to provide high-speed storage with built-in data protection and reduction capabilities.

The IBM FlashSystem 5300 provides a top-line performance throughput of up to 28.6GB/s. Compared to the FlashSystem 5200, the 5300 achieves a 1.45x increase in real-world IOPS, from 270,000 to 400,000, and a 1.3x improvement in bandwidth, rising from 21GB/s to 28GB/s. These figures are based on a 16k block size, 70% reads, 30% writes, and a 50% cache hit workload.

FlashCore Modules: Key to IBM’s Storage Density and Performance

By integrating advanced data reduction technologies like inline compression and deduplication directly into the FlashCore Modules, the drives allow significantly more data to be stored in less physical space, optimizing the storage footprint. These proprietary NVMe-based “SSDs” are engineered to maximize density and efficiency without sacrificing performance. They are essential to the IBM FlashSystem 5300’s ability to deliver up to 1.8PB storage capacity in a 1U form factor.

Critically, the data reduction at the drive level means the CPU is free for other tasks. Inside each module is an AMD Xilinx SoC that handles the heavy lifting. Despite substantial investment, these drives belong to the computational storage category, which has not achieved broad success in the IT industry. That said, IBM Storage has sorted out the benefits, letting the FlashSsytem 5300 offer such robust capacity in 1U. In addition to compression, the FlashCore Modules handle encryption, ransomware threat detection, entropy management, and compression deltas.

IBM’s ongoing quest to offer future-proof solutions is evident in the 5300, a storage system designed to counter the threat of quantum computers breaking current encryption methods. The 5300 employs asymmetric cryptographic algorithms, including CRYSTALS-Dilithium for authentication and firmware verification and CRYSTALS-Kyber for secure key transport of unlock PINs from controllers to Flash Core Modules (FCMs).

Additionally, the system ensures data-at-rest security by utilizing XTS-AES-256 encryption for customer data stored in flash memory. As IBM continues to innovate with the FlashSystems, it represents an important step in providing long-term data protection and security assurance for organizations in an evolving technological landscape.

IBM Storage FlashSystem 5300 Specifications

The 5300 has dual controllers, or as IBM calls them, “Node Canisters,” in active-active configuration. These can be configured with various options to help data move across the network. The array has four onboard 25/10GbE Ethernet ports, supporting SFP28, SFP+, and RJ45 interfaces, allowing for high-speed data transfer and network flexibility. Additionally, the 5300 can be configured with up to 16 Fibre Channel host ports, supporting either 32Gb or 64Gb FC, providing robust connectivity for high-performance workloads.

Interface and Management

The IBM FlashSystem 5300 integrates AI-powered management through IBM Storage Insights, a cloud-based tool that provides advanced monitoring, analytics, and predictive maintenance to optimize storage operations. By leveraging AI, Storage Insights helps businesses monitor performance, detect potential issues early, and predict future capacity needs based on historical usage trends. This reduces manual intervention and ensures that systems remain healthy and secure. Additionally, the FlashSystem 5300’s user-friendly GUI simplifies day-to-day management tasks, allowing administrators to easily configure and monitor the system without requiring extensive storage expertise.

The 5300’s Web management UI has a thoughtful design and user-centric functionality. Upon first login, administrators are greeted with a sleek, minimal interface. The dashboard presents a clear, at-a-glance overview of the system’s health, capacity utilization, and performance metrics, allowing IT professionals to quickly assess the array’s status. Navigating the various sections is intuitive, with a logical menu structure, making management tasks straightforward.

Thanks to well-designed wizards and form layouts, users can add hosts, configure storage pools, and manage volumes through streamlined processes that can be completed in just a few clicks. Performance monitoring is easy, with real-time graphs and charts displaying crucial metrics like IOPS, latency, and throughput. The interface’s responsiveness ensures that even complex operations like setting up replication feel swift and effortless. This combination of feature-rich functionality and ease of use significantly reduces the learning curve for new administrators while providing the depth and control that experienced professionals demand.

IBM Storage FlashSystem 5300 Performance

Test Setup:

IBM FlashSystem 5300

• 12 x 9.6TB SSDs
• 128GB Cache

Dell PowerEdge R760

• 2 x Intel Xeon 8592+ CPUs
• 24 x 64GB DDR5 RAM
• 4 x Dual-Port Emulex 32Gb FC HBA
• Windows Server 2022

When testing the IBM FlashSystem 5300, we leveraged a direct-connected approach with a single client-server. On the client, we installed four dual-port 32Gb Emulex HBAs and connected each port directly to the storage array for peak performance. The test layout for the storage used a RAID-DP storage pool, which we then carved out eight 1TB volumes.

Sequential Performance: The 5300 demonstrates impressive sequential read performance, peaking at 25.2 GB/s for 128K blocks. Sequential write performance, while lower, remains competitive at 9.1 GB/s for 128K blocks.

Random Performance: In random access scenarios, the system’s in-cache performance is notably robust, reaching 547K IOPS for 4K random reads.

Mixed Workloads: For mixed read/write scenarios, performance scales well as the read percentage increases, with the 90/10 read/write mix for 8K blocks achieving 442K IOPS and 3.6 GB/s bandwidth.

Transparent Pricing

It is not exactly a feature, but one standout decision IBM has made is publicly listing pricing for the FlashSystem 5300, a relatively uncommon practice in the enterprise storage industry. Most vendors require customers to go through lengthy sales processes or negotiations to obtain pricing information, but IBM takes a more transparent approach with the 5300. By providing straightforward, upfront pricing, IBM helps organizations make more informed decisions about their storage investments without opaque pricing structures’ typical delays or uncertainties.
