The following IBM enterprise storage categories provide a starting point for comparing storage technologies and locating specific models, machine types and replacement parts.

IBM Enterprise Storage Categories

IBM FlashSystem Enterprise Storage

IBM FlashSystem is IBM's family of enterprise flash and hybrid storage platforms. Modern FlashSystem systems combine NVMe storage, IBM FlashCore Module technology and IBM Storage Virtualize software with enterprise data services such as snapshots, replication, thin provisioning, data reduction, encryption and cyber-resilience capabilities.

The FlashSystem family spans compact storage systems through large enterprise NVMe platforms. Midland provides current and previous-generation FlashSystem systems as well as FlashCore Modules, NVMe drives, SAS drives, expansion enclosures, host adapters and service parts.

IBM Storwize V7000 Storage Systems

IBM Storwize V7000 is a family of enterprise virtualized storage systems based on IBM's Storwize and Spectrum Virtualize architecture. V7000 systems can manage internal storage and, in supported configurations, virtualize external storage behind the same management and data-services layer.

The V7000 family spans multiple controller generations, from the original 2076-112/124 systems through enhanced Gen1 models, Gen2 and Gen2+, and the NVMe-capable Gen3 2076-724.

Expansion options include 2076-24F SFF, 2076-12F LFF, 2076-92F high-density, 2076-224 SFF and 2076-212 LFF expansion enclosures, depending on controller generation and software level.

IBM DS8000 Enterprise Storage

The IBM DS8000 family represents IBM's high-end enterprise storage architecture for large, mission-critical workloads. DS8000 systems have historically been deployed where performance, availability, advanced replication and enterprise-scale storage management are primary requirements.

Midland's DS8000 product coverage includes systems such as the DS8700, DS8800 and DS8870 generations, including all-flash and hybrid storage configurations.

DS8000 environments are commonly associated with:

• Mission-critical enterprise databases
• IBM mainframe storage
• Distributed enterprise servers
• High-availability applications
• Large-scale storage consolidation
• Business analytics
• Disaster recovery and replication

IBM SAN Volume Controller

IBM SAN Volume Controller provides a storage virtualization layer that can consolidate and manage supported storage resources across a SAN environment.

Rather than requiring applications to interact directly with each physical storage array, storage virtualization can provide a common logical layer for capacity provisioning, migration, replication and management.

Typical SAN Volume Controller applications include:

• Storage consolidation
• External storage virtualization
• Online data migration
• Centralized SAN management
• Extending IBM storage services to supported third-party storage
• Business-continuity architectures

IBM Tape Drives and Tape Libraries

IBM tape storage provides removable media for backup, long-term archive, disaster recovery and offline data retention. Tape can provide a physically disconnected copy of important information after cartridges are removed from production systems, making it useful within broader cyber-recovery strategies.

Midland provides standalone IBM LTO tape drives, automated tape libraries, enterprise tape systems, LTO media and replacement tape hardware.

IBM Standalone LTO Tape Drives

IBM Tape Libraries

IBM automated tape libraries provide multiple cartridge slots and one or more tape drives so backup software can load and unload media automatically.

Representative Midland tape-library coverage includes:

• IBM TS2900 LTO 3572 Tape Autoloader
• IBM TS3100 LTO 3573 Tape Library
• IBM TS3200 LTO 3573-L4U Tape Library
• IBM TS4300 3555 modular tape library
• IBM TS4500 enterprise tape library

IBM i Virtual Tape Library Backup

An IBM i Virtual Tape Library (VTL) provides disk-based tape emulation for IBM i backup and recovery. A VTL can present virtual tape drives and cartridges to IBM i while storing backup data on disk-based storage rather than requiring every save operation to write directly to physical tape.

Midland's IBM i VTL solutions provide options for high-speed backup, parallel backup streams, replication, cloud archive, encryption, immutable backup retention and disaster recovery.

VTL technology can complement rather than completely replace tape. For example, daily backups can be written quickly to VTL storage while selected backup sets are subsequently copied to physical LTO tape or replicated to another site.

Flash Storage vs. Disk vs. Tape vs. VTL

Different IBM enterprise storage technologies solve different problems. A complete storage architecture may use more than one storage class.

IBM Storage for IBM Power Systems

IBM enterprise storage is widely used with IBM Power Systems running IBM i, AIX and Linux. Different storage platforms provide different combinations of Fibre Channel, NVMe/FC, iSCSI, NVMe/TCP and SAS connectivity.

Typical IBM Power storage applications include:

• IBM i and Db2 for i
• AIX databases and applications
• SAP
• Oracle Database
• ERP systems
• PowerVM virtualization
• High availability and disaster recovery
• Development and test environments
• Enterprise backup
• Long-term archive storage

IBM Storage Upgrades and Replacement Parts

Existing IBM storage systems can often be expanded or maintained using supported replacement and upgrade components. Compatibility depends heavily on the exact machine type, model and software level.

Common IBM storage upgrade and replacement components include:

• IBM FlashCore Modules
• NVMe flash drives
• SAS SSDs
• SAS hard drives
• Storage expansion enclosures
• Node canisters and controllers
• Cache and memory upgrades
• Fibre Channel adapters
• Ethernet adapters
• SAS adapters and cables
• SFP and QSFP transceivers
• Power supplies and batteries
• Tape-drive mechanisms
• Tape-library components
• LTO cartridges and cleaning media

Choosing an IBM Enterprise Storage System

The correct IBM storage architecture depends on the application rather than capacity alone. Important considerations include:

• IOPS requirements for transactional and database workloads
• Latency requirements for response-sensitive applications
• Bandwidth for analytics, backup and large sequential workloads
• Usable and effective capacity
• Host connectivity such as Fibre Channel, NVMe/FC, iSCSI or SAS
• Availability requirements
• Replication and disaster recovery
• Cyber-resilience requirements
• Backup and retention periods
• Offline and off-site storage requirements
• Existing IBM Power Systems compatibility
• Future expansion requirements
