LENOVO - 00MJ101 - V3700 4GB TO 8GB CACHE UPGRADE

IBM 00MJ101 V3700 4GB to 8GB Cache Upgrade

The IBM 00MJ101 is a controller cache upgrade for IBM Storwize V3700 storage systems, increasing cache capacity from 4GB to 8GB to help improve responsiveness for reads/writes and mixed I/O workloads. It is typically used when a V3700 is supporting virtualisation datastores, consolidated SAN workloads, or general-purpose storage where latency consistency matters.

This part is intended for the IBM Storwize V3700 platform and should be matched to the correct controller generation/FRU during maintenance planning. For broader platform sourcing, you can browse related refurbished IBM hardware. Cache and memory-related upgrades are installed on or alongside the controller hardware and its SYSTEM BOARD, so verifying compatibility before a change window is recommended.

In performance tuning projects, cache expansion is often paired with compute-side headroom such as additional CPU resources on the host side, especially where queue depth and application concurrency are being increased.

Key Features

Key technical characteristics for professional deployment and maintenance planning:

• 4GB to 8GB cache expansion to increase controller cache resources for improved responsiveness under active workloads.
• Designed for IBM Storwize V3700 controllers to maintain compatibility within the V3700 platform architecture.
• Compatible with IBM Storwize V3700 storage system families (V3700 array/controller family) for in-place upgrades without changing the array form factor.
• Controller-level cache upgrade component to help reduce back-end disk impact by absorbing bursts and repeated reads.
• Enterprise storage upgrade part to support 24/7 operation and maintenance in production environments.
• Intended for planned service procedures to help shorten maintenance time compared with full controller replacement.
• Suitable for mixed SAN workloads (virtual machines, databases, file services) to help stabilise performance during peak I/O periods.
• Practical lifecycle extension option for existing V3700 deployments to keep established storage estates operational longer.

Refurbished Quality and Warranty

This unit is refurbished hardware, cleaned and tested by technicians before entering stock to help reduce the risk of hardware defects. Refurbished upgrades are a practical way to extend the lifecycle of installed storage platforms, reduce electronic waste, and control budgets compared to buying new.

Direct Hardware Supply is an international supplier of refurbished IT hardware, shipping worldwide from Denmark. This product includes a one-year warranty from the date of purchase (batteries, tape drives and tape libraries include three-month warranty), and extended warranty options are available on request.

For end-to-end infrastructure sourcing around your storage environment, we can also support compatible RACK SERVER deployments used for hypervisors, backup repositories, or management tooling.
