Abstract
Release Notes for IBM FlashCore Module (FCM) products
Content
1. Overview
The drive firmware upgrade process is non-disruptive. As a precaution, it is recommended that the upgrade occur during a time of reduced traffic as there may be an impact to performance. The impact is more noticeable under heavy load conditions. Schedule the FCM firmware updates during periods of low I/O or, optionally, schedule during a maintenance window.
Refer to Supported Drive Types and Firmware Levels for IBM Spectrum Virtualize Family of Products page for the supported drive firmware levels.
On the Fix Central Download page, refer to the file 'Which_NVME_File_should_I_use.txt' for guidance on which NVME package file is appropriate for your system.
2. New Features
The following features were released in Release 4.1.4.73
• Ransomware Threat Detection:
- is a process that identifies and responds to security threats before they can damage data or systems.
- uses information theory concepts such as Shannon Entropy and other statistics to characterize the current workload. This type of analysis requires byte-by-byte processing and is computationally expensive.
- FlashCore Module (FCM) drives provide computational storage offload to compute and summarize these statistics, which the FlashSystem aggregates and analyzes to notify Storage Insights of a potential threat. With drives that run FCM 4.1 firmware or later, statistics about data are processed within the FCM drives, and presented to the FlashSystem on a per volume basis. This is collected regularly, and aggregated across all participating drives, resulting in a set of statistics per volume. These statistics are then processed on the system to determine its threat potential.
3. Issues Resolved
Bug severity legend
The following table explains the bug severity ranking used for key fixes:
| Severity | Description |

|
Recommended upgrade for all users as soon as possible
|
|
S2
|
Recommended upgrade for all users at the next scheduled maintenance window
|
|
S3
|

|
|
S4
|
Upgrade at the next scheduled maintenance window. May be performed at the discretion of the user if the issue is having a negative impact
|
|
S5
|
Upgrade is not necessary. This would include a mostly cosmetic or minor annoyance fix
