IBM TS7700, TS4500, Diamondback and DS8000 System Connectivity and Security v5.05

White Papers


Abstract

This document provides a comprehensive overview of the security architecture, connectivity mechanisms, and remote support capabilities for IBM’s enterprise storage systems: TS7700 Virtual Tape Library, TS4500 Tape Library, Diamondback Tape Library, and DS8000 Storage System. It is intended for IT administrators, architects, and security professionals deploying these systems in enterprise environments.
The primary focus is on the Call Home and Remote Access capabilities, which enable proactive support and diagnostics. It also details the security considerations when integrating these systems into a client’s network infrastructure, including access to web-based management interfaces (GUI), notification mechanisms like SNMP traps and Rsyslog, and integration with LDAP directories and Encryption Key Managers.

Key Products and Components
  • TS7700 Virtual Tape System: Grid-enabled virtual tape solution with advanced diagnostics, encryption, and LDAP integration.
  • TS4500 Tape Library: Modular tape storage with integrated management and remote support via IMC.
  • Diamondback Tape Library: Next-generation tape system with similar connectivity and security features as TS4500.
  • DS8000: High-performance disk storage system supporting cloud tiering and secure remote management.
  • TSSC/IMC: Centralized management console for TS7700, TS4500, and Diamondback.
  • HMC: Hardware Management Console for DS8000.
Core Processes and Features
1. Call Home
  • Heartbeat Call Home (HB CH): Periodic system health checks.
  • Error-Initiated Call Home: Triggered by system faults.
  • MRPD Call Home (DS8000 only): Periodic configuration reporting.
  • Data Routing: Secure transmission to ECuRep or Blue Diamond repositories.
  • Security: TLS-encrypted, outbound-only communication; no user data included.
2. Remote Access
  • Assist On-Site (AOS): Secure, TLS-based remote support tool with screen sharing and session recording.
  • Remote Support Center: SSH-based alternative for secure remote diagnostics.
  • Authentication: Multi-level access control with temporary credentials and IBM internal validation.
3. Connectivity Infrastructure
  • ECC (Electronic Customer Care): TLS 1.2 encrypted communication for problem reporting and fix downloads.
  • Proxy Support: Configurable for ECC and AOS with strict certificate validation.
  • ECuRep Upload: Manual or scheduled uploads via SFTP/HTTPS.
  • Blue Diamond Upload: Secure HTTPS upload for HIPAA-sensitive environments.
Security and Access Control
  • Service Access Levels:
    • Service, Enhanced, and Engineering levels with unique credentials.
    • Temporary passwords generated via IBM internal authentication servers.
  • LDAP Integration:
    • Supports Microsoft Active Directory, OpenLDAP, and RACF.
    • Enables centralized user management and role-based access.
  • System Managed Encryption:
    • Integrates with TKLM/ISKLM for secure key management.
Audit Logging and Monitoring
  • SNMP Audit Logging: Sends traps for user actions and system events (deprecated).
  • RSYSLOG Audit Logging: Modern alternative for centralized log management.
  • Firewall and Port Configuration: Detailed port usage tables for each system; all communication is outbound-only.
System-Specific Highlights
TS7700
  • Grid Communication: Secure inter-cluster communication.
  • AOTM (Autonomic Ownership Takeover Manager): Failover diagnostics.
  • Management Interface (MI): Web-based UI with configurable security policies.
TS4500 & Diamondback
  • Web Specialist Interface: Secure web-based management.
  • Integrated IMC: Provides remote support and call home capabilities.
DS8000
  • HMC-Based Management: Centralized control and diagnostics.
  • Transparent Cloud Tiering (TCT): Cloud object storage integration.
  • Advanced Object Store: Integration with TS7700 for object-based storage.
