| ====== PowerVM / VIOS Release NOTE ====== | ====== PowerVM / VIOS Release NOTE ====== | ||
| + | |||
| + | ===== PowerVM v4.1 ===== | ||
| + | |||
| + | AIX 7.3TL2 Benefits for VIOS 4.1 supported on Power 8, 9 and 10 | ||
| + | |||
| + | **Performance** | ||
| + | * Enhanced fork/exec performance | ||
| + | * Power10 optimized data movement (e.g.memcpy, memzero) | ||
| + | * Network and storage stack performance improvements | ||
| + | * HW GZIP for SSH/SCP, dump, and pigz | ||
| + | |||
| + | **Optimized Security** | ||
| + | * AIX program updates for OpenSSL 1.1 or later | ||
| + | * AIX audit check performance | ||
| + | * Security aligned install defaults for networking components | ||
| + | * SSHA-256 password algorithm | ||
| + | * Out of the box long password support (up to 255 chars) | ||
| + | * LVM Encryption option for VIOS rootvg and dump devices | ||
| + | |||
| + | **Security features** | ||
| + | * Supports Trusted Execution, Trusted Update and Secure Boot. | ||
| + | * VIOS boot is made more secure (Secure Boot) and only administrator allowed programs and Kernel Extensions can run with the Trusted Execution feature. This protects system from malicious software & trojans. | ||
| + | * Trusted Update feature ensures that only images that are digitally signed by IBM are allowed to update the existing filesets on the system. | ||
| + | * Default passwords are stronger with the SHA-256 algorithm and also support out of the box long passwords with the maximum of 255 characters. | ||
| + | * Physical volumes that uses the SCSI protocol can be encrypted with hdcryptmgr command (under oem_setup_env), using data encryption key. | ||
| + | * Data protection is enhanced with LVM encryption for rootvg and dump devices. | ||
| + | * Services that are not secure like rexec, rsh are removed. Telnet / ftp services are disabled. If required, users can enable telnet / ftp services. | ||
| + | * ksh93 is used as the default shell in VIOS commands and scripts | ||
| + | |||
| + | **Enhanced Availability** | ||
| + | * Enhanced LLDP reporting | ||
| + | * Enhanced MPIO (faster FC failover, FPIN traffic optimization) | ||
| + | * DLPAR performance for CPU and RAM changes | ||
| + | * Reduced boot time | ||
| + | * Enhanced concurrent change management | ||
| + | |||
| + | **Automation and Modernization** | ||
| + | * Python bundled for Ansible readiness | ||
| + | * Bash | ||
