Besides making RHEL more secure, Red Hat is also seeking to improve storage capacity by introducing virtual data optimizer (VDO). This is a technology derived from Red Hat’s acquisition of Permabit assets. It’s designed to reduce data redundancy through inline deduplication and compression.
The bandwidth and storage, which can be saved by VDO, is little short of amazing. Red Hat claims that, in a RHEL 7.5 primary storage environment, VDO can increase effective capacity by up to six times. This frees up existing storage and reduce the costs associated with offsite data replication. These savings, extended to public cloud block storage, can reduce storage footprints by up to 83 percent, helping to reduce the hourly cost for active storage and the monthly costs of storing snapshots. This will really help you to get the most from your existing storage services.
The new test RHEL also boasts enhanced sysadmin usability for Linux administrators, Windows administrators new to the platform, and developers seeking self-service capabilities. It does this with:
An easier-to-use Cockpit administrator console. The new Cockput makes it easier to manage storage, networking, containers, services, and more for individual systems.With RHEL 7.5, you can also automatically create a “known-good” bootable snapshot. This helps speed up recovery and rollback after patching.
