kernel-3.10.0-514.el7
Red Hat Compatible Kernel (RHCK).
kernel-uek-4.1.2-61.1.8.el7uek
Unbreakable Enterprise Kernel Release 4 (UEK R4), which is the default kernel.
Features that are currently under technology preview when using UEK R4u2 are described in <a href="http://docs.oracle.com/cd/E52668_01/E78976/html/index.html">Oracle Linux Release Notes for Unbreakable Enterprise Kernel Release 4 Update 2</a>.
For the RHCK, the following features are currently under technology preview:
Systemd:
* Importd features for container image imports and exports
File Systems:
* DAX (Direct Access) for direct persistent memory mapping from an application. This is under technical preview for the ext4 and XFS file systems.
* Block and object storage layouts for parallel NFS (pNFS).
* SCSI layout for parallel NFS (pNFS), including syupport for both client and server configurations.
* OverlayFS remains in technical preview.
* btrfs file system. Oracle supports btrfs with UEK R3 and UEK R4.
Kernel:
* Heterogeneous memory management (HMM).
* Usernamespace (security features for isolating Linux containers from the host).
* 10GbE RoCE Express for RDMA.
* ocrdma and libocrdma packages for RDMA over RoCE.
* No-IOMMU mode virtual I/O feature.
Networking:
* Support for a Cisco proprietary User Space Network Interface Controller in UCM servers provided in the libusnic_verbs driver
* Cisco VIC Infiniband kernel driver that provides similar functionality to RDMA on proprietary Cisco architectures.
* Trusted Network Connect.
* Single-Root I/O virtualization (SR-IOV) in the qlcnic driver.
* nftables and libnftnl network filtering and classification functionality
Storage
* LVM2 support for RAID-level takeover (striped RAID4, linear RAID1 and mirror RAID1)
* Multi-queue I/O scheduling for SCSI (scsi-mq). This functionality is disabled by default.
* The plug-in for the libStorageMgmt API used for storage array management. The libStorageMgmt API is now fully supported, but the plugin is under technology preview.
* DIF/DIX for data integrity checking on SCSI devices other than certain, specified native HBA and storage hardware. Oracle supports DIF/DIX with UEK R3 and UEK R4.
