single iod 400u

In this version, the bluestore spdk feature is enabled and bugs are fixed. Some basic optimizations are also made, such as CRC instruction optimization and thread polling optimization. In addition, the disk I/O statistics tool cephioceph.py is added. After executing "patch -p1 < ceph-optimization.patch", you can find cephistat.py in the root directory
(1) Based on Ceph v14.2.10, open source code can be downloaded from the following website:
https://download.ceph.com/tarballs/ceph-14.2.10.tar.gz
(2) Replace the default SPDK version of Ceph-14.2.10 with the SPDK version of EulerOS by referring to the guide.
(3) The optimized patch is ceph-Optimization.patch.
Download ceph-optimization.patch, merge it into ceph-14.2.10, and execute patch -p1 < ceph-optimization.patch.
Compile the Ceph RPM installation package.

ksal ec plugin

This release enables the KSAL EC algorithm on Ceph.
The KSAL is developed by Huawei. It contains the EC, CRC16 T10DIF, and CRC32C algorithms.
Based on the Huawei-developed vectorized EC codec solution, the EC algorithm replaces the high-order finite field GF(2^w) multiplication required in the erasure coding process with binary matrix multiplication through isomorphism mapping, so as to use exclusive or (XOR) instead of complex finite field multiplication that is implemented through table lookup. In addition, the EC algorithm uses an encoding orchestration algorithm to multiplex intermediate results in the parity block calculation process, which reduces XOR operands and accelerates encoding by working with Kunpeng vectorized instructions. Compared with open source EC, the KSAL EC algorithm has better performance.
