Over the next few weeks we’ll be posting results from tests that we’ve run against various manufactures SSD drives; including Intel, SanDisk, and Micron, to name a few. The first post in this series goes over our findings of the Intel DC S 3700 Series 800GB SATA SSD drives.
DRBD9 has a new transport abstraction layer and it is designed for speed; apart from SSOCKS and TCP the next generation link will be RDMA. So, what is RDMA, and how is it different from TCP?
We often see people on #drbd or on drbd-user trying to measure the performance of their setup. Here are a few best practices to do this.
When DRBD 8.4.4 integrated TRIM/Discard support, a lot of things got much better… for example, 700MB/sec over a 1GBit/sec connection.
In the “Root-on-DRBD” Tech-Guide we showed how to cleanly get DRBD below the Root filesystem, how to use it, and a few advantages and disadvantages. Now, if there’s a complete, live, backup of a machine available, a few more use-cases become available; here we want to discuss testing upgrades of production servers.
