  • How can I purchase support entitlements for DRBD on RHEL?
    *If the systems in question run RHEL and have entitlements for support from Red Hat, please contact LINBIT to purchase support for DRBD. Please visit Visit LINBIT's Support Page.

  • Who should I contact for support? Red Hat or LINBIT?
    LINBIT provides support for DRBD, whereas Red Hat provides support for RHEL. If any problem or question arises that spans DRBD and RHEL, or it is not obvious on which side the problem lies, Red Hat and LINBIT support teams will work together to help identify and address the issue or question.

  • What is DRBD?
    *DRBD is a Software-Defined Storage solution, used to provide high performance replicated block storage for any linux environment. As DRBD is in the mainline Linux kernel, it supports replication for any Linux OS on traditional, distributed, and cloud storage. Combined with the Linux HA stack, it allows for High Availability on any Linux system.

  • Will Red Hat Enterprise Linux 5, 6, or 7 include a kernel with DRBD support ?
