What is Linstor Gateway?
Linstor Gateway is an addon module for LINSTOR to export replicated resources to ISCSI and NFS layer. With gateway you can easily create iSCSI targets or NFS exports.
How fast is DRBD? Does it limit the IO of the backing disk?
DRBD is the fastest replication technology in the LINUX world. We recently hit the World IOPS Record, which is 14.8 Million. However, creating another layer in the data path will always create some latency and drop the IO. You can expect very little performance drop when you are replicating the data.
Can I use DRBD for backups?
DRBD is a technology that replicates data in realtime. It’s not a backup solution. However, you can create snapshots within LINBIT SDS (LINSTOR) using LVM and DRBD and then ship them in another storage for backup purposes.
Is there a limitation for DRBD Proxy Cache?
Yes, there are limitations. Proxy stores caching data inside of the RAM. Thus, the limitation is based on the amount of RAM in the proxy machine.
Should I install DRBD Proxy on the same machine or separate?
You can install DRBD Proxy on the same machine or separate machines. DRBD Proxy uses RAM as a buffer, so depending on your workload and requirements it may make sense to use a separate machine. In circumstances where you have numerous resources going through a single proxy a separate machine is highly recommended. DRBD Proxy […]
How can I install DRBD or LINSTOR?
There are several ways to install our software. Our software is open source, users can download from the source from GitHub, tarballs from our website or in pre-compiled binaries (deb and rpm) using our customer repositories. A paid support subscription is required for the pre-compiled binaries. Please contact us via our Contact Us page for […]
Does DRBD support synchronous and asynchronous replication?
Yes it can work with both. With DRBD you can choose different sync methods for each volume in a single cluster. While synchronous is used in a datacenter or local replication, asynchronous is preferred for long distance replication in most circumstances.
Can I use LINBIT HA (DRBD + pacemaker) in SAP database workloads?
Yes. LINBIT HA (DRBD) is application agnostic and can be used for any database workload.
What platforms are supported in DRBD & LINSTOR?
We always try to be up-to-date with the latest releases of Linux distributions. Please check our Support page for more information.
Do you work with databases?
LINBIT SDS or LINBIT HA is perfectly suited for database workloads and structured data. We’ve reached up to 400,000+ IOPS for a single volume.
