Configuring Tiered Storage in CloudStack Using LINSTOR
One of the benefits of integrating LINSTOR®, the LINBIT® developed software-defined storage utility, with Apache CloudStack is that you can use it to compliment CloudStack’s disk offerings to provide tiered storage within CloudStack. Tiered storage just means different types of storage, for example, faster or slower storage. Having tiered storage within a system or platform […]
Distributing Volume Replicas for High Availability & Disaster Recovery Using LINSTOR
LINSTOR® has supported using auxiliary node properties to fine tune LINSTOR’s logic for where in the cluster LINSTOR should place DRBD® volume replicas when you don’t explicitly name nodes. The auxiliary properties, also known as “AuxProps”, are key value pairs placed on nodes in a LINSTOR cluster. When you combine auxiliary node properties with LINSTOR options such […]
