Monitoring Disk I/O on Linux systems is one of the most common task to follow when analyzing the current performance status of a system and trying troubleshoot/optimize an existing environment, when talking about storage and volumes. Read More …
SSD caching, as usually even other forms of caching, is a computing technology that stores frequently used data to fast cache. This boosts IOPS performance and reduces latency, significantly shortening load times and execution. Caching works on both reads and writes, and particularly benefits read-intensive applications. Caching approach is not new to hard drives, and computing in general. Operating systems like Windows and Linux come with native caching software. Read More …
In VMware virtualization environments (as a rule in clustering scenarios) it may be necessary to share the same disk (vmdk or RMD) between 2 (or more) virtual machines (VMs) on VMWare ESXi. The most optimal way is to use the vmdk disk physically located on the shared storage or locally on the ESXi host and this can be done following some specific configurations to be able to access data between different VMs on the same storage.

CSV (Cluster Shared Volumes) is a feature in Windows Server family in which shared disks are concurrently accessible to all nodes within a failover cluster. The feature was first introduced in Windows Server 2008 R2 as a way to simplify storage with clustered Hyper-V virtual machines (VMs), but this is not limited to Hyper-V applications. Read More …
