Introduction Data Availability ensures reliable access to information, a critical requirement from any storage provider. This concept involves the infrastructure, systems, processes, and policies organizations use to keep data accessible and usable for authorized users. As data volume and complexity grow, organizations allocate more resources to maintain reliability. However, in a TCP/NVMe storage environment, resource scaling has practical limits. This blog shows a scenario where multiple NVMe namespaces are allocated to an ESXi host through multiple NVMe subsystems and controllers. Such configurations can lead to resource exhaustion during error ...

Dynamic Provisioning Pool Creation Using CCI

By Avinash Kumar Kushwaha posted 12-23-2024
25 people like this.
Introduction Data is a critical asset, and as data volumes increase, additional storage space becomes essential. By combining disks of varying capacities, such as 1TB, 3TB, and 5TB, you can create a storage pool with a total capacity of 9TB. On this pool, you can allocate multiple virtual chunks of different sizes for writing data. These chunks reserve their full capacity, even if no data resides on them. This concept is known as thick provisioning . Dynamic Provisioning Pool (DP-Pool) or thin provisioning addresses this limitation by dynamically allocating storage capacity based on actual data usage. Thick Provisioning versus ...
