2025年3月18日 · vSAN Express Storage Architecture (vSAN ESA) is the recommended architecture over vSAN Original Storage Architecture (vSAN OSA), especially for new deployments starting with vSAN 8.0. vSAN ESA is designed to process and store data with all new levels of efficiency, scalability, and performance.

VMware® vSAN™ is a hyperconverged, software-defined storage platform fully integrated with VMware vSphere®. New to the Guide is content for the Express Storage Architecture™ in vSAN 8 and vSAN 8 U2. vSAN ESA is supported on ReadyNodes that can be customized For information on customization of these ESA ReadyNodes see this blog and additional

2022年10月24日 · What is vSAN 8 Express Storage Architecture ESA? The new vSAN 8, the latest version, Express Storage Architecture is a new way to configure vSAN storage to take advantage of new advancements in storage architecture and new hardware capabilities.

vSAN offers deterministic space efficiency capabilities through data placement schemes that are optimized for storing data in a resilient but efficient manner. This includes RAID-5/6 erasure codes.

How does the vSAN ESA deliver the performance of RAID-1 mirroring while using RAID-5/6 erasure coding? 17 Does the ESA in vSAN 8 U1 through U3 offer better performance than the ESA found in vSAN 8?

2023年1月1日 · The vSAN Express Storage Architecture (ESA) introduced in vSAN 8 and enhanced in vSAN 8 through U3 delivers new capabilities that are unachievable in the vSAN Original Storage Architecture (OSA). As a result, guidance to achieve optimal performance in the ESA is different than recommendations found for the OSA.

2024年5月28日 · VMware vSAN ESA uses NVMe drives, higher CPU core counts, and high-speed networks to offer a simpler, more balanced design with higher overall performance. To run vSAN ESA it is highly recommended to run nodes with at …

2022年8月30日 · This new architecture will showcase some innovative ways of processing and storing data. vSAN 8 with ESA will introduce structural changes like a new log-structured file system (vSAN LFS), a new write-optimized log-structured object manager, and a …

2023年1月1日 · vSAN 8 introduces a new architecture known as the vSAN Express Storage Architecture (ESA). As an optional architecture to the Original Storage Architecture (OSA) found in previous versions of vSAN, as well as vSAN 8, the ESA delivers all-new capabilities not possible with the OSA.

In vSAN Express Storage Architecture (ESA), all storage devices claimed by vSAN contribute to capacity and performance. Each host's storage devices claimed by vSAN form a storage pool. The storage pool represents the amount of caching …
