This knowledgebase article describes the best practice for block alignment on Nimble storage devices.


From a performance perspective, partition misalignment has a larger impact than IO size mismatches and therefore should always be avoided and resolved if possible. However, to gain the best possible performance efficiencies out of a Nimble array it is advisable to ensure IO sizes are also matched appropriately. Outlined below are the conditions where each type of block alignment issue can be observed and steps to take to resolve them.
