 The allocation of indices in an {{es}} deployment can be allocated on [data tiers](../../manage-data/lifecycle/data-tiers.md).

 Distributing copies of the data (index shard replicas) on different nodes can parallelize processing requests thus speeding up search queries. This can be achieved by increasing the number of replica shards up to the maximum value (total number of nodes minus one) which also serves the purpose to protect against hardware failure. If the index has a preferred tier, Elasticsearch will only place the copies of the data for that index on nodes in the target tier.

 Elasticsearch standardized the implementation of [hot-warm-cold architectures](https://www.elastic.co/blog/elasticsearch-data-lifecycle-management-with-data-tiers) to [data tiers](../../manage-data/lifecycle/data-tiers.md) in version 7.10. Some indices and deployments might have not fully transitioned to [data tiers](../../manage-data/lifecycle/data-tiers.md) and mix the new way of implementing the hot-warm-cold architecture with [legacy](../../deploy-manage/distributed-architecture/shard-allocation-relocation-recovery/index-level-shard-allocation.md) based node attributes.
