Decrease your Amazon OpenSearch Service storage value with gp3 Amazon EBS volumes


Amazon OpenSearch Service makes it simple so that you can carry out interactive log analytics, real-time software monitoring, web site search, and extra. OpenSearch is an open-source, distributed search and analytics suite comprising OpenSearch, a distributed search and analytics engine, and OpenSearch Dashboards, a UI and visualization instrument. Once you use Amazon OpenSearch Service, you configure a set of information nodes to retailer indexes and serve queries. The service helps occasion sorts for information nodes with completely different storage choices. Some supported Amazon Elastic Compute Cloud (Amazon EC2) occasion sorts, just like the R6GD or I3, have native NVMe disks. Others use Amazon Elastic Block Retailer (Amazon EBS) storage.

On July 2022, OpenSearch Service launched assist for the following era, basic goal SSD (gp3) EBS volumes. OpenSearch Service information nodes require low latency and excessive throughput storage to supply quick indexing and question. With gp3 EBS volumes, you get increased baseline efficiency (IOPS and throughput) at a 9.6% decrease value than with the beforehand supplied gp2 EBS quantity sort. You may provision extra IOPS and throughput impartial of quantity dimension utilizing gp3. gp3 volumes are additionally extra secure as a result of they don’t use burst credit. OpenSearch assist for gp3 volumes consists of doubling the restrict on per-data node quantity sizes. With these bigger volumes, you possibly can scale back the price of passive information, growing the quantity of storage per node.

We suggest that you just think about gp3 as the very best Amazon EBS possibility for value/efficiency and adaptability. On this publish, I focus on the fundamentals of gp3 and varied cost-saving use circumstances. Migrating from earlier era storage (gp2, PIOPS, and magnetic) volumes to the most recent era gp3 volumes permits you to scale back month-to-month storage prices and optimize occasion utilization.

Evaluating gp2 and gp3

gp3 is the successor to the final goal SSD gp2 quantity. The important thing advantages of gp3 embody increased baseline efficiency, 9.6% decrease value, and the flexibility to provision increased efficiency no matter quantity. The next desk summarizes the important thing variations between gp2 and gp3.

Decrease your month-to-month payments with gp3

The power to provision IOPS and throughput impartial of quantity dimension and assist for denser (twice as giant) quantity sizes are two vital benefits of gp3 adoption. Collectively, these advantages allow a number of use circumstances to decrease your month-to-month payments. On this part, we current a number of examples of pricing comparisons for OpenSearch domains.

gp2 vs. gp3

That is the most typical situation, by which current gp2 prospects change to gp3 and instantly start saving 9.6% as a result of decrease month-to-month value per GB for gp3 storage. You too can profit from the truth that gp3 helps quantity sizes two occasions bigger for the R5, R6g, M5, and M6g occasion households. Which means you don’t must spin up new situations for denser storage necessities and might obtain increased storage on the identical occasion. OpenSearch Service at present helps a most of 24 TiB of gp3 storage on R6g.12Xlarge situations.

PIOPS (io1) vs. gp3

OpenSearch Service helps the PIOPS SSD (io1) EBS quantity sort. You may change to gp3 and provision extra IOPS and throughput to fulfill your particular efficiency necessities. The next desk compares the month-to-month value of PIOPS (io1) and gp3 storage with situations for storage necessities of 6 TiB and 16000 IOPS. On this instance, you’ll save 65% with gp3 adoption.

Optimize occasion value with gp3’s denser storage

OpenSearch Service elevated the utmost quantity dimension supported per occasion for gp3 by 100% when in comparison with gp2 for the R5, R6g, M5, and M6g occasion households resulting from gp3’s improved baseline efficiency. You may optimize your occasion wants by benefiting from the elevated storage per occasion quantity. For instance, R6g.giant helps as much as 2 TiB with gp3, however just one TiB with gp2. In the event you require assist for 12 TiB of information storage, you possibly can reconfigure your domains from six information nodes to a few R6g.giant with the intention to scale back your occasion prices. For OpenSearch EBS instance-specific quantity limits, confer with EBS quantity dimension quotas.

Improve from gp2 to gp3

To make use of the EBS gp3 quantity sort, you have to first improve your area’s situations to supported occasion sorts in the event that they don’t already assist gp3. For an inventory of OpenSearch Service supported situations, see EBS quantity dimension quotas. The transition from gp2 to gp3 is seamless. You may improve area configurations from current EBS quantity sorts resembling gp2, Magnetic, and PIOS (io1) to gp3 by OpenSearch Service console or the UpdatedomainConfig API. The configuration change will provoke blue/inexperienced deployment, which runs within the background with out impacting your on-line visitors and, relying on the info dimension, is full in a number of hours. Blue/inexperienced deployments run within the background, guaranteeing that your on-line visitors is uninterrupted and stopping information loss.

gp3 baseline efficiency, and extra provisioning limits

One of many gp3’s key options is the flexibility to scale IOPS and throughput impartial of quantity. When your software requires extra efficiency, you possibly can scale as much as 16,000 IOPS and 1,000 MiB/s throughput for a further charge. OpenSearch Service EBS gp3 delivers a baseline efficiency of three,000 IOPS and 125 MiB/s throughput at any quantity dimension. As well as, OpenSearch Service provisions extra IOPS and throughput for bigger volumes to make sure optimum efficiency. For volumes above 1,024 GiB, you obtain 3 IOPS/GiB, and for volumes above 170 GiB, you get an incremental 250 MiB/s for each 3 TiB of storage.

The next desk outlines OpenSearch Service baseline IOPS and throughput, in addition to the utmost quantity you possibly can provision. Be aware that your occasion sort could have extra limitations concerning how a lot and for a way lengthy it may well assist these efficiency baselines in a 24-hour interval. For extra details about situations and their limits, confer with Amazon EBS-optimized situations.

Do you want extra efficiency?

Within the majority of use circumstances, you don’t must provision extra IOPS and throughput, and gp3 baseline efficiency ought to suffice. You should utilize Amazon CloudWatch metrics to seek out the utilization patterns, and in the event you observe present limits of IOPS and throughput bottlenecking your index and question efficiency, you need to provision extra efficiency. For extra info, confer with EBS quantity metrics.


This publish explains how OpenSearch Service basic goal SSD gp3 volumes can considerably scale back month-to-month storage and occasion prices, making them cheaper than gp2 volumes. Migration to gp3 volumes with the identical dimension and efficiency configurations as gp2 is the quickest and easiest technique to scale back prices. Moreover, you must also think about lowering occasion prices by benefiting from gp3’s assist for denser storage per information node.
