Alibaba Cloud provides ESSD AutoPL disks based on Enterprise SSDs (ESSDs). ESSD AutoPL disks inherit the features and performance of ESSDs and decouple disk capacity from disk performance. When you configure the capacity of ESSD AutoPL disks, you can configure provisioned performance and burst performance settings for the disks based on your business requirements. This topic describes the features, specifications, billing methods, and use scenarios of ESSD AutoPL disks and provides examples on how to configure the disks.

Note

  • The instance to which an ESSD AutoPL disk is attached exerts pressure on the ESSD AutoPL disk. The performance of all applications that run on the instance, such as Alibaba Cloud Security, CloudMonitor, and Cloud Assistant, is included in the performance statistics of the ESSD AutoPL disk.

  • For information about common performance metrics of disks, see the Performance metrics section of the "Block storage performance" topic.

  • For information about ESSDs, see ESSDs.

Features

The total performance of an ESSD AutoPL disk is the sum of the baseline performance, provisioned performance, and burst performance.

  • Baseline performance

    The baseline performance and pricing of an ESSD AutoPL disk is equivalent to the performance and pricing of an ESSD at performance level 1 (PL1 ESSD) that has the same specifications.

  • Provisioned performance

    The performance provision feature allows you to configure provisioned performance settings for ESSD AutoPL disks to meet storage requirements that exceed the baseline performance without the need to extend the disks. This decouples disk capacity from disk performance.

  • Burst performance

    By default, the performance burst feature is enabled for ESSD AutoPL disks. The feature allows ESSD AutoPL disks to burst their performance when spikes in read/write workloads occur and reduce the performance to the baseline level at times of normal workload. An ESSD AutoPL disk can deliver up to 1,000,000 IOPS, a maximum throughput of 4 GB/s, and a maximum performance density of 1,000 IOPS per GiB.

Scenarios

In addition to the scenarios for which ESSDs are suitable, such as latency-sensitive applications and I/O-intensive workloads, ESSD AutoPL disks are suitable for the following scenarios:

  • Scenarios in which disk performance needs to be increased without extending disk capacity.

  • Scenarios in which business workloads greatly fluctuate and require disks to burst their performance in response to workload spikes.

  • ②: indicates the provisioned performance that an ESSD AutoPL disk can deliver in addition to baseline performance.

  • ③: indicates the burst performance that an ESSD AutoPL disk can deliver, in addition to baseline performance and provisioned performance. You can use CloudLens for EBS of Elastic Block Storage (EBS) to monitor the performance burst details of an ESSD AutoPL disk in real time, including the burst duration and the number of burst IOPS. For more information, see the "View the burst performance data of an ESSD AutoPL disk" section of the Analyze disks topic.

  • ④: I/O density = Number of IOPS/Disk capacity. Unit: IOPS per GiB.

Note

The read/write performance of disks is limited by instance types and disk specifications and cannot exceed any of the limits specified by the instance types or disk specifications. For example, if the maximum disk bandwidth allowed for an instance type is 6 Gbit/s, which can be converted to 750 MB/s, the throughput of each disk on an instance of the instance type cannot exceed 750 MB/s.

  • For information about the disk IOPS and bandwidth supported by different instance types, see Overview of instance families. If a disk cannot deliver its maximum performance due to the limits of an instance type, we recommend that you upgrade the instance type.

  • For information about the relationship between instance types and storage I/O performance, see the Relationship between instance types and storage I/O performance section of the "Storage I/O performance" topic.

Supported instance families

ESSD AutoPL disks support the same instance families as ESSDs. For information about instance families, see Overview of instance families.

Billing

Billable items and billing rules

You are charged disk capacity fees, provisioned performance fees, and burst performance fees for ESSD AutoPL disks. For information about the billing rules of ESSD AutoPL disks, see Block storage devices.

  • Disk capacity fees: You are charged for the disk capacity of each ESSD AutoPL disk. The baseline performance of an ESSD AutoPL disk is equal to the baseline performance of an ESSD at performance level 1 (PL1 ESSD) that has the same capacity as the ESSD AutoPL disk.

  • Provisioned performance fees: You are charged for the provisioned performance of ESSD AutoPL disks based on the pay-as-you-go billing method.

  • Burst performance fees: You are charged for the burst performance of ESSD AutoPL disks based on the pay-as-you-go billing method.

    • Total number of burst I/Os per hour <= 100,000: All I/O bursts are covered by a free quota of 100,000 burst I/Os. You are not charged burst performance fees.

    • Total number of burst I/Os per hour > 100,000: Fee cap rules apply to keep the fees that are imposed on burst I/Os bounded. This way, you can achieve high performance without the need to worry about excessive burst performance fees. For more information, see the Burst performance fee cap rules section of this topic.

Burst performance fee cap rules

In extreme business scenarios, a higher-than-expected number of burst IOPS may result in excessive burst performance fees. To resolve the preceding issue, burst performance fee cap rules are applied to ESSD AutoPL disks to limit burst performance fees within a controllable range even in extreme cases.

  • Fee cap rules

    A fee cap rule is triggered to limit burst performance fees when the maximum burst I/O density exceeds 200 IOPS per GiB. The maximum burst I/O density is calculated by using the following formula: Maximum burst IOPS/Disk capacity. The following table describes the burst performance fee cap rules.

    Note

    Burst IOPS excludes the baseline IOPS and the provisioned IOPS.

    No fee (free quota of 100,000 burst I/Os)

    I/O glitches occasionally occur.

    Greater than 100,000

    Up to 200

    Not capped

    Fee = (Number of burst I/Os - 100,000) × Unit price of performance bursts. The price of performance bursts is measured in USD per 10,000 I/Os.

    Business spikes occasionally occur, but the number of burst IOPS does not exceed the threshold for limiting burst performance fees.

    Greater than 200

    Capped

    Fee = min((Number of burst I/Os - 100,000) × Unit price of performance bursts, Disk capacity fee × 8). The price of performance bursts is measured in USD per 10,000 I/Os.

    Disks are under extreme workload that requires high IOPS for an extended period of time.

  • Billing examples for cost savings

    For example, in the China (Hangzhou) region, a 40 GiB ESSD AutoPL disk bursts its performance for 1 hour while the disk is being used. The total number of burst I/Os during the hour is 4,390,000, and the maximum burst I/O density during the hour is 230 IOPS per GiB, which triggers the burst performance fee cap rule to limit the burst performance fees. The following table describes the comparison between the burst performance fees before being capped and the burst performance fees after being capped.

Pricing

For information about the pricing of ESSD AutoPL disks, see the Pricing tab of the Elastic Compute Service (ECS) product page.

Impacts of overdue payments

If your Alibaba Cloud account has overdue payments for the provisioned performance and the burst performance of ESSD AutoPL disks, Alibaba Cloud stops providing the performance provision feature and the performance burst feature for ESSD AutoPL disks. The baseline performance of the ESSD AutoPL disks is not affected. If you want to continue using the performance provision feature and the performance burst feature for the ESSD AutoPL disks, you must complete the overdue payments. After you complete the overdue payments, the performance provision feature and the performance burst feature become available for the ESSD AutoPL disks.

Configure the provisioned performance and the burst performance of an ESSD AutoPL disk

You can create an ESSD AutoPL disk separately or together with an ECS instance in the ECS console based on your business requirements.

    • Provisioned performance fee: Unit price of provisioned performance × Provisioned IOPS × Billing duration = 0.000006 × 200 × 24 = USD 0.0288.

    • Burst performance fee: min((Number of burst I/Os - 100,000) × Unit price of performance bursts, Disk capacity fee × 8) = min((140,000 - 100,000) × 0.0015/10,000, 0.000319 × 100 × 8) = USD 0.006.

    • Total fee: Baseline performance fee + Provisioned performance fee + Burst performance fee = 0.7656 + 0.0288 + 0.006 = USD 0.8004.
