Elastic Desktop Service (EDS) provides computing resources for cloud computers that belong to the following type families: Office-based and Graphics Workstation-based. You can configure cloud computers with system disks and data disks of different capacities and performance levels (PLs) based on your business requirements. This topic describes computing resources and storage resources.
Background information
The cloud computer type in EDS refers to the specifications of computing resources and storage resources for cloud computers. The computing resources include vCPUs, memory, and GPUs. The storage resources include system disks and storage disks.
EDS provides different types of computing and storage resources for you to purchase based on your business requirements.

Storage specifications
By default, cloud computers of the Office-based type family use extreme SSDs, and cloud computers of the Graphics Workstation-based type family use enterprise SSDs (ESSDs).
Comparison of ESSDs at different PLs
ESSDs are cloud disks developed based on the next-generation distributed block storage architecture and provide ultra-high performance. ESSDs incorporate the 25 Gigabit Ethernet (GE) and remote direct memory access (RDMA) technologies. A single ESSD can provide up to 1,000,000 random read/write IOPS and reduced one-way latency. For more information, see ESSDs. The following table describes the comparison of ESSDs at different PLs.
ESSD attribute | Performance level | |||
PL3 | PL2 | PL1 | PL0 | |
Performance description | Ultra-high maximum concurrent I/O performance and ultra-low I/O latency | High maximum concurrent I/O performance and low I/O latency | Moderate maximum concurrent I/O performance and low I/O latency | Moderate maximum concurrent I/O performance and low I/O latency |
Capacity range (GiB) | 1,261~65,536 | 461~65,536 | 20~65,536 | 1~65,536 |
Data durability | 99.9999999% | 99.9999999% | 99.9999999% | 99.9999999% |
Maximum IOPS per disk | 1,000,000 | 100,000 | 50,000 | 10,000 |
Maximum throughput per disk (MB/s) | 4,000 | 750 | 350 | 180 |
Formula for calculating the IOPS per disk | min{1,800 + 50 × Capacity, 1,000,000} | min{1,800 + 50 × Capacity, 100,000} | min{1,800 + 50 × Capacity, 50,000} | min{1,800 + 12 × Capacity, 10,000} |
Formula for calculating the throughput per disk (MB/s) | min{120 + 0.5 × Capacity, 4,000} | min{120 + 0.5 × Capacity, 750} | min{120 + 0.5 × Capacity, 350} | min{100 + 0.25 × Capacity, 180} |
Example scenario | Large and medium-sized relational databases for core business and NoSQL databases, and large SAP and Oracle databases | Medium-sized relational databases and NoSQL databases, medium-sized Elasticsearch, Logstash, and Kibana (ELK) log clusters, and enterprise-level commercial software such as SAP and Oracle | Small and medium-sized MySQL and SQL Server databases, small and medium-sized ELK log clusters, enterprise-level commercial software such as SAP and Oracle, and container applications | Small and medium-sized MySQL and SQL Server databases, small and medium-sized ELK log clusters, enterprise-level commercial software such as SAP and Oracle, and container applications |
Recommended system or data disks to be replaced with ESSDs in recommended business scenarios | Data disks of instance families that are equipped with local SSDs and have 16 or more vCPUs (i1, i2, and i2g) | Standard SSDs and data disks of instance families that are equipped with local SSDs (i1, i2, and i2g) | Standard SSDs | System disks |
