Large-Memory ECSs
Overview
Large-memory ECSs provide an even larger amount of memory than memory-optimized ECSs. They are used for applications that require a large amount of memory, rapid data switching, low latency, and capability of processing large volumes of data. Large-memory ECSs provide large memory and high computing, storage, and network performance.

Notes
- Large-memory ECSs do not support NIC hot swapping.
- Specifications of large-memory ECSs can be modified only within the same flavor family.
- Affected by the memory loading speed, large-memory ECSs may take longer to start.
- Table 3 lists the OSs supported by large-memory ECSs.

- Large-memory ECSs can use ultra-high I/O EVS disks as the system disk and data disks.
- The primary and extension NICs of a large-memory ECS can only be used in the scenarios listed in Table 4.
- An ECS can have a maximum of 60 attached disks, including the system disk. For details about constraints, see Can I Attach Multiple Disks to an ECS?
For example, an E3 ECS can have one system disk and 59 data disks.
