Multi-Service Isolation and Flexible Resource Allocation

Multi-Service Isolation

When multiple enterprise IT applications are run on the same hardware platform for lowered cost and easy maintenance, an effective service isolation mechanism is needed to ensure service stability, reliability, and security.

The OceanStor 2810 V5 storage system uses SmartContainer feature applications of multiple services.

• Mainstream operating systems and their applications can be deployed on different VMs for isolation.
• The operating systems and applications deployed on VMs are independent from each other, and VMs have their own storage resources. Services and applications are securely isolated.

Figure 3-1 shows a multi-service isolation scenario.

Flexible Resource Allocation

The virtual machine (VM) technology has become popular in many scenarios because it greatly improves application server utilization and lowers deployment costs and operation expenditure (OPEX) of services. However, as an increasing number of applications and virtual desktops are deployed in VMs, VM density naturally increases. High VM density indicates a significant increase (in some cases several orders of magnitude) in the amount of service data and data bandwidth than a single server would. This poses ever demanding requirements for storage capacity and performance.

Nowadays, it is a tendency for one storage system to process a diversified range of applications. However, those applications often have different storage requirements, so the storage system must be highly flexible in resource allocation.

The following lists the storage requirements of different types of server applications:

• Database server

  Processes structured data and requires high storage performance, data integrity, and system stability.

• Email server

  Processes a large number of random and concurrent accesses and requires high storage performance, data integrity, and system stability.

• Video server

  Stores a large amount of data and requires high storage performance, continuous data access, and continuous high bandwidth.

• Backup server

  Has low requirements on storage performance and bandwidth.

The OceanStor 2810 V5 storage system can allocate hardware resources such as different sizes of caches, and CPU resources to VMs carrying different applications. You can customize hardware configurations based on service and storage performance requirements.
