The storage system adopts IP failover technology. If a physical host port that implements
the NAS protocol is damaged, the IP address assigned to that port automatically fails
over to another functional port. Based on the correct networking, services are seamlessly
failed over, preventing damage to a port from affecting services.
l
Online disk diagnosis
The online disk diagnosis feature is used to handle disk faults. If a disk fault occurs, the
storage system takes the disk offline. Then, the online diagnosis module reads the
S.M.A.R.T information about the disk and takes analysis, testing, and recovery
measures. After the disk is recovered, the online diagnosis module enables the disk to
rejoin the RAID, prolonging the lifecycle of the disk.
l
Data coffer disk
Data coffer disks consist of the first four disks of a storage system's controller enclosure
as well as the controller's two built-in disks. They store three types of data: cache data
requiring power failure protection, OceanStor OS system data, and system configuration
information and logs.
High Availability
In routine maintenance:
The OceanStor 2600 V3 storage system uses Turbo Module, online capacity expansion, and
disk roaming technologies to provide high availability for applications and nonstop system
running during maintenance.
l
Turbo Module enables controllers, fans, power modules, interface modules, and disks to
be hot-swappable, allowing online operations.
l
Dynamic capacity expansion enables users to add disks to a disk domain in an online and
easy manner.
l
Disk roaming enables a storage system to automatically identify relocated disks and
resume their services.
Cloud-based operation and maintenance (eService, also called as the Call Home service that is
applicable to V300R006C10 and later versions)
Huawei provides the eService service to remotely connect OceanStor 2600 V3 storage system
to the eService cloud platform, enabling centralized, remote, and intelligent operation and
maintenance of storage devices. The Big Data analytics technology is used to prevent faults
and locate faults quickly. In addition, it provides the optimal configuration, performance
optimization suggestions, and troubleshooting solutions based on user service characteristics.
In data protection:
The OceanStor 2600 V3 storage system provides the following advanced data protection
technologies and protocols to protect data integrity and continuous system running even when
catastrophic disasters happen:
l
Snapshot generates multiple point-in-time images for the source logical unit number
(LUN) or source file system data. The snapshot images can be used to recover data
quickly when needed.
l
LUN copy backs up data among heterogeneous storage systems for data protection.
l
Remote replication backs up local data onto a remote storage system for disaster
recovery.
