A wikipedia:disk array is a disk storage system which contains multiple disk drives (HDD or SDD). It is differentiated from a disk enclosure by providing additional functionalities and capabilities such as fault tolerant designs, cache memory, different RAID levels, deduplication, encryption and even virtualization.
Primary vendors of storage systems include
- Dell EMC
- Fujitsu
- Hewlett Packard Enterprise
- Hitachi Data Systems (HDS)
- Huawei
- IBM
- NetApp: NetApp FAS
- Oracle Corporation
Some disk arrays such as NetApp allows to group disks creating pools of HDD, SDD or mixed.
Activities[edit]
- Identify available vendors offering disk array solutions and their OS such as Netapp ONTAP
- Identify main advantages of using a disk array solution vs using computer internal disks or a internal array controller
- Identify main characteristics of disk arrays fault tolerant designs
- Identity hot plugging capabilities of disk arrays
- Understand different connectivity technologies such as Fibre Channel, NFS or iSCSI availables on disk arrays products.
