Why Scale

Why Scale--Out NAS Storage?

Out NAS Storage?

Scale-Out NAS

• Provides integration and management of data over Petabytes

• Reducing TCO

• Cloud storage on all kinds of business data types, automated and integrated hierarchical storage and information lifecycle management

• Billions of files are supported by self managed and automated policy based tiered storage

• Provides capacity expansion, fastest search, backup/restore, expandability, modular design, availability and flexibility

• Supports intellectual load-balancing and dynamic thin-provisioning

• Starts from small but expandable when business requirement changes

Many enterprises require high-performance storage solutions which can process non-linear high-capacity data like multimedia, digital contents increased geometrically and huge number of files created by applications.

• Every SCALEWAY nodes can access storage volumes

• Clients can access storage volumes through all SCALEWAY nodes

• SCALEWAY node can be extended to over 1,000 nodes and all nodes are working as active

• In case of SCALEWAY node failure, the I/O is maintained via other SCALEWAY node by automatic fail-over, and uninterrupted increase or decrease SCALEWAY nodes and storages.

• By the client’s requirements, SCALEWAY nodes can make performance higher and bottlenecks can be solved fundamentally

Automatic Fail Over

/Data /Data

• When node or network fails, SCALEWAY handles I/O separately via other live nodes • In failure situation, SCALEWAY stores shared storage using other nodes automatically

• Storage can be expanded, regardless of storage vendors

• FC, SAS, SATA storage can be applied differently for the work depends

(12)

Thin Provisioning

• Disk configuration necessary capacity only on on-line status (not required total

capacity on initial installation)

• Volume decrease on on-line status by removing unnecessary disks

– File system reconfiguration is based on striping (can only on expanding volume space) – No data corruption and configured automatically or manually

Storage Policy (ILM)

Based on user’s data operation policy, storage

configuration inside single file system can be possible

§ Separating storage pools (FC, SAS and

SATA disks) to maximize operation efficiently for purposes

§ During operation of several pools, data

moving between pools by policy adaption can be possible

§ Storage pooling can be possible by

dividing storage classes into hierarchical structure Storage Network Tape System Enterprise: Priority Data Area
