Storage issues in hospitals

Storage issues in hospitals 2

Outline of the issues

How to handle the issues?

Storage in hospitals:

Increase of management and cost

Storage issues in hospitals 3

Increased use of digital images

Higher number of images, including non-radiological

images

More sophisticated imaging techniques, higher resolution

images

Video

Storage for virtualisation techniques

Server Based Computing, e.g. VDI

Images of virtual servers

Increased demand of storage capacity

Regulations

Requirements for information security, NEN7510

Availability, confidentiality, integrity

Retention times

Technical reasons

Redundancy

Backup and restore

Disaster recovery

Storage techniques like deduplication and ‘thin

provisioning’

Increase of complexity

Storage issues in hospitals 5

Benchmark results

Relative increase of storage costs

28% of total infrastructure cost

Increase of cost, although

storage media gets cheaper

per TB

Increase of cost

Data Life Cycle Management

Which data has to be stored for what period?

How fast must data be available?

Difference between dynamic an static data

Storage tiering

Tiered storage architecture

Primary data on fast but expensive storage media

Infrequently accessed data moved to cheaper storage

media

Decrease the storage size

Deduplication, thin-provisioning

How to handle the issues?

Storage issues in hospitals 7

Storage as a managed service

On-premise or in a datacenter

Archive

Pay per TB (capex -> opex)

More predictable cost structure

Collective storage for different hospitals

Possible because of standardisation (DICOM, XDS)

Multi vendor support

Information exchange between hospitals

Insourced or outsourced
