Table III.1 – Alignment analysis with functional requirements in [ITU-T Y.3513]

Functional requirements in [ITU-T Y.3513] Test objects in this Recommendation
26 7.2 Storage – It is recommended that the IaaS CSP – 8.6 Interoperability testing of
service provides storage functions, such as block storage life cycle management
functional level storage, file level storage and object- between the CSC and CSP
requirements based storage, with specific SLAs and
charging model to the CSC. The storage
functions can be provided to the CSC directly
or used by the virtual machine as attached
storage.

27 – It is recommended that the IaaS CSP – 8.6 Interoperability testing of
provides the CSC with operations handling storage life cycle management
mechanisms related to storage, such as between the CSC and CSP
create, attach, detach, query and delete a
volume of storage at either block level or
file-system level, write, read and delete data
for a given storage.

28 – It is recommended that the IaaS CSP – 8.7 Interoperability testing of
provides storage utilisation information in storage utilization status inquiring
response to queries from the CSC. between the CSC and CSP
29 7.2.1 Storage – It is recommended that the IaaS CSP – 8.1 Interoperability testing of
migration provides storage migration functions. Based storage migration between the CSC
on migration policies, data can be migrated and CSP
between different logical unit numbers
(LUNs), different storage devices, local
storage to shared storage and vice versa.
30 7.2.2 Storage – It is recommended that the IaaS CSP – 8.2 Interoperability testing of
snapshot provides storage with snapshot functions. storage snapshot between the CSC
Snapshot can be realized at either block or and CSP
file-system levels. The data can be restored
using the snapshot.
31 7.2.3 Storage – It is recommended that the IaaS CSP – 8.3 Interoperability testing of
backup provides storage with backup functions. storage backup between the CSC
Backup can be realized at block level, file and CSP
level or object-based storage.
32 7.2.4 I/O – It is recommended that the IaaS CSP – 8.5 Interoperability testing of I/O
performance provides input/output (I/O) limitation for performance between the CSC and
each VM. CSP
33 7.2.5 Storage – It is recommended that the IaaS CSP – 8.4 Interoperability testing of
resource provides storage resource (e.g., storage storage resource reservation
reservation space and LUN) reservation functions. between the CSC and CSP
34 7.3 Network – It is recommended that the IaaS CSP – 9.7 Interoperability testing of load
service provides network functions, such as IP balance between the CSC and CSP
functional address, VLAN, virtual switch, load balance, – 9.8 Interoperability testing of
requirements firewall, with specific SLAs or charging firewall between the CSC and CSP
model. Network functions are applied to
access and interconnect processing and
storage resources.

35 – It is recommended that the IaaS CSP – 9.10 Interoperability testing of
provides network information in response to network information inquiring
queries from the CSC. between the CSC and CSP
