SAN. See storage area network (SAN).
scheduled report. A report that comes out at a predetermined time.
scorecard grid. A system used to mark areas to be replicated when a disrupted network is later restored.
Secure Sockets Layer (SSL). A cryptographic protocol that provides communication security over the Internet. It
encrypts the segments of network connections above the Transport Layer, using asymmetric cryptography for privacy
and a keyed message authentication code for message reliability. Several versions of the protocol are in widespread
use in applications such as web browsing, electronic mail, Internet faxing, instant messaging and voice-over-IP (VoIP).
The same can be said of it's successor protocol, Transport Layer Security (TLS).
security. The rules that allow and limit access to computers and data. In IBM SmartCloud VSR, security is based on
assigned roles and the IBM BCRS Firewall, providing security and isolation between the customer network and the
IBM BCRS Core LAN.
Self-Service Portal. A, portal, web portal or self-service portal is a web site that functions as a point of access to
information on the Internet. A portal presents information from diverse sources in a unified way. See portal. See also
web portal.
service level. IBM SmartCloud VSR offers three levels of service, as follows:
v See Reserved Resource Virtual Machine service level.
v See Shared Resource Virtual Machine service level.
v See Imported Media Virtual Machine service level.
Shared Resource Virtual Machine service level. The mid-range service level offering of the VSR product. The
typical recovery time objective (RTO) for this service level is less than 15 minutes. VSR takes snapshots of the target
system at this service level hourly.
In other respects it is identical to the Reserved Resource Virtual Machine service level, the notable exception being the v
service feature, itself. VSR takes snapshots of the target system at the Reserved Resource Virtual Machine service level
every fifteen minutes.
This is the only service level upgradeable to the Reserved Resource Virtual Machine service level. The silver server icon
in the tree view indicates a server protected at the Shared Resource Virtual Machine service level.
silver-Level server recovery. See Shared Resource Virtual Machine service level.
SMOS. See SnapMirror for Open Systems (SMOS).
SnapMirror for Open Systems (SMOS). Enterprise-class software for data replication and recovery across
heterogeneous infrastructure.
snapshot. The state of a system at a particular point in time. The Shared Resource Virtual Machine service level stores
24 snapshots (taken hourly), while the Reserved Resource Virtual Machine service level stores 96 (taken each quarter
hour).
SocketException. A SocketException is thrown by the Socket and Dns classes when a network error occurs.
Splash Screen. An image that appears while a program is loading.
SSL. See Secure Sockets Layer (SSL).
SSL certificate. The Secure Socket Layer protocol was created to ensure secure transactions between web servers
and browsers. The protocol uses a third party, a Certificate Authority (CA), to identify one or both ends of the
transactions.
storage area network (SAN). A dedicated network that provides access to consolidated, block level data storage.
Structured Query Language (SQL). An international standard language for manipulating relational databases.
suspend replication. Suspending replication allows you to stop replication system operation for maintenance or
troubleshooting, without termination.
