LDAP
|
Lightweight
Directory Access
Protocol
|
LDAP
is an Internet standard protocol used by applications to access information
in a directory.
It runs directly over TCP, and can be used to access a standalone LDAP directory service or to access a directory service.
LDAP
is a protocol defining a directory service and access to that service. LDAP
is based on a client-server model. LDAP servers provide the directory service,
and LDAP clients use the directory service to access entries and attributes.

SAN
|
Storage
Area
Network
|
A
SAN file system is programming that enables the sharing of the same copies of
files stored on common storage media among multiple servers that may have
different operating systems.
|
NAS
|
Network Attached Storage
|
A
NAS unit is a computer connected to a network that provides only file-based
data storage services to other devices on the network. Although it may
technically be possible to run other software on a NAS unit, it is not
designed to be a general purpose server. NAS systems contain one or more hard
disks, often arranged into logical, redundant storage containers or RAID
arrays.
|
DAS
|
Direct
Attached
Storage
|
DAS refers to a digital storage system directly attached to a
server or workstation, without a storage network in between, mainly used to
differentiate non-networked storage from SAN and NAS.
A
DAS device can be shared between multiple computers, as long as it provides
multiple interfaces (ports) that allow concurrent and direct access.
|
NAS Vs SAN
|
The difference between a NAS and a SAN is that NAS appears to
the client OS (operating system) as a file server (the client can map network
drives to shares on that server) whereas a disk available through a SAN still
appears to the client OS as a disk.

Hi, first time implementing HA PC 9.5.1 residing on Windows platform. We have NAS - EMC celerra NAS for File sharing also recomended file sharing for Widows platform. I dont know how to configure Binarys, Domain logs, INFA_HOME and INFA_SHARED fiel system from Node1 and Node2 points to NAS storage and both nodes are accessable to the storage device as per the pre- checklist doc. Appreciate inputs thanks.
ReplyDeleteEach node will be having it's own user/home and you will have to create. .profile file in each of the homes and add the environment variable in .profile file. Please make sure to run the profile file once you have added the entries.
