Event Notifications; Time Services - IBM Storwize V7000 Unified Manual

v Optional public IP addresses for network attached storage (NAS) can be
assigned to allow external computer systems to access files and allow connection
with other NAS systems for services like asynchronous replication.
v The 1 Gbps Ethernet port 1 on each file module will be directly connected
together to allow the file modules cluster state to be kept in sync.
v The 1 Gbps Ethernet port 2 on each file module will be directly connected
together to allow the file modules cluster state to be kept in sync.
Optional 10 Gbps Ethernet ports and IP addresses
v Each file module has 2, 10 Gbps ports that can be connected to a 10 Gbps
Ethernet switch.
v Optional public IP addresses for network attached storage (NAS) can be
assigned to allow external computer systems to access files, and for connection
to other NAS systems for services like asynchronous replication over the 10
Gbps Ethernet.

Event notifications

Event notifications and call homes from the Storwize V7000 storage enclosures are
done by email. The IP address of an email server that can access the internet is
required.
Call home from a file module is done by electronic customer care (ecc) using
secure shell (SSH), and requires a proxy server to access the internet; or your
firewall must be made to allow each file module service IP address to ssh to the
IBM call home IP addresses (*.ibm.com) on the internet.

Time services

Access to a Network Time Protocol (NTP) server is required.
Authentication
An authentication directory service must be accessible through the 1 Gbps
Ethernet, providing network users access to file systems that have been shared
with network users. Alternatively, local authentication can be used, but this
method does not provide asynchronous file replication to another NAS system.
Important: The links to more information from installation error messages or from
the Storwize V7000 Unified critical events shown in the management GUI work
only if the web browser has internet access.
Best practice for performance
v The maximum work load should be less than 20 000 file operations per second.
Otherwise, ask your IBM Relationship Representative if the Storwize V7000
Unified system is the best product to meet your needs.
v File operations per second performance can be improved by configuring the
meta data for a file system into a storage pool that is provided by solid state
drives (SSD).
v The recommended minimum capacity allocation to a new file system is 100
gigabytes (GB).
v The total capacity of file systems should not exceed the capacity provided by
four Storwize V7000 storage enclosures.
