Captures information from host(s) and filer(s)

Captures all information simultaneously for cross correlation

Operates on all host platforms and all filer platforms

All captured data is recorded in a single plain-text output file

 

Perfstat comes in exactly two flavors:

Unix/Linux version (perfstat.sh)

Windows version (perfstat.exe)

 

Supported platforms:

Unix: AIX, HP-UX, Linux, OSF1, Solaris, FreeBSD

Windows: 2000/XP/2003

Flash Cache is a controller-attached PCIe intelligent caching solution.

Flash Accel is a host-attached caching solution.

Flash Disk and Flash IO are ambiguous terms.

 

 

QUESTION 35

How can you “throttle” SnapValue updates and baseline transfers so that the primary or secondary is not transmitting data as it can?

 

A.

Use the -k option in the snapvault start or snapshot modify commands.

B.

SnapVault does not support throttling of network throughout.

C.

Use the snapvault throttle command.

D.

Use the -k option in the snapvault initialize command.

 

Correct Answer: D

Explanation:

http://backdrift.org/man/netapp/man1/na_snapvault.1.html

The snapvault subcommands are:

start [ -r ] [ -k n ] [ -t n ] [ -w ] [-p {inet | inet6 unspec}] [ -o options ] [ -S [primary_filer:]primary_path ] secondary_qtree modify [ -k n ] [ -t n ] [-p {inet | inet6 | unspec}] [ -o options ] [ -S primary_filer:primary_path ] sec_ondary_qtree

 

The -k option sets the maximum speed at which data is transferred in kilobytes per second. It is used tothrottle disk, CPU, and network usage. If this option is not set, the filer transmits data as fast as it can. Thesetting applies to the initial transfer as well as subsequent update transfers from the primary.

Correct Answer: C

Explanation:

https://communities.netapp.com/servlet/JiveServlet/previewBody/4791-102-2-13466/tr-3466.pdf

In order to restrict the NetApp secondary systems that are allowed to initiate backups from an OSSV host, theQSM Access List field can be populated with the hostname of the secondary using the OSSVConfigurator utility. When using this option, make sure the “Check QSM Access List” box is enabled.

The snapvault.access option on the NetApp secondary can be used to restrict the OSSV hosts that areallowed to initiate restores from that secondary system. This option can be populated with a list of hostnamesfor each OSSV host. For example:

options snapvault.access host=ossv1,ossv2,ossv3

Screenshot of the svconfigurator GUI; note the QSM access list checkbox and field.
