How would you calculate the size of the working set of storage that would live in a SSD/Flash tier of a tiered/hybrid storage solution? This would be used to gauge the size of the SSD/Flash tier.

By tiered/hybrid I mean something (e.g. a storage array) that presents storage that is made up of different tiers/types of disks such as SSD/Flash, SAS, NL-SAS etc. The 'something' then moves data around between the tiers of disk based on how active it is. More active data moves up to SSD/Flash and colder down to slower tiers.

With the recent problems that McAfee customers have had over the last week there has been lots of opinion that not only should the AV vendors have better testing but customers should test AV signatures before deploying.

Is this feasible? If you are doing this already do you take other measures to minimise exposure to malware while you are testing?

Update: With respect to feasible I mean is it feasible to run through a whole gamut of tests for each AV signature/definition update or do you restrict to just critical apps or critical functionality tests? Do you have a different approach for servers compared to desktops?

I would like to enable SMB2 on a FAS 2050 running Data ONTAP 7.3.2 as by default it is disabled.

I have discovered that to enable SMB2 the following option must be set:

options cifs.smb2.enable on

Does this require a restart of cifs to take affect or just does it start working magically? Also will this change persist across a reboot?

Update: As per James post below the following setting allows the filer to use SMB2 when talking to other servers.

options cifs.smb2.client.enable on
