A way to improve the Netapp storage performance?<\/strong><\/p>\n

There’s no direct declare this question however we have a tendency to shall love in many method.<\/p>\n

If volume\/lun gift in ATA\/SATA hard disk mixture, then the amount are often migrated to FC\/SAS disk mixture. Either you’ll be able to use flash cache to enhance performance.<\/p>\n

For NFS\/CIFS rather than accessing from single interface, multi mode vif are often organized to induce higher information measure and fault tolerance.<\/p>\n

Forever suggested to stay aggr\/vol utilization below ninetieth.<\/p>\n

Avoid doing multiple volume backup in single purpose of your time.<\/p>\n

Unable to map lun to solaris server, however solaris server aspect no issue. A way to resolve the issue?<\/strong><\/p>\n

FROM STORAGE SIDE:<\/p>\n

Verify iscsi\/fcp license is additional in storage<\/p>\n

Verify iscsi\/fcp session is logged in from server aspect use below command<\/p>\n

Netapp> igroup show -v<\/p>\n

Verify luns square measure mapped to the corresponding igroup<\/p>\n

Verify whether or not correct host kind is mentioned whereas making igroup and lun<\/p>\n

Verify whether or not correct iqn\/wwpn range is additional to igroup<\/p>\n

Verify partition is correctly organized from switch aspect, if it’s FCP protocol<\/p>\n\n\n\n
<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

\"NetApp<\/a><\/p>\n

A way to produce the LUN for UNIX server?<\/strong><\/p>\n

lun produce \u2013s size \u2013t UNIX \/vol\/vol1\/lunname<\/p>\n

A way to produce qtree and supply the security?<\/strong><\/p>\n

Netapp>qtree produce \/vol\/vol1\/qtreename<\/p>\n

Netapp>qtree security \/vol\/vol1\/qtree unix|ntfs|mixed<\/p>\n

A way to copy volume filer to filer?<\/strong><\/p>\n

ndmpcopy or snapmirror<\/p>\n

The way to size the aggregate?<\/strong><\/p>\n

Netapp> aggr add AggName no.of.disk<\/p>\n

The way to increase the volume?<\/strong><\/p>\n

ancient Volume<\/p>\n

vol add VolName no.of.disk<\/p>\n

Flexible Volume<\/p>\n

vol size VolName +60g<\/p>\n

What’s qtree?<\/strong><\/p>\n

qtree is Logical partition of the amount.<\/p>\n

What’s the default snap reserve in aggregate?<\/strong><\/p>\n

5%<\/p>\n

What’s snapshot? <\/strong><\/p>\n

A shot copy may be a read-only image of a standard or FlexVol volume, or AN combination, that captures the state of the filing system at some extent in time.<\/p>\n

What square measure the raid teams Netapp supporting?, what’s the distinction between them?<\/strong><\/p>\n

Supported RAID types:<\/p>\n

Raid-4<\/p>\n

Raid-6<\/p>\n

Raid-Dp<\/p>\n

What square measure the protocols you’re using?<\/strong><\/p>\n

Say some protocols like NFS, CIFS, ISCSI and FCP<\/p>\n

What’s the distinction between iscsi and fcp?<\/strong><\/p>\n

Iscsi-sending block through. iSCSI doesn’t needed dedicated network, it’ll work on existing network additionally. it work’s associate degree TCP\/IP.<\/p>\n

What’s the iscsi port number?<\/strong><\/p>\n

3260<\/p>\n

What’s the distinction between ndmp copy and vol copy?<\/strong><\/p>\n

Ndmp copy \u2013network information management protocol(used for tape backup)<\/p>\n

Vol copy \u2013 is employed to transfer volume to same or another mixture<\/p>\n

Justify however De-Duplication works?<\/strong><\/p>\n

In the context of disk storage, De-duplication refers to any rule that searches for duplicate knowledge objects (for example, blocks, chunks, files) and discards those duplicates. once duplicate knowledge is detected, it’s not maintained, however instead a \u201cdata pointer\u201d is changed in order that the storage system references a certain copy of the info object already keep on disk. This De-duplication feature works well with datasets that have countless duplicated date (for example, full backups).<\/p>\n

What’s the command wont to see quantity of house saved victimization De-duplication?<\/strong><\/p>\n

df \u2013s<\/p>\n

Command won\u2019t to check progress and standing of De-duplication?<\/strong><\/p>\n

sis status<\/p>\n\n\n\n
<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

However does one setup Snapvault shot schedule?<\/strong><\/p>\n

pri> snapvault snap sched vol1 sv_hourly 22@0-22<\/p>\n

This schedule is for the house directories volume vol1<\/p>\n

Creates hourly shot copies, except 11:00 p.m.<\/p>\n

Keeps nearly a full day of hourly copies<\/p>\n

What’s metadata? <\/strong><\/p>\n

Metadata is outlined as knowledge providing data concerning one or additional aspects of the info,<\/p>\n
