What is new inDOT 8.1

32-bit to 64-bit Aggregate Conversion

� Data ONTAP 8.1 supports 32-bit aggregate expansion– Data in-place – no data copying or migration

– Volumes online – reads, writes and other

operations continue

– Short, small performance impact –

it’s a background activity

26

How to trigger expansion to 64bit?

� aggr1 (size 13TB)– Admin decides to add 10 1TB disks

– Since the addition of the disks will cause the aggregate to go

over 16TB, the admin will be advised to run the following steps

� Trigger expansion

27

filer> aggr add aggr1 10Warning: By adding these disks, the aggregate's siz e will be too

large to revert to Data ONTAP 7.3. To proceed with this operation, and upgrade the agg regate from

32-bit format to 64-bit format, follow these steps: 1. Run the "aggr add" command with the "-64bit-upgr ade check"

option to determine whether there is enough free sp ace for the 64-bit upgrade

2. Resolve any space issues identified by the "-64b it-upgrade check" option

3. Run the "aggr add" command with the "-64bit-upgr ade normal" option to add the disks and trigger 64-bit upgrade on the aggregate

How to trigger expansion to 64bit?

� Add disks to trigger the expansion

28

filer> aggr add aggr1 -64bit-upgrade normal 10

Addition of 10 disks to the aggregate has completed.

The 64-bit upgrade scanner has started running on aggregate aggr1.

The 64-bit upgrade scanner has started running on volume vol1.

More Deduplication Updates

� License has been removed

� Deduplication performance is

higher in many cases

� Dedupe integration with Volume

SnapMirror is better

� Hourly checkpoints enable more

granular restart points

33

Data Compression Overview

� Generally available with Data ONTAP 8.1:

7-Mode and Cluster-Mode

� Space savings

– For data that doesn’t

deduplicate well, or

– In addition to what

deduplication can provide

34

Data Compression Overview continued

� Supported on 64-bit aggregates only

� No license required

� Data ONTAP 8.1 enhancements include

– Performance improvements

– No volume size limits

– New technical documentation

Other Items of Note

� 8.1 7-Mode supports IPv6 and SnapLock

� System Manager 2.0 is the device manager GUI

� Snapshot reserve default values have changed

– New volume reserve default is 5% (previously 20%)

– Aggregate reserve default is 0% unless SyncMirror is enabled

� Nondisruptive upgrade from Data ONTAP 7.3.2

File Systems and Partitions

� Aligning the partition aligns the file system

� File systems need to use a block size

that is an even multiple of 4096 bytes

– NTFS, EXT, VMFS

44

Partial I/O

� I/Os smaller than the physical block

� Generated by specific applications

– Database transaction logs

� May appear as unaligned I/O

� Not performance impacting

when sequential

45

Heuristic Checks (ONTAP)

� Data ONTAP counters

– lun show -v

– lun alignment show

– stats show lun

– nfsstat -d

� Partition table analysis

for susceptible

configurations

46

Alignment Heuristic on LUNs

� Automated calculations based on I/O patterns

� Reset internal counters – lun stats -z
