Soft allocation of X no. of blocks

Other snapshot (file-system retrofit?) NetApp SnapShots

SnapShot (things to test) Create a snap schedule with 28 snapshots

retain 10 hourly, 14 nightly, 4 weekly dump 20% new data on the volumes

○ resize the SnapReserve on the fly to add 15% more reserve delete 30% of the data and resize SnapReserve back to the

original delete 50% of the data, and run a SnapRestore

Try to hurt performance with sporadic Snapshot events Create 100 snapshots manually… what happens to

performance? Run plenty of create/change/modify operations, and create

another 100 snapshots Delete any odd number of snapshots What happens to performance, snapshot maintenance, and file-

system fragmentation?

Block Level ReplicationEven greater affect on Recovery and Resync

SnapMirror Highlights Things that are easy to test…

Robust incremental block replication ○ volume and qtree level○ dynamic bandwidth management○ resilient network congestion handling

Bi-directional Resynchronization○ break a mirror, update the DR side, bring the

new changes back to the original siteScalable and Flexible

○ Asynchronous over IP, semi-sync, and Full-Synchronous

○ IP or FC transports

RAID-DPDisruptive Approach Enabling ATA for Primary Storage

Industry: Mirroring NetApp: RAID-DP

– 4000X better protection

– <1% performance impact

– Comparable economics

RAID-DP Overview Description

Two parity drives per RAID group Extension of RAID 4 Standard feature

Primary Benefits >4,000X better protection <1% performance impact Comparable economic efficiency

Secondary Benefits Effortless conversion Lowers RAID reconstruction impact Seamless integration with NetApp SyncMirror™

Resilient StorageReconstruction vs. Rapid RAID Recovery

Reconstruction1. Read each block from each of the

remaining drives

2. Compute block for missing drive

3. Write block to spare

For example, a 8-drive RAID group of 144GB drives (136GB usable) requires data transfers of: 7 x 136 GB read plus 1 x 136 GB

writes = 1088 GB, and Computes parity for 2.44 x108 blocks!

Rapid RAID Recovery1. Copy the “sick disk” to a spare

2. Reconstruct the few blocks that cannot be read

For example, a 8-drive RAID group of 144GB drives (136 GB usable) requires data transfers of:

1x136 GB read plus 1x136 GB writes = 272 GB, and

Computes parity for just a few

blocks.
