All rights reserved. — NETAPP CONFIDENTIAL — 5 RAID-4 (Row Parity) Utilizes block-level striping with a single, dedicated parity drive per RAID group Easier to expand RAID groups than RAID-5 Parity does not have to be recalculated and redistributed across all drives in the RAID group Protects against 1x drive failure or 1x uncorrectable media error ONTAP RAID Technologies 6 1 2 3 4 5 1 2 3 4 5 6 2 3 4 5 6 3 4 5 6 1 4 5 6 1 2 5 6 1 2 3 1 2 3 4 D5 D0 D1 D2 D3 D4 RP Row 1 2 3 4 5 DP

10. © 2024 NetApp, Inc. All rights reserved. — NETAPP CONFIDENTIAL — 9 RAID Triple Erasure Coding ( RAID-TEC) Extension of existing RAID DP architecture Additional licensing is not required Triple Erasure Coding adds a third parity disk to RAID DP groups Offers protection from up to three disk failures (any combination of media errors, failed disks etc.) in a RAID group Provides the ability to recover from a media error on a third disk in double degraded mode Performance is similar to RAID DP Uses an efficient XOR scheme which has minimal additional CPU/memory cost RAID reconstruction times for RAID-TEC are on par with RAID DP Increased maximum RAID group sizes All drive types supported: SSD & HDD but specifically targeted for SATA > 6TB Overview RAID Triple Erasure Coding

11. © 2024 NetApp, Inc. All rights reserved. — NETAPP CONFIDENTIAL — 10 Reduce exposure to data loss when deploying large capacity drives As drive sizes increase, longer rebuild times increase exposure to multiple drive failures New high-capacity drive types, such as cloud or archive, may have higher error rates and lower reliability specifications Growth in disk capacities and new drive types require enhanced RAID technologies to handle the increased risk of multiple drive failures for large capacity SATA > 6TB Increase flexibility of larger size RAID groups Efficient use of large capacity drives by supporting larger size RAID groups Ability to balance resiliency and performance Provides 100 times better protection against the risk of data loss resulting from multiple simultaneous drive failures in the same RAID group than RAID DP Resiliency Improvements for Large Capacity HDDs Why is RAID-TEC Needed?
