Answer : A, B

iSCSI Multipathing: Enables multiple paths for data to travel between the host and storage, providing redundancy and increased performance.

Steps to Enable:

iSCSI IP Setup: Configure IP addresses for the iSCSI interfaces on both the E-Series system and the Windows host to ensure proper network communication.

Host Utilities: Install NetApp E-Series Host Utilities on the Windows host to provide the necessary drivers and multipathing software.

Answer : C

EF570 Systems: The EF570 supports multiple host protocols simultaneously, including NVMe.

Connection Issue: The controller on-board ports not connecting while HIC ports are working fine suggests a potential configuration issue.

SFP Mismatch: The most likely cause is that the on-board ports have the wrong Small Form-factor Pluggable (SFP) modules installed for NVMe protocol.

Solution: Ensure that the correct SFPs for NVMe protocol are installed in the on-board ports.

Answer : A

RAID Levels Overview:

RAID 5: Single parity, moderate overhead.

RAID 6: Dual parity, higher overhead than RAID 5.

RAID 10: Mirroring and striping, highest overhead due to 100% redundancy (mirroring).

Dynamic Disk Pools (DDP): Efficient use of capacity but more overhead than RAID 5.

Overhead Calculation:

RAID 10 has the most overhead because it mirrors all data, effectively using twice the storage capacity.

Capacity Overhead: The overhead in RAID 10 is 50% of the total capacity, meaning if you have 1 TB of usable storage, you need 2 TB of total storage.

Answer : C

Understanding the Requirements: The administrator needs to provision a 1 TB volume for non-critical temporary data that requires the highest possible IOPS.

Non-Critical Data: Since the data is non-critical, redundancy (data protection) is not the primary concern. Therefore, RAID 0, which does not provide redundancy but maximizes performance, is suitable.

Highest Possible IOPS: RAID 0 is known for providing the highest IOPS compared to other RAID levels because it stripes data across multiple disks, allowing simultaneous read/write operations.

Segment Size: A smaller segment size (32 KiB) will result in higher IOPS for small random I/O operations, which is typical in seismic-analysis applications.

Answer : B

Dual-purpose SFPs: These are transceivers capable of supporting multiple data rates, allowing for flexible deployment in different networking environments.

Supported Data Rates: In the scenario where you are reviewing the storage array profile to determine if dual-purpose SFPs are installed, a set of supported data rates of 32 Gbps, 16 Gbps, 8 Gbps, and 4 Gbps indicates the presence of such SFPs. This enables the switch from iSCSI to FC without needing to replace the hardware.

Configuration: Once the correct SFPs are identified, the host protocol can be adjusted accordingly within the SANtricity System Manager to utilize the desired Fibre Channel speeds.
