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.

Explanation:

The exhibit shows the supported adapter cards for the E2812 system with specific marketing part numbers.

The E2812 system ordered is a Duplex 16Gb 10GbE Base-T system with the adapter card part number X-56023-00-0E-C, which is described as "HIC.E2800.10Gb Base-T.2-ports, -C".

Each card provides 2 ports.

Given that the system is duplex, it means it has two controllers, each capable of supporting one card.

Therefore, each controller can have one 10GbE Base-T card with 2 ports, resulting in a maximum of 4 ports available in total for the system.

Fabric attachFC topology is the most scalable host-side connection topology for E-Series systems.

This topology involves connecting the E-Series storage system to a Fibre Channel switch, which then connects to the hosts.

Scalability: The fabric attach topology supports a large number of devices by allowing multiple switches to be interconnected, forming a fabric.

Redundancy: It offers higher redundancy and failover capabilities because multiple paths can be created between the hosts and the storage.

Verify that the E2812 host port SAS link up lights are illuminated

Explanation: The link up lights on the E2812 host port should be checked to confirm that the physical layer connection is established. If the lights are not illuminated, it indicates that there is no physical link between the host and the E2812 system, which would explain why the host cannot access the volumes.

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.

To resolve the issue of a new Windows host being unable to connect to a volume on the E-Series system when all other hosts can, follow these steps:

Obtain the WWPN for the Windows HBA (B):The Worldwide Port Name (WWPN) is essential for zoning and establishing communication between the host and the storage system. Ensure you have the correct WWPN for the new Windows host’s HBA.

Create a single-initiator zone with the host and E-Series system (D):Zoning is crucial in SAN environments to control and secure the data paths. Create a single-initiator zone that includes the WWPN of the Windows host and the target ports of the E-Series system. This ensures that the host can see the storage.

Add a zone to the active zoneset (E):After creating the necessary zone, it needs to be added to the active zoneset on the Cisco MDS switch. The zoneset must then be activated for the changes to take effect, enabling the new host to communicate with the E-Series system.

These steps ensure that the new Windows host is properly zoned and can access the storage volumes without disrupting the existing configurations.

Explanation: To support multiple mirroring relationships, each with different recovery point objectives (RPOs), the administrator should create multiple mirror pairs. Each pair can be configured with its own schedule and RPO, allowing for tailored data protection strategies that meet specific needs.
