Scale-out: Add more servers to do the workload

Scale-up: Add more resources (such as processors and memory) to existing servers

Scale-out: Add an additional two-socket system to an existing VMware Cluster

Scale-up: Add two additional processors to a four-socket system currently equipped with only two processors

This is because:

Scale-out: This is a scaling approach that involves adding more servers or nodes to a system to increase its capacity and performance. It is also known as horizontal scaling. It can help distribute the workload across multiple servers and improve availability and fault tolerance.

Scale-up: This is a scaling approach that involves adding more resources (such as processors, memory, storage or network) to an existing server or node to increase its capacity and performance. It is also known as vertical scaling. It can help improve the performance of a single server and reduce the complexity of managing multiple servers.

RAID 1: any single drive

RAID 1 ADM: any two drives

RAID 5: any single drive

RAID 6: any two drives

RAID 1: This is a level of RAID that uses mirroring to create an exact copy of data on two or more disks. It can tolerate the failure of any single drive without losing data, as long as the other drive is still functional.

RAID 1 ADM: This is a level of RAID that uses advanced data mirroring to create two copies of data on three disks. It can tolerate the failure of any two drives without losing data, as long as the third drive is still functional.

RAID 5: This is a level of RAID that uses striping with parity to distribute data and parity information across three or more disks. It can tolerate the failure of any single drive without losing data, as long as the other drives can reconstruct the data from the parity information.

RAID 6: This is a level of RAID that uses striping with double parity to distribute data and two sets of parity information across four or more disks. It can tolerate the failure of any two drives without losing data, as long as the other drives can reconstruct the data from the double parity information.

ï‚· RAID 60 with two parity groups: Capacity of four drives

ï‚· RAID 50 with two parity groups: Capacity of four drives

ï‚· RAID 10 with four drives: Capacity of two drives

ï‚· RAID 1 ADM with three drives: Capacity of two drives

ï‚· RAID 60 with two parity groups:

RAID 60 is a combination of RAID 6 and RAID 0. It uses double parity (RAID 6) for fault tolerance and striping (RAID 0) for performance.

With two parity groups, it means there are two sets of RAID 6 arrays, and each set needs two parity drives.

Therefore, the capacity overhead would be the equivalent of four drives used for parity.

ï‚· RAID 50 with two parity groups:

RAID 50 is a combination of RAID 5 and RAID 0. It uses single parity (RAID 5) for fault tolerance and striping (RAID 0) for performance.

With two parity groups, it means there are two sets of RAID 5 arrays, and each set needs one parity drive.

Therefore, the capacity overhead would be the equivalent of two drives, but considering both groups, it would be four drives.

ï‚· RAID 10 with four drives:

RAID 10 is a combination of RAID 1 and RAID 0. It mirrors data (RAID 1) and stripes it (RAID 0).

For four drives, RAID 10 effectively uses two drives for data and two drives for mirrored copies.

Therefore, the capacity overhead is the equivalent of two drives.

ï‚· RAID 1 ADM with three drives:

RAID 1 ADM (Advanced Data Mirroring) typically involves three drives where each piece of data is mirrored across all three drives.

Thus, the capacity overhead is the equivalent of two drives being used for mirroring.

This is because single-mode fiber optic cable has a small core diameter that allows only one mode of light to propagate. This reduces signal attenuation and enables longer transmission distances than multimode fiber optic cable, which has a larger core diameter that allows multiple modes of light to propagate. Single-mode fiber optic cable can support distances up to 40 kilometers for Fibre Channel applications.

ï‚· Understanding the Concept:

The "Buffer" in HPE GreenLake refers to additional capacity provided within the as-a-service model.

ï‚· Buffer Options:

A. Capacity for Management and Logs: While necessary, this is not specifically referred to as the "Buffer."

B. Reserved Capacity for Failure: Critical but not the primary purpose of the "Buffer" in the GreenLake context.

C. Capacity Available for Consumption: This aligns with the "Buffer" concept in GreenLake, where extra capacity is pre-installed and can be used as demand increases.

D. Reserved for Upgrades and Updates: Not specifically referred to as the "Buffer."

ï‚· Why C is the Correct Answer:

On-Demand Availability: The buffer capacity is pre-installed and immediately available, allowing customers to scale quickly without waiting for additional infrastructure to be provisioned.

Flexibility: It ensures that there is always enough capacity to handle unexpected increases in demand.

NAS: c) Sharing files over industry standard protocols such as NFSv4 or SMB.

SAN: a) Block access using a FC protocol. or b) Block access using FCoE protocol or d) Block access using the iSCSI protocol.

According to the HPE website, NAS stands for Network Attached Storage and is a storage system that provides file-level access to data over a network. NAS devices use protocols such as NFSv4 or SMB to share files with clients. NAS devices typically have their own file system and operating system and can support multiple users and applications.

SAN stands for Storage Area Network and is a network that provides block-level access to data over a dedicated network. SAN devices use protocols such as FC, FCoE, or iSCSI to transfer blocks of data to servers. SAN devices do not have their own file system and rely on the servers to manage the data. SAN devices typically provide high performance and availability for mission-critical applications.

iLO Enablement Kit: The HPE ProLiant MicroServer Gen10 Plus does not come with integrated Lights-Out (iLO) functionality by default. To enable remote management capabilities, you need to install the iLO Enablement Kit, which provides the necessary hardware and licenses for iLO functionality.

HPE workload profile is one of the HPE Intelligent System Tuning (IST) features and allows you to tune the resources in your HPE ProLiant server by choosing a preconfigured workload profile. The server will automatically configure the BIOS settings to match the selected workload12.

According to the information I found on the web, here is how you can match the preconfigured HPE workload profile with its definition:

General power efficient compute: This is a default out-of-the-box profile that uses the most common performance settings seen across most application workloads. It also enables power management settings that have minimal impact to overall performance. This profile is recommended for customers that do not typically tune their BIOS for their workload1.

IO throughput: This profile is intended for configurations that depend on maximum throughput between IO and memory. It disables power management settings that are known to have impact on maximum achievable bandwidth. It also applies settings that benefit NUMA awareness, as best throughput is achieved when the workload is also NUMA aware and optimized1.

Graphics processing: This profile is intended for configurations that use GPUs and depend on maximum bandwidth between IO and memory. It disables power management settings that are known to have impact on maximum achievable bandwidth. It also applies settings that benefit NUMA awareness, as best throughput is achieved when the workload is also NUMA aware and optimized1.

Virtualization —Max Performance: This profile setting will ensure that all available virtualization technologies are enabled and configured for maximum performance. It disables power management settings in favor of delivering maximum performance. Certain virtualization technologies can have possible performance impacts to nonvirtualized environments and can be disabled in other profiles
