A. B. C. D.A.
The Cisco All-Flash HyperFlex solution is a hyperconverged infrastructure that integrates computing, storage, and networking in a single system. The operating system and persistent logging require local storage, and the local storage configuration needed depends on the specific deployment.
Option A, one solid-state drive, is a possible configuration for the local storage. Solid-state drives (SSDs) are faster and more reliable than traditional hard disk drives (HDDs), and they are a popular choice for storage in modern data centers. Using a single SSD can simplify the storage configuration, but it may not provide enough capacity or redundancy for larger deployments.
Option B, two SATA drives, is another possible configuration for the local storage. SATA drives are a type of HDD that use a serial ATA interface to connect to the system. Using two SATA drives can provide redundancy and fault tolerance, as data can be mirrored between the two drives. However, SATA drives are slower and less reliable than SSDs, which may impact performance and availability.
Option C, one SATA drive, is a less common configuration for local storage. Using a single SATA drive can be risky, as it provides no redundancy or fault tolerance. If the drive fails, the operating system and persistent logging data will be lost, which can lead to downtime and data loss.
Option D, two solid-state drives, is another possible configuration for the local storage. Using two SSDs can provide both performance and redundancy, as data can be mirrored between the two drives. This configuration can be more expensive than the other options, but it can provide the best balance of performance, capacity, and fault tolerance.
In summary, the best local storage configuration for the operating system and persistent logging in a Cisco All-Flash HyperFlex solution depends on the specific deployment requirements. Option A, one solid-state drive, may be sufficient for smaller deployments, while Option D, two solid-state drives, may be necessary for larger deployments that require high performance and fault tolerance. Options B and C may be less ideal due to their lower performance and/or lack of redundancy.
