Zorluk: OrtaBlob, File, and Disk Storage Solutions

An organization is designing a shared storage solution for a Linux-based high-performance computing (HPC) cluster deployed on Azure Virtual Machines. The application running on the cluster requires a shared file system that supports POSIX-compliant file permissions and the NFS v4.1 protocol. The shared storage must also be able to survive a primary datacenter outage within the region. Which two configuration options should you recommend to meet these requirements? (Select TWO.)

  1. A storage account type of FileStorageCevap
  2. A redundancy configuration of Zone-Redundant Storage (ZRS)Cevap
  3. C
    A storage account type of General Purpose v2 (GPv2)
  4. D
    A redundancy configuration of Locally Redundant Storage (LRS)
  5. E
    A Shared Access Signature (SAS) token with a validity period of 12 months to authenticate client connections

Cevap

To meet the requirements, you must recommend a storage account type of FileStorage and a redundancy configuration of Zone-Redundant Storage (ZRS).
The design must support NFS v4.1 and survive a primary datacenter outage. NFS v4.1 is only supported on Premium Azure Files, which must be deployed in a FileStorage storage account. To achieve zone-level resiliency against a single datacenter failure, Zone-Redundant Storage (ZRS) must be used as the redundancy option.

Adım Adım Çözüm

1
Determine the storage account type required for the specified protocol.
The requirement for NFS v4.1 protocol support on Azure Files dictates using Premium tier file shares. Premium file shares can only be created within a FileStorage account.
General Purpose v2 (GPv2) accounts support standard file shares, which are limited to SMB protocol access.
2
Select the redundancy option capable of surviving a single datacenter outage.
Choose Zone-Redundant Storage (ZRS) to replicate data across three Azure availability zones in the region.
Locally Redundant Storage (LRS) only replicates data within a single datacenter and would fail if that datacenter experienced an outage.
