Difficulty: HardBlob, File, and Disk Storage Solutions

A media production company is migrating its rendering and asset management platform to Azure. The platform consists of Linux-based virtual machines (VMs) and has the following requirements:

* A shared file storage volume that supports the NFS v 4.14.1 protocol and POSIX-compliant file locking.
* A database transaction log volume that must support at least 12,00012,000 IOPS and sub-millisecond write latency.
* Both the shared file storage and the database transaction log volume must be resilient to a primary datacenter outage within the Azure region.

Which combination of Azure storage solutions should you recommend to meet these requirements?

  1. A
    Standard Azure Files configured with NFS v4.1 and ZRS for the shared file storage, and a Premium SSD disk configured with LRS for the transaction log.
  2. B
    Premium Azure Files configured with SMB v3.0 and ZRS for the shared file storage, and a Standard SSD disk configured with ZRS for the transaction log.
  3. Premium Azure Files configured with NFS v4.1 and ZRS for the shared file storage, and a Premium SSD v2 disk configured with ZRS for the transaction log.Answer
  4. D
    Azure NetApp Files configured with NFS v4.1 for the shared file storage, and an Ultra Disk configured with ZRS for the transaction log.

Answer

Premium Azure Files configured with NFS v4.1 and ZRS for the shared file storage, and a Premium SSD v2 disk configured with ZRS for the transaction log.
Premium Azure Files supports the NFS v 4.14.1 protocol, POSIX locking, and Zone-Redundant Storage (ZRS). Premium SSD v 22 supports ZRS, provides sub-millisecond write latency, and allows provisioning 12,00012,000 IOPS independently of disk size, meeting all performance and resiliency requirements.

Step-by-Step Solution

1
Determine the requirements for the shared file storage volume.
The volume requires the NFS v 4.14.1 protocol, POSIX-compliant locking, and ZRS to survive a datacenter outage.
Only Premium Azure Files supports NFS v 4.14.1 in Azure Files. Standard Azure Files does not support NFS. Zone-Redundant Storage (ZRS) is required to survive a primary datacenter outage.
2
Determine the requirements for the database transaction log volume.
The volume requires at least 12,00012,000 IOPS, sub-millisecond write latency, and ZRS to survive a datacenter outage.
Premium SSD v 22 supports both ZRS and sub-millisecond write latencies while allowing independent provisioning of IOPS (up to 80,00080,000 IOPS). Standard SSD cannot meet the performance requirements, and Ultra Disk does not support ZRS replication.
3
Combine the compliant solutions to select the correct storage configuration.
Premium Azure Files with NFS v 4.14.1 and ZRS, paired with Premium SSD v 22 with ZRS.
This combination is the only one that meets all performance, protocol, and availability requirements.

Key Concept

Azure Storage service selection based on protocol, performance, and regional redundancy capability.
