An architect need to create capacity sizing of FlashBlade to move data from a 6-year old EMC-Dell Isilon. The current Isilon solution consumes almost 1.3PB. There are three workloads:

- Warehouse application (40 TB, estimated compression ratio 2:1, IO size 8K)

- Images (20 TB, estimated compression ratio 1.0:1 average image size 1M)

- Log files (40 TB, estimated compression ratio 4:1, average file size 4k)

What is the required FlashBlade configuration?

A customer map application is built with a containerized micro-service infrastructure that runs on Windows and accesses storage using SMB.

Each container is stateless, but every end user interaction leaves a set of small text and image files. Each directory keeps all daily transaction files. A process exists to manage file life cycle and periodically delete a directory.

The customer notices that as the customer base grows, the background deletion process backlog also grows. Which FlashBlade technology should be used to resolve this issue?

A customer is adding snapshot policies so that some file systems can be tiered based on importance to the business.

- 1 file system with high priority

- 3 file systems with medium priority

- 2 file systems with low priority

How many snapshot policies does the customer need to protect all of their file systems?

A customer is standing up a new 30x17TB FlashBlade system.

The customer’s environment is as follows:

1. The upstream switches are located 50 feet away

2. The upstream switches have the required number of 100Gb/s interfaces.

3. The customer is conscious about data availability.

4. The customer requires the use of 4 LAGs

What is the minimum number of cables required?

A customer has a FlashBlade and wants to use it to store data for an application that runs on Linux. The FlashBlade has four Data VIPs and is connected with four 40Gbe links connected to the Top-of-Rack switch in a virtual port-channel with trunking enabled. The Linux host has a single 40Gbe NIC and is configured with a single mount point located at /mnt/appdata. nconnect is not enabled.

What is the maximum throughput the customer should expect when reading data from the mount point?

A customer practices agile development, and they are having performance issues with builds of the most actively developed software suite as they attempt additional concurrent builds. What is causing the issue?

What is the support speed of the out-of-bound management port?

A customer is using the FlashBlade as an image database backup/restore target. The dataset that they are backing up is 100TB. The customer has a 5-day snapshot retention policy, and an average of 50TB of data change from day to day.

Which factor will alter the physical datasize?

A customer wants to use and orchestration tool to manage the FlashBlade.

How should the customer create the API key?

The customer has legacy production application that uses a hard-coded S3 access key with an encrypted hash for the secret key. The customer wants to enable development access to the production S3 bucket using the same S3 user account with a 60-day key rotation.

What should the architect do?
