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?
The customer wants to build a software QA infrastructure using modern big data tools like Spark and Kafka. The goal is to process 50 billion events per day and provide feedback in real-time in less than 5 seconds.
The architect needs to create a FlashBlade configuration to meet the capacity and performance requirements using the following assumptions:
4 RSyslog servers accessing FlashBlade via NFS
6 servers accessing FlashBlade via S3
Capacity: 6TB + 18TB + 18TB
Each protocol will create a concurrent write and / or read throughput of 6GB/s
Which configuration should the architect use to meet these requirements?
A customer wants to use and orchestration tool to manage the FlashBlade.
How should the customer create the API key?
A FlashBlade is designed with a properly implemented single 4x40Gb/s LAG.
During implementation, the architect is informed that the ISL on the uplink switches in broken. The customer has no budget to repair or replace it. What should the architect do?
The customer is deploying FlashBlade on a ship with no immediate access to replacement part inventory. The customer needs at least 100TB of usable capacity at any time. The customer assumes worst case scenario in which FlashBlade can lose two blades between visting the next port where replacement can be shipped.
What is the recommend FlashBlade configuration?
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?
What is the speed of the connections between individual blades and the midplane?
