Senior Network Engineer at Holy Redeemer Health System, Inc.

High performance and throughput enhance IT backup management

The multi-dimensional scale-out design feature of Pure Storage FlashBlade is not in use in our environment. Regarding data reduction technologies, we don't get much deduplication because the data is already deduplicated from our FlashArray before we get to backup, so there is no benefit of deduplication. Regarding the integration with cloud-native ecosystem tools, we are not on cloud; we are strictly an on-premises solution. Pure Storage FlashBlade is not used by any end-user; it's used only for IT backup, with only about four people in our group managing it. I cannot recommend Pure Storage FlashBlade to other users depending upon their financial situation because it's an expensive solution, and the cost is very high, including licensing and renewal every year. I rate Pure Storage FlashBlade an eight out of ten.

Auto-scaling capabilities enhance file management while reducing downtime

The most valuable feature of Amazon EFS is its auto-scaling capability. It's really easy to configure EFS by just creating it and running a command to directly configure it with my servers. It supports unlimited use, and charges are applied based on the file usage at the end of the month. The solution offers reduced downtime and increased durability through its auto-scaling features.

MuhammadAzhar Khan

Senior DevOps Engineer at Alibaba Group

Shared storage capabilities provide enterprise value with good reliability

Amazon FSx is more costly compared to other storage solutions like EBS or EFS. The auto-scaling feature should be improved, as it currently includes downtime. I need to manually increase the storage, which is not ideal. Integrating FSx with Windows Server is challenging; it's a long process involving Active Directory (AD) setup and synchronization.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."

More Pure Storage FlashBlade cons

"The main challenge with EFS is its cost, which is slightly higher compared to EBS or S3."

"It could be better in connecting with Windows Server instances."

"EFS could be improved by including a one-click setup."

"A direct FTP feature would be beneficial instead of relying on transmission services."

"From my experience, there are areas in Amazon FSx where more performance is needed, as they will be looking for higher IOPS."

"The price could be cheaper."

"The price is a little high."

"Our licensing is renewed annually."

"I understand that it is competitively priced compared to other brands."

"Pure Storage FlashBlade is a hardware appliance, and it's very expensive if you compare its price with other solutions. You can get the same features and benefits from its competitor, VAST Data, but for half the price of Pure Storage FlashBlade."

Overview

FlashBlade is the industry’s most advanced scale-out storage for unstructured data, powered by a modern, massively parallel architecture to consolidate complex data silos (like backup appliances and data lakes) and accelerate tomorrow’s discoveries and insights.

Pure Storage

Amazon Elastic File System (Amazon EFS) provides simple, scalable file storage for use with Amazon EC2 instances in the AWS Cloud. Amazon EFS is easy to use and offers a simple interface that allows you to create and configure file systems quickly and easily. With Amazon EFS, storage capacity is elastic, growing and shrinking automatically as you add and remove files, so your applications have the storage they need, when they need it.

When mounted to Amazon EC2 instances, an Amazon EFS file system provides a standard file system interface and file system access semantics, allowing you to seamlessly integrate Amazon EFS with your existing applications and tools. Multiple Amazon EC2 instances can access an Amazon EFS file system at the same time, allowing Amazon EFS to provide a common data source for workloads and applications running on more than one Amazon EC2 instance.

It’s designed for high availability and durability, and provides performance for a broad spectrum of workloads and applications, including Big Data and analytics, media processing workflows, content management, web serving, and home directories.

Amazon Web Services (AWS)

Amazon FSx makes it easy and cost effective to launch and run popular file systems. With Amazon FSx, you can leverage the rich feature sets and fast performance of widely-used open source and commercially-licensed file systems, while avoiding time-consuming administrative tasks like hardware provisioning, software configuration, patching, and backups. It provides cost-efficient capacity and high levels of reliability, and it integrates with other AWS services so that you can manage and use the file systems in cloud-native ways.

Amazon FSx provides you with two file systems to choose from: Amazon FSx for Windows File Server for enterprise workloads and Amazon FSx for Lustre for high-performance workloads.
