“Just file it,” they say, and your obvious question is “where?” One of the new features introduced in PowerFlex 4.0 is file services. Which means that you can file it in PowerFlex. In this blog we’ll dig into the new file service capabilities offered with 4.0 and how they can benefit your organization.
I know that when I think of file services, I think back to the late 90s and early 2000s when most organizations had a Microsoft Windows NT box or two in the rack that provided a centralized location on the network for file storage. Often it was known as “cheap and deep storage,” because you bought the biggest cheapest drives you could to install in that server with RAID 5 protection. After all, most of the time it was user files that were being worked on and folks already had a copy saved to their desktop. The file share didn’t have to be fast or responsive, and the biggest concern of the day was using up all the space on those massive 146 GB drives!
That was then … today file services do so much more. They need to be responsive, reliable, and agile to handle not only the traditional shared files, but also the other things that are now stored on file shares.
The most common thing people think about is user data from VDI instances. All the files that make up a user’s desktop, from the background image to the documents, to the customization of folders, all these things and more are traditionally stored in a file share when using instant clones.
PowerFlex can also handle powerful, high performance workload scenarios such as image classification and training. This is because of the storage backend. It is possible to rapidly serve files to training nodes and other high performance processing systems. The storage calls can go to the first available storage node, reducing file recall times. This of course extends to other high speed file workloads as well.
Beyond rapid recall times, PowerFlex provides massive performance, with 6-nines of availability1, and native multi-pathing. This is a big deal for modern file workloads. With VDI alone you need all of these things. If your file storage system can’t deliver them, you could be looking at poor user experience or worse: users who can’t work. I know, that’s a scary thought and PowerFlex can help significantly lessen those fears.
In addition to the performance, you can manage the file servers in the same PowerFlex UI as the rest of your PowerFlex environment. This means there is no need to learn a new UI, or bounce all over to set up a CIFS share—it’s all at your fingertips. In the UI it’s as simple as changing the tab to go from block to file on many screens.
The PowerFlex file controllers (physical) host the software for the NAS servers (logical). You start with two file controllers and can grow to 16 file controllers. Having various sizes of file controllers allows you to customize performance to meet your environment’s needs. The NAS Servers are containerized logical segmentations that provide the file services to the clients, and you can have up to 512 in a cluster. They are responsible for namespaces, security policies, and serving file systems to the clients.
Each of the file volumes that are provided by the file services are backed by PowerFlex volumes. This means that you can increase file service performance and capacity by adding PowerFlex nodes to the storage layer just like a traditional block storage instance. This allows you to independently scale performance and capacity, based on your needs.
The following table provides some of the other specs you might be wondering about.
Feature | Max |
FS Capacity | 256 TB |
Max file size | 64 TB |
# of files | 10 billion |
# of ACLs | 4 million |
User File Systems | 4096 |
Snaps per File System | 126 |
CIFS | 160000 |
NFS exports | 80000 |
Beyond the architectural goodness, file storage is something that can be added later to a PowerFlex environment. Thus, you aren’t forced to get something now because you “might” need it later. You can implement it when that project starts or when you’re ready to migrate off that single use file server. You can also grow it as you need, by starting small and growing to a large deployment with hundreds of namespaces and thousands of file systems.
With PowerFlex when someone says “file it,” you’ll know you have the capacity to support that file and many more. PowerFlex file services provide the capability to deliver the power needed for even the most demanding file-based workloads like VDI and AI/ML data classification systems. It’s as easy managing the environment as it is integrated into the UI.

PowerFlex and CloudStack, an Amazing IaaS match!
Sat, 18 Nov 2023 14:13:00 -0000
|Read Time: 0 minutes
Have you heard about Apache CloudStack? Did you know it runs amazingly on Dell PowerFlex? And what does it all have to do with infrastructure as a service (IaaS)? Interested in learning more? If so, then you should probably keep reading!
The PowerFlex team and ShapeBlue have been collaborating to bring ease and simplicity to CloudStack on PowerFlex. They have been doing this for quite a while. As new versions are released, the teams work together to ensure it continues to be amazing for customers. The deep integration with PowerFlex makes it an ideal choice for organizations building CloudStack environments.
Both Dell and ShapeBlue are gearing up for the CloudStack Collaboration Conference (CCC) in Paris on November 23 and 24th. The CloudStack Collaboration Conference is the biggest get-together for the Apache CloudStack Community, bringing vendors, users, and developers to one place to discuss the future of open-source technologies, the benefits of CloudStack, new integrations, and capabilities.
CloudStack is open-source software designed to deploy and manage large networks of virtual machines as a highly available, highly scalable Infrastructure as a Service (IaaS) cloud computing platform. CloudStack is used by hundreds of service providers around the world to offer public cloud services and by many companies to provide an on-premises (private) cloud offering or as part of a hybrid cloud solution.
Users can manage their cloud with an easy to use Web interface, command line tools, and/or a full-featured RESTful API. In addition, CloudStack provides an API that is compatible with AWS EC2 and S3 for organizations that want to deploy hybrid clouds.
CloudStack can leverage the extensive PowerFlex REST APIs to enhance functionality. This facilitates streamlined provisioning, effective data management, robust snapshot management, comprehensive data protection, and seamless scalability, making the combination of PowerFlex storage and CloudStack a robust choice for modern IaaS environments.
You can see this in the following diagram. CloudStack and PowerFlex communicate with each other using APIs to coordinate operations for VMs. This makes it easier to administer larger environments, enabling organizations to have a true IaaS environment.

Let's talk about IaaS for a moment. It is a fantastic concept that can be compared with ordering off a menu at a restaurant. The restaurant has unrelated dishes on the menu until you start looking at their components. For example, you can get three different base sauces (red, pink, and white) with just a red sauce and a white sauce. With a small variety of pasta and proteins, the options are excellent. This is the same for IaaS. Have a few base options, sprinkle on some API know-how, and you get a fantastic menu to satisfy workload needs without having a detailed knowledge of the infrastructure.
That makes it easier for the IT organization to become more efficient and shift the focus toward aspirational initiatives. This is especially true when CloudStack and PowerFlex work together. The hungry IT consumers can get what they want with less IT interaction.
Other significant benefits that come from integrating CloudStack with PowerFlex include the following:
- Seamless Data Management: Efficient provision, backup, and data management across infrastructure, ensuring data integrity and accessibility.
- Enhanced Performance: Provides low-latency access to data, optimizing I/O, and reducing bottlenecks. This, in turn, leads to improved application and workload performance.
- Reliability and Data Availability: Benefit from advanced redundancy and failover mechanisms and data replication, reducing the risk of data loss and ensuring continuous service availability.
- Scalability: Scalable storage solutions allow organizations to expand their storage resources in tandem with their growing needs. This flexibility ensures that they can adapt to changing workloads and resource requirements.
- Simplified Management: Ability to use a single interface to handle provisioning, monitoring, troubleshooting, and streamlining administrative tasks.
- Enhanced Data Protection: Data protection features, such as snapshots, backups, and disaster recovery solutions. This ensures that an organization's data remains secure and can be quickly restored in case of unexpected incidents.
These are tremendous benefits for organizations, especially the data protection aspects. It is often said that it is no longer a question of if an organization will be impacted by an incident. It is a question of when they will be impacted. The IaaS capabilities of CloudStack and PowerFlex play a crucial role in protecting an organization's data. That protection can be automated as part of the IaaS design. That way, when a VM or VMs are requested, they can be assigned to a data protection policy as part of the creation process.
Simply put, that means that VM can be protected from the moment of creation. No more having to remember to add a VM to a backup, and no more "oh no" when someone realizes they forgot. That is amazing!
If you are at the CloudStack Collaboration Conference and are interested in discovering more, talk with Shashi and Florian. They will also present how CloudStack and PowerFlex create an outstanding IaaS solution.
Register for the CloudStack Collaboration Conference here to join virtually if you are unable to attend in person.

KubeCon NA23, Google Cloud Anthos on Dell PowerFlex and More
Sun, 05 Nov 2023 23:26:43 -0000
|Read Time: 0 minutes
KubeCon will be here before you know it. There are so many exciting things to see and do. While you are making your plans, be sure to add a few things that will make things easier for you at the conference and afterwards.
Before we get into those things, did you know that the Google Cloud team and the Dell PowerFlex team have been collaborating? Recently Dell and Google Cloud published a reference architecture: Google Cloud Anthos and GDC Virtual on Dell PowerFlex. This illustrates how both teams are working together to enable consistency between cloud and on premises environments like PowerFlex. You will see this collaboration at KubeCon this year.
On Tuesday at KubeCon, after breakfast and the keynote, you should make your way to the Solutions Showcase in Hall F on Level 3 of the West building. Once there, make your way over to the Google Cloud booth and visit with the team! They want your questions about PowerFlex and are eager to share with you how Google Distributed Cloud (GDC) Virtual with PowerFlex provides a powerful on-premises container solution.
Also, be sure to catch the lightning sessions in the Google Cloud booth. You’ll get to hear from Dell PowerFlex engineer, Praphul Krottapalli. He will be digging into leveraging GDC Virtual on PowerFlex. That’s not the big thing though, he’ll also be looking at running a Postgres database distributed across on-premises PowerFlex nodes using GDC Virtual. Beyond that, they will look at how to protect these containerized database workloads. They’ll show you how to use Dell PowerProtect Data Manager to create application consistent backups of a containerized Postgres database instance.
We all know backups are only good if you can restore them. So, Praphul will show you how to recover the Postgres database and have it running again in no time.
Application consistency is an important thing to keep in mind with backups. Would you rather have a database backup where someone had just pulled the plug on the database (crash consistent) or would you like the backup to be as though someone had gracefully shut down the system (application consistent)? For all kinds of reasons (time, cost, sanity), the latter is highly preferable!
We talk about this more in a blog that covers the demo environment we used for KubeCon.
This highlights Dell and Google’s joint commitment to modern apps by ensuring that they can be run everywhere and that organizations can easily develop and deploy modern workloads.
If you are at KubeCon and would like to learn more about how containers work on Dell solutions, be sure to stop by both the Dell and Google Cloud booths. If it’s after KubeCon, be sure to reach out to your Dell representative for more details.
