Hi,

I’m Rick Braddy, Founder, CEO and CTO of SoftNAS®. Like you, I have been in the situation where I was dependent upon Storage-as-a-Service and forced to live with slow performance, and with no control or say in how that NFS storage was structured or delivered. In my case, it was on-premise on VMware® using NFS-mounted multi-user, shared Isilon® storage arrays in a private cloud, where we could not install our own storage appliances. We were stuck and ended up having to switch data centers to resolve this storage performance issue that plagued our business. It’s very frustrating when the users complain about slow application performance, then the bosses get riled up, and there’s little to nothing you can do about it. So I feel your pain…

Today customers have choices, along with the freedom to choose. So if you’re experiencing slow or inconsistent performance with your current storage provider (EFS or other) and need answers, you came to the right place. If you haven’t yet deployed and are evaluating your options, this is a great time to get the facts, before you find yourself stuck and have to switch horses later, as we see all too often.

We commonly see AWS customers who have tried EFS (and other options) that have hit slow performance, high costs and other barriers that do not meet their business requirements. But it’s not just throttling from burst limits that slows performance. It’s the very nature of shared, multi-tenant filesystems that makes them prone to bottlenecks, as shown in the following animated image.

A shared, multi-tenant filesystem must deal with millions of concurrent filesystem requests coming from thousands of other companies, who compete for filesystem resources within a Shared Data Service Lane. It’s easy to see why performance becomes slow and unpredictable in a shared, multi-tenant filesystem that must service so many competing requests. In such an environment, bottlenecks and collisions at the network and storage levels are unavoidable at times.

Contrast that with having a Dedicated Data Express Lane like SoftNAS Cloud®, your own exclusive Cloud NAS with its caching and resources focused on your data alone, where your applications’ needs are met consistently and always at maximum performance.

Below we see the published EFS burst limits. As applications use more throughput, burst credits are used. Applications that use too much I/O are penalized and EFS throttles performance, one of the potential causes for slow EFS performance.

EFS is a shared, multi-tenant filesystem, subject to burst limits and multi-tenant bottlenecks. SoftNAS is a dedicated, high-performance filesystem with no burst limits and access to full EBS performance, regardless of how much storage capacity you use. This is the first core difference between the two – shared vs. dedicated infrastructure.

Clearly, there’s a place in the market where each type of filesystem fits and serves its respective purpose. The question is, which approach best meets your application and business needs?

Performance results can also vary based upon many other factors and each application’s unique behavior. Therefore, we recommend customers run benchmarks and test their applications at scale with simulated user loads, before finalizing the components that will be placed into production as part of their cloud stack. This is often best accomplished during a proof-of-concept stage before applications go into production. Unfortunately, all too often customers discover too late in the process that they have performance issues and are in urgent need of a solution…

Since 2013, SoftNAS has provided thousands of customers with high-performance, dedicated Cloud NAS solutions. In fact, we originally pioneered the “cloud NAS” category as the #1 Best-selling NAS in the Cloud. By coupling industry-standards like ZFS on Linux with our patented cross-zone high-availability and high-performance EBS and S3-backed storage technologies, SoftNAS has consistently provided customers with the most flexibility, choice and value for business-critical NFS and CIFS with Active Directory for AWS®.

What do customers say about EFS? EFS has been in the marketplace for several years now, so there’s been plenty of time to hear from customers about their experiences. It’s helpful to consider what customers see and report.  Here’s some examples of comments our Support Team sees below. You can search for “EFS slow” to do your own research.

“We want to migrate about 5 percent of our 150+ Centos based servers from on-prem to AWS and need NFS and CIFS but AWS does not offer EFS in Canada.”
“Hi we were suggested to contact you guys from our AWS rep in helping us deal with the issues EFS has due to the slowness of I/O … our AMI’s currently mount our EFS mount point and due to the nature of the software we are using it tends to use a lot of file_get_contents, is_dir functionality which is very slow with EFS compared to a standalone server with SSD. Is this something you guys can help us with and get it up and running in our VPC?”
“We host multiple Magento based websites for our clients in AWS and looking for a solution that we can use to replace AWS EFS as it is very slow with many small files and it is not yet available in many regions.”
“I am trying the trial of SoftNAS in our AWS cloud for potential use for SMB/CIFS & NFS to be used as a replacement for EFS. We have reached the limit of the capabilities of EFS and so looking into other products.”
“I need a demo by which I can decide the SoftNAS is suitable AMI for my production use case. This is very high priority as I need to implement this for persistence storage for Kubernetes as EFS is not available in Mumbai region.”
“Need ability to use S3 as the backend storage instead of EBS/EFS as they are much too expensive for us.”

 

The above is a just sample of what we typically hear from customers, after they’ve evaluated or deployed EFS. Clearly EFS is a solid NFS-as-a-service that is meeting many customers’ cloud file storage needs. Some customers, however, need more than a multi-tenant, shared filesystem can possibly deliver.

What’s needed is a full-featured, enterprise-grade Cloud NAS that delivers:

  • a tunable level of dedicated, predictable performance
  • guaranteed cross-zone high-availability with an up-time SLA
  • storage efficiency features (e.g., compression, deduplication) that mitigate costs of cloud storage
  • support for EBS (Provisioned IOPS, SSD, magnetic) and highly-durable, low-cost S3 storage
  • a full-featured POSIX-compliant filesystem with full NFS that supports all the expected features at scale
  • CIFS with Active Directory integration and full ACL support for Windows workloads
  • Ability to scale storage into the hundreds of terabytes or petabytes, while maintaining performance consistency at a reasonable cost level that doesn’t break the bank or derail the project
  • Storage auto-tiering that maximizes performance while minimizing storage costs
  • Data checksumming and other data integrity features that verify retrieved data is accurate and correct
  • Instant storage snapshots and writable clones that do not involve making expensive, time-consuming copies of data for rapid recovery and previous versions
  • Integrated data migration tools that make lifting and shifting production workloads into the cloud faster and easier

How can SoftNAS address all these issues better than EFS?  Simple. That’s what it was designed to do from the beginning – provide cloud-native, enterprise-grade “cloud NAS” capabilities in a way that’s designed to squeeze the maximum performance from EC2, EBS and S3 storage. And cloud storage and data management is all we have done, every day, since 2013, so we are among the world’s top cloud storage experts.

Below we see SoftNAS Cloud running as a Linux virtual machine image on EC2. First, EBS and S3 cloud storage is assigned to the SoftNAS Cloud image that’s been launched from AWS Marketplace or the AWS Console. Next, that storage is aggregated into ZFS filesystems as “storage pools”. Then, these pools of storage can be thin-provisioned into “volumes” which are shared out as NFS, CIFS, AFP or iSCSI for use by applications and users.

SoftNAS leverages arrays of native EBS block devices and S3 buckets as underlying, scale-out cloud storage. Data is striped across arrays of EBS and S3 devices, thereby increasing the available IOPS (I/O per second).  To add more performance and storage capacity, just add more devices at any time.

SoftNAS Cloud runs on a dedicated instance within your AWS account, so everything is under your control – how many and what types of storage devices are attached, how much RAM is available for caching, how much direct-attached SSD to use (based on instance choice), along with how much CPU to allocate to compression, deduplication and performance. Incidentally, compression and deduplication can reduce your actual storage costs by up to 80%, depending upon the nature of your data (you don’t get any storage efficiency features with EFS).

And because ZFS is a copy-on-write filesystem and SoftNAS Cloud automatically creates storage snapshots for you based on policies, you always have previous versions of your data available at your fingertips, in case something ever happens. You can quickly go back and recover your data without rolling a backup-restore (you don’t get any storage snapshots or ability to recover with EFS).

ZFS provides complete POSIX-compliant semantics as the SoftNAS filesystem. CentOS Linux provides full NFS v4.1 and NFS v3 filesystem semantics, including native file_get_contents, is_dir functionality. And because SoftNAS is built upon Linux, you get native NFS support with no functional limitations.

SoftNAS Cloud supports Windows CIFS with SMB 3 protocol, with Active Directory integration for millions of AD objects. All of these details matter when you’re deploying applications that rely on proper locking, filesystem permissions and full NFS semantics, NTFS ACLs, etc.  You can drill deeper into SoftNAS Cloud Technology here.

SoftNAS delivers dedicated performance with two-levels of caching – RAM and direct-attached SSD for massive read-caching, which together provide both predictable performance that YOU control, as well as performance increases. And later if you need even more performance, you can simply upgrade your EC2 instances to add more IOPS and greater throughput with more network bandwidth.  SoftNAS keeps you in control, instead of turning control of your data over to the multi-tenant EFS filesystem and living with its various limitations.

What about cost savings through data efficiency features of SoftNAS Cloud?

SoftNAS provides 3 ways to reduce cloud storage costs:

  • Compression – compresses data and reduces required space (not available in EFS)
  • Deduplication – detects and eliminates duplicate data, saving more space (not in EFS)
  • Auto-tiering – policy-based block data tiering based upon actual data usage patterns (not in EFS or any other cloud storage product)

The drawing below shows our patent-pending SoftNAS SmartTiers™ and how it uses up to four levels of transparent, automatic storage tiering to save customers money and maximize cloud storage value.
