Being close to our customers and focusing on solving their strategic IT
challenges has been a key tenet for Pure Storage since day one.   

When we talk to front-line IT staff and business leaders, they’ve been
consistent with their commentary: 

 * “How can you help us meet our data and application growth?”  
 * “How can we end the painful data migration and related storage upgrade
   cycle?” 
 * “What we need is more IT agility, allowing us to respond faster and focus
   resources on higher-value strategic IT initiatives”

Legacy Storage Upgrade Cycle




LEGACY STORAGE IS THE OPPOSITE OF IT AGILITY

Anyone who has deployed legacy storage knows the pain of this cycle well—it’s
complex, wasteful, and time-consuming. Complete overhauls of the storage
infrastructure—the dreaded “forklift upgrade”—are required every few years to
meet the growth of data and applications. This is due to the limited, rigid
architecture legacy storage uses, which was never designed for
upgradability—especially between storage generations. With traditional storage
architectures, this painful cycle will repeat itself again and again. 

It’s the antithesis of the IT agility that organizations are actually looking
for.


GUARANTEED TO ELIMINATE DATA MIGRATIONS, FOREVER

With our recent No Data Migration Guarantee/SLA announcement, customers can say
goodbye to disruptive data migrations with 100% non-disruptive upgrades that
keep data in place and with zero impact to critical workloads. Once a customer
is on the unique Pure Storage® Evergreen® architecture—the foundation of our
FlashArray™ and FlashBlade® future-ready storage solutions—we guarantee an end
to all data migrations. Customers can take advantage of this new No Data
Migration Guarantee/SLA announcement on all three of our subscription
offerings—Evergreen//One™, Evergreen//Flex™, and Evergreen//Forever™.


EVERGREEN ARCHITECTURE: NON-DISRUPTIVE TO THE CORE

At the foundation of this new SLA offering is Pure Storage Evergreen
architecture. We designed future-ready storage solutions to solve the challenges
customers face during the traditional storage life cycle, breaking it once and
for all. 

Pure Storage does this with a modular, software-driven, stateless architecture
that was built—from the very start—to be upgraded non-disruptively. It’s
engineered to never be taken offline when expanding capacity or upgrading
software or hardware. With this approach, our future-ready storage solutions can
seamlessly meet your business and IT requirements over time, no matter how fast
your data needs may change. 

This Evergreen architecture is common across our entire product line, including
every Pure Storage FlashArray model (FlashArray//X™, FlashArray//C™, and
FlashArray//XL™) and FlashBlade//S™.

These upgrade capabilities include:

 * Upgradeable controllers, blades, and even chassis that deliver the
   performance needed to meet modern workloads and applications, with zero
   impact to operations. 
 * Cross-generational flash compatibility, where different flash geometries and
   generations can be mixed within an array, and newer controllers work
   seamlessly with existing flash modules. (Competitors take note: If flash
   storage needs to be replaced when upgrading controllers, how is that
   different from a forklift upgrade?)
 * The ability to utilize new software functionality and features with
   previously deployed storage, without the need to upgrade hardware.


NON-DISRUPTIVE UPGRADES ARE NOT A NEW PHENOMENON FOR PURE STORAGE

This approach has been customer-proven across nine hardware generations, for
well over 10 years, and well over 10,000 controller upgrades. For over a decade,
Pure Storage customers have successfully embraced our Evergreen architecture,
enabling them to keep their storage modern and performing without rebuys or
disruption. In fact, over 97% of all Pure Storage arrays ever sold are still in
service today because it’s so simple to keep them forever modern and performing
like new arrays.

We innovate and invest in R&D at levels two to three times that of legacy
storage vendors. A lot of that innovation has been focused on making storage not
only simpler for our customers to use but also far denser, the most energy
efficient, and always upgradable without disruption. That means our storage is
also much less expensive to own and run (and keep modern) than either all-flash
or hard-disk legacy storage. 

And this focus is especially true for storage upgrades. We continue to do the
hard work—engineering, development, and testing—to ensure that all our upgrades
are truly 100% non-disruptive. 

You can even say it’s in our DNA.


CUSTOMER STORY: MULTI-GENERATIONAL STORAGE UPGRADE FOR CRITICAL PATIENT CARE
DATA

For a major U.S. healthcare organization, we recently non-disruptively upgraded
from their existing Pure Storage FlashArray//X storage array to the new
FlashArray//XL and are planning to do the same for their production arrays
supporting their Epic electronic medical records (EMR) infrastructure. We moved
the organization from one entirely different storage generation (and chassis) to
another, without planned downtime, without impact to workloads and application
availability, and without migrating their data. 

This is the most comprehensive multi-generational upgrade we’ve ever done,
changing everything out with zero disruption. 

As impressive as it might be to achieve this milestone once, this is the third
cross-generational, new-chassis upgrade out of the nine FlashArray hardware
generations we’ve delivered to our customers over the last 10+ years. While Pure
Storage customers have rightly come to expect this kind of upgrade from us, it’s
unique in the storage industry. Major generational FlashArray upgrades have
included:

 * In 2013, upgrading from our original FlashArray FA300 to the FA400, including
   swapping the controller chassis.
 * In 2015, moving from the FA400 to the NVMe-ready FlashArray//M, which once
   again changed the controller chassis (which was pre-plumbed to work with
   NVMe).
 * In 2018, upgrading from FlashArray//M to the all-NVMe FlashArray//X, which
   was achieved by just swapping the controllers (since we’d already delivered
   the NVMe chassis with the //M generation).

This is IT agility delivered by Pure Storage.
