Wait or invest?

does it make sense for you to invest in an all-flash array today?

My washing machine is old but it still works – though I have to admit washing takes ages, requires a lot of water and electricity and I can’t select environmental friendly programs. That’s why I am thinking about buying a new one that will help me to save money and to keep up with technology. But the question is: should I buy now or wait until there will be the next wave of technical updates for washing machines? On the one hand, buying now will bring a washing revolution into my life; on the other hand, new technical updates mean better washing machines, most likely. But do I really need additional intelligence to simply wash my shirts and towels?

Similar questions arise when you are planning to upgrade your storage equipment for the data center. When is the right time to invest in new technology? Now or in a year’s time? Do I really need to wait for the latest technology when current offerings from various vendors can cater to all my requirements?

These days everybody in storage is talking about NVMe

This upcoming technology offers super fast performance and the chance to highly synchronize work streams. But do your applications really need it? Doesn’t flash storage already offer everything you need?

Not long ago, flash storage was something exotic and expensive and used only when high performance was an absolute must. Storage systems had been equipped with high capacity spinning disks and anyone who needed extra speed combined them with fast responding SAS SSDs.

It’s only two years ago since things changed. SSDs have become more reliable and all-flash arrays (AFA) have started to become mainstream in the data center as general purpose systems for any company size and usage area. They offer a lot of advantages compared to hard disk-based storage arrays, resulting in a far better TCO:

  • Less data stored: AFAs are fast enough for live data reduction; techniques include deduplication and compression. Ideally this technology can be switched on or off on a volume base to determine whether it should be capacity- or performance-optimized.
  • Automated control: AFAs can be run with less manual tuning and intervention, which means less need for expensive storage management skills on the routine operations side, potentially freeing up expertise to develop and support newer and more profitable services.
  • Less cooling, space and power: Flash offers far higher data density than disk. This means that using an AFA instead of a disk array often means solving the same problem with fewer drives, and significantly reduced costs for costly rack and floorspace. Less power and cooling means savings on the energy bills.

ETERNUS AF is a well-established all-flash array that offers all you need for the perfect new storage system in your data center. Besides, the general advantages of an AFA ETERNUS AF come with Automated Quality of Service for guaranteed SLAs and multiple possibilities to ensure continuous access to your business data (replication, snapshots or transparent failover via ETERNUS Storage Cluster). As a family of storage systems ETERNUS AF smoothly interacts with ETERNUS DX hybrid storage system, using the same management platform. Replication and failover can be performed seamlessly between ETERNUS AF and ETERNUS DX systems and the online migration feature allows transition from one system to another without downtime.

SPC benchmarks show that ETERNUS AF arrays are top performers. So, why wait for something in the future? Systems that offer an excellent price/performance ratio are already available today.

It’s time to go for an all-flash system now!
