Environmental Data Disaster – We have a data problem not a storage problem. •

Environmental Data Disaster – We have a data problem not a storage problem. • Many believe that data is the new oil, which drives our economy. • If so, we have not realized that we have a waste management problem. • Your data can turn into a toxic asset, which will cost time and money to manage. • We cannot keep on buying more storage we need to manage the data better. Manage Data which will manage Storage Before It Gets Out of Control 9 © 2017 Gartner, Inc. and/or its affiliates. All rights reserved.

Flash Everywhere, Solid State Memory Crossover § Consumer devices use more flash than data

Flash Everywhere, Solid State Memory Crossover § Consumer devices use more flash than data centers: – Causing price increases, demand increases § Data centers will use "laptop flash": – "Consumer grade" will decrease flash array price § New solid state memory will increase performance: – Will be used for caching, IMC and many other applications — ZNAND 10 © 2017 Gartner, Inc. and/or its affiliates.

Effective Capacity Improves Storage Efficiency § Traditional Usable: § Effective Capacity: – Raw — RAID/Spare overhead – Usable plus data reduction – Sell a 100 TB array – Data reduction – Usable is about 90 TB-95 TB § Compression § Deduplication – Flash arrays cost between three to five times more than hybrid array on raw capacity – If customer can obtain 3: 1 data reduction (or higher) then the flash array is same price as a hybrid array 12 © 2017 Gartner, Inc. and/or its affiliates.

NVMe Replaces SCSI, Not SANs or NFS NVMe is a replacement for SCSI §

NVMe Replaces SCSI, Not SANs or NFS NVMe is a replacement for SCSI § Flash is memory: Outside of the array server NVMeo. F requires Fibre Channel or Ethernet to be useful in a network. – SCSI was serial access for mechanical serial hard-disk drive (HDD) storage. – NVMe allows storage to be accessed like memory: § More simultaneous accesses: – Allows larger queues (more users). – Allows more tasks (more multi-threading). – NVMe when networked will be called NVMeo. F in a Ethernet or Fibre Channel SAN. 16 © 2017 Gartner, Inc. and/or its affiliates. All rights reserved. The main change is that storage is accessed as memory. But you need a SAN to connect it all!

Storage Changes Shape (but Probably Still a Box!) § There is no need to have 2. 5 or 3. 5 inch disk drives. § This will allow storage arrays, servers, integrated systems and Io.
