IT departments are increasingly moving to a cloud-like model for service delivery, as the end users and customers they serve expect seamless services that perform flawlessly, are always on, and that are available in minutes. To accomplish this, automation and orchestration are a must.
All-flash storage in general, and Pure Storage Flash Arrays specifically, provide an excellent foundation for high-performance cloud services. Only all-flash storage can deliver the near-instantaneous services that customers and business end users have come to expect. And only Pure Storage’s unique recipe for all-flash storage offers a powerful, highly available foundation for cloud environments that operates without disruption, ensuring reliable, consistent performance for services—even through upgrades, expansions and (however unlikely) failure scenarios.
So long RAID-5/6 vs. RAID-10 trade-offs. No more capacity and IOPS calculations. No more grouping disks, managing spares or day-long parity rebuilds. The Flash Array is automatically protected with dual-parity or better RAID-3D. Create volumes and go.
Where is the bottleneck? Host ports? Cache utilization? Director utilization? Back-end loops? Disk head contention? The Flash Array was designed to eliminate physical contention and associated tuning headaches—one large LUN performs identically to 1000 small LUNs.
tiering and caching.
Flash tier. Disk tier. Controller cache sizing. Data movement policies. Cache hit rates. Sizing calculations. Forget it all! Get the same great flash performance at low cost for all your data with the Flash Array.
host / array block alignment.
The database writes on 32K block boundaries, the VM is aligned to 8K page sizes, and the storage array likes 4K blocks…wait, does that work? Pure Storage’s 512- byte virtualization chunk size means none of that matters. Pick any host and application block size and get outstanding performance.
Sick of compensating for head contention via short-stroking your drives to less than 50% capacity? Sick of provisioning and powering 10s of GBs of extra DRAM to try to avoid waiting on mechanical storage? There has to be a better way. And there is.
It feels like virtualization in legacy arrays was just grafted-on: virtual pools, aggregates, hypers, metas, chunklets…enough already. Pure Storage provides one big pool, with all your storage. Create volumes and go.
