14 slides from Qnap Systems's technical presentation, Feb 3, 2016
Slide 1: Qtier™ Technology
Qtier™ Technology Constant optimization of data across storage tiers. Jérôme Jaussaud, Senior Product Manager
Slide 2: Agenda
Agenda • What is Qtier™ - Auto-tiering • Demo environment • How easy is to create a storage pool with auto- tiering • Quick VDI test environment • Quick VDI test results : how many desktops with Qtier ? • Some recommendations
Slide 3: Today, without Qtier™
Today, without Qtier™ SATA SSD SSD SATA SSD SATA Full of SATA/NL-SAS Full of SSD Both SATA and SSD disk • Very Fast !! • Very Fast • High Capacity • Large Capacity • …but very • …but not very fast Expensive • …but it need to • And not that big separate manually capacity data between both • Not conve
Slide 4: Qtier™: multi-tier storage
Qtier™ : multi-tier storage • Qtier™, is a multi-tier storage management system. • Maintain most active data to the high- performance drives • 3 Levels of tiered storage – Tier 1 : SSD (SAS/SATA) – Tier 2 : SAS hard drives – Tier 3 : SATA or NL-SAS drives • Lighten the burden on administrators Examp
Slide 5: Qtier™: multi-tier storage
Qtier™ : multi-tier storage • Based on access frequency • Background & online data movement • Scheduled data movement • Adjustable optimization options • Choose which tier to use first • Supports 2 Tiers or 3 Tiers* * Only SAS models support 3 tiers
Slide 6: How easy to create an auto-tiered storage pool!
How easy to create an auto-tiered storage pool! – TVS-EC1580MU-SAS-RP with Qtier™ enabled • 6x SAS-SSD : SEAGATE 1200.2 SSD 200GB (SAS) - RAID5 • 9x SATA drives : SEAGATE NAS-HDD 2TB (SATA) - RAID6 Total capacity : 14 TB – Client server is a server with Windows 2012 R2, only 8 GB RAM to avoid memory
Slide 7: How easy to create an auto-tiered storage pool!
How easy to create an auto-tiered storage pool! • On the TS-EC1580MU-SAS-RP: – Create the Qtier storage pool – Create an iSCSI LUN • On the Windows server: – Connect the server to the iSCSI Target / LUN – Format the LUN – Start the IOmeter test
Slide 8: How easy to create an auto-tiered storage pool!
How easy to create an auto-tiered storage pool! • TS-EC1580MU-SAS-RP – 6x Seagate SAS-SSD – 9x Seagate SATA NAS HDD • 4K , 100% random read IO • ~130,000 IOPS with average latency lower than 0.5ms!
Slide 9: Quick VDI test results: How many desktop with Qtier?
Quick VDI test results: How many desktop with Qtier? –Test Software : Login VSI to create real workloads using real user behaviors and applications. –Virtualization Environment : • Cluster of 6 servers with a total of 750 GB RAM and 20 Cores • VMware ESXi 6.0 + Horizon View with 200 VMs running Wind
Slide 10: Login VSI using QNAP NAS with Qtier
Login VSI using QNAP NAS with Qtier After auto-tiering, this VDI test environment can run smoothly up to 195 desktops, with 8 SAS-SSD. 195 VMs
Slide 11: Login VSI using QNAP NAS with Qtier
Login VSI using QNAP NAS with Qtier From vSphere Client, we can see that we need more servers to test more VMs. The VMware cluster used for the test reached its maximum capacity.
Slide 12: Qtier or SSD read/write cache?
Qtier or SSD read/write cache? It’s a case by case, depending on the applications workloads... However, as general answer: • SSD read/write cache for small configurations. • 4~6 SDD read/write cache makes a huge difference. • SSD cache requires more memory than Qtier. • Qtier for large needs in SSD.
