  • Making a living taking surveys at home! I have been a stay at home mom for almost 5 years and I am so excited to be able to still stay home, take care of my children and make a living taking surveys on my own computer! It's so easy to get started and I plan to make enough money each week so that my husband can actuallly quit his second job!!! Thank you so much! ➤➤ http://t.cn/AieX2Loq

Five common customer use cases for Virtual SAN - VMworld US / 2015

  1. 1. STO4650-QT - Five Common Customer Use Cases for Virtual SAN Duncan Epping – Chief Technologist Lee Dilworth – Principal SE
  2. 2. Agenda • Introduction (Duncan) • Five Common Customer Use Cases for Virtual SAN 1. Production (Lee) 2. Management Cluster (Duncan) 3. ROBO Deployment (Lee) 4. DMZ / Isolation (Duncan) 5. Development Platform (Lee) • Q&A (if time permits) 2
  3. 3. We need to transform storage the way we transformed compute 3 Fast and Simple Provisioning Application-Centric Control Memory CPU Memory CPU Automated Self-Tuning
  4. 4. The hypervisor is best positioned 4(1) Gartner Market Trends: x86 Server Virtualization, Worldwide, 2013 Why the Hypervisor: • Over 70% of x86 server workloads are virtualized1 • It’s inherently app-aware • Sits directly in the I/O path • Has global view of underlying storage resources • It’s hardware agnostic vSphere
  5. 5. VMware Virtual SAN • Storage scale out architecture built into the hypervisor – 3 node minimum • Aggregates locally attached storage from each ESXi host in a cluster – Flash + Magnetic Disk or Flash + Flash • Dynamic capacity and performance scalability • Flash optimized storage solution • Fully integrated with vSphere and interoperable: • vMotion, DRS, HA, VDP, VR … • VM-centric data operations 5 vSphere + Virtual SAN … Magnetic Devices Flash Devices Magnetic Devices Flash Devices Magnetic Devices Flash Devices Virtual SAN Datastore
  6. 6. Two Ways to Implement VMware Hyper-Converged Infrastructure 6 • 50+ validated server configurations • Jointly recommended by VMware and Server OEM • Ready for Virtual SAN deployment • Build your own SDDC by adding VMware software components Virtual SAN Ready Node / BYO Certified Hardware Flexibility Ease of Use • Pre-integrated and pre-configured software with certified partner H/W • Software to simplify deployment, configuration and lifecycle management • vSphere, Virtual SAN and management software included EVO Family Integrated Systems
  7. 7. Yes… really simple! Virtual SAN is a cluster level feature similar to: – vSphere DRS – vSphere HA – Virtual SAN Deployed, configured and manage from vCenter through the vSphere Web Client – Radically simple • Configure VMkernel interface for Virtual SAN • Enable Virtual SAN by clicking Turn On 7
  8. 8. Use Case 1: Production 8
  9. 9. Production • VSAN isn’t just for VDI or Test/Dev • Most of our customers run Production and even Mission Critical workloads on VSAN – MS Exchange / SQL – Oracle – SAP – Billing Systems (6-7 million customers!) • Physical system runs for 22 hours • Virtual system on traditional storage 14 hours • Virtual system on VSAN 3 hours! • Growth pattern unknown? VSAN scales up and out! 9
  10. 10. Production – Typical Design • In production most used is a 2U server platform • 256 / 384GB and 2 x 10 core Intel (v3) CPU • Two disk groups is typical per server • Per disk group: – Disk controller SAS Expander – 400GB flash for read/write cache – 6 magnetic disks per disk group • Most customers use SAS • Note, more than 8 disks? SAS Expander! • Those who use NL-SAS buy more flash! • 2 x 10GbE 10
  11. 11. 11 Many customers run production workloads on Virtual SAN
  12. 12. Use Case 2: Management Cluster 12
  13. 13. Management Cluster • Typical 1U form factor, or 2U / 4 Node • Perfect fit for VSAN • “Externally” hosted Management Cluster – Not running on components you are managing • Typically small clusters of 3 or 4 hosts • Use of single CPU hosts not uncommon – Reduces cost 13
  14. 14. Management Cluster • Typically small clusters of 3 or 4 hosts – Take maintenance mode in to account! • Use of single CPU hosts not uncommon – Reduces cost (not just hardware, but also licenses!) • 64GB / 96GB memory • Single disk group – 200GB Flash – 5 x 1TB (NL-SAS) • 2 x 10GbE 14
  15. 15. But how do I run vCenter on VSAN before I have vCenter? • Bootstrapping method 1 – Local VMFS move to VSAN using Storage vMotion • Bootstrapping method 2 – Create VSAN using esxcli • Change the default VSAN policy to set “Force Provisioning” to 1 • Tag all the local devices accordingly (Is Local: true / Is SSD: true / false) • Create a new VSAN cluster using “esxcli vsan cluster new” • Add disks to the cluster using “esxcli vsan storage add” • Deploy vCenter to VSAN using the C# Client Read all about it on VirtuallyGhetto.com: http://bit.ly/1m3cO5o 15
  16. 16. Use Case 3: ROBO Deployments 16
  17. 17. ROBO Deployments • Virtual SAN very popular for ROBO • No need for dedicated storage appliance, leverage local disk slots – Lowers overall power and cooling requirements • Easy to manage, no special skills required • Can be managed centrally! – You are not stretching the cluster, just managing remotely • Virtual SAN can run “headless”, network down to main site does not impact workload! 17
  18. 18. ROBO Deployments • Typically small clusters of 3 hosts • Use of single CPU hosts not uncommon – Reduces cost • 64GB / 96GB • Single disk group – 200GB Flash – 3-5 x 1TB (NL-SAS) • 4 x 1GbE – Create multiple VMkernel interfaces for VSAN or.. – Use IP-Hash (requires specific switch configuration!) 18
  19. 19. Use Case 4: DMZ / Isolation 19
  20. 20. DMZ / Isolation • Customers today typically run fully isolated except shared storage • Buying a separate array for just DMZ is too expensive • Smaller arrays do simply often not offer same performance or features • Very common use case for VSAN, as it will offer full isolation! • Examples: Mini data center on Trains, Oil Platforms, Boats… 20
  21. 21. DMZ / Isolation • 1U or 2U/4 Node systems • Configuration greatly varies depending on VM requirements • Interesting configuration I’ve seen: – All-flash VSAN • Lower power consumption • Minimize moving parts • And a great performance… • Dell FX2 System with FC430 Compute and FD332 Storage Blades – Networking, 10GbE switch, in the box! 21
  22. 22. Use Case 5: Development Platform 22
  23. 23. Development Platform • Programmatically accessed • Differentiate through policies instead of tiers • Fast provisioning, agile, and no impact on production • Running next to the traditional infrastructure • Extend existing platform to meet “different” needs • Front-end VSAN/vSphere with VIO, vCloud Director, vRealize Automation 23
