The document outlines five common customer use cases for VMware's Virtual SAN, highlighting its applications in production, management clusters, ROBO deployments, DMZ/isolation, and development platforms. It emphasizes the benefits of Virtual SAN, such as scalability, ease of deployment, and integration with vSphere, and provides details on typical configurations for each use case. The document also discusses the importance of transforming storage in line with compute advancements and presents various implementation approaches for hyper-converged infrastructure.
Five common customer use cases for Virtual SAN - VMworld US / 2015
- 1. STO4650-QT - Five Common Customer Use Cases for Virtual SAN Duncan Epping – Chief Technologist Lee Dilworth – Principal SE
- 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. 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. 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. 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. 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. 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. Use Case 1: Production 8
- 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. 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 Many customers run production workloads on Virtual SAN
- 12. Use Case 2: Management Cluster 12
- 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. 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. 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. Use Case 3: ROBO Deployments 16
- 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. 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. Use Case 4: DMZ / Isolation 19
- 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. 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. Use Case 5: Development Platform 22
- 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
