VMware Server Virtualization

Large VM estates suffer from “memory Ballooning”

Memory Ballooning is when ESX server RAM is full and the ESX hosts “swap out “ to a spinning disk LUN

>5ms latency from disks for swap outs impact VMs dramatically – especially in a large estate

VMs wait for responses, IO can pause and IO can timeout causing VM Hangs or even Crashes

Impact to production apps or hosts systems if Managed

Fabric

• A small amount of Flash presented as block

LUN to ESX clusters

• Shared access to memory array by clusters to “swap out “ to

• <0.5ms avoids VM hangs and crashes

• Memory array LUNs can also be used for VMs and there apps – Tier 0


Virtual Desktop - VDi

• Images require many IOPs – 20 -70 depending on Image OS and user profile

• 1000+ images creates huge IOP requirement for storage

• 1000s of IOPs requires large Bandwidth

• Gold images and Linked Clones reduces storage capacity requirement

• Storage utilization is poor

• Large cap-ex, complex to setup and manage

• Large op-ex costs – power, heat and space

• Violin Flash Array provides 100,000s of IOPS

• 4GB/s bandwidth per array

• Sustained Read AND Write IOPS

• Eliminate boot storms and log off storms

• Enable virus scanning and security

• Enable thin or thick apps

• Persistent or non-persistent

• Simple to use – lower capex and opex


Infrastructure Consolidation – Requirement

Typical Project:

- 20TB total usable capacity (single or consolidated

apps/databases)

- Combined requirements = sustained 500,000 I/O per

second 4KB transfers this is 2GB /sec (500,000 * 4KB)

- Mixed Database workload (R:W 2:1 ratio)

- 100% growth over three years

Classical HDD-approach:

15k rpm SAS Disk 200 IOPS

1’500 Harddisks

Need to buy: 450TB (assuming 300GB disks)

Violin Approach:

2 x 6232 Memory Array

Need to buy: 64TB


Infrastructure Consolidation - Server Compression

Challenges:

- Multiple SQL hosts/DRAM for performance

- SQL Licencing costs

- Cache contention in SAN Arrays

- Complex Storage Management

Fabric

Violin Flash Memory Benefits:

- Significant reduction in server footprint

- Reduced power costs

- Reduced SQL/VMware licencing costs

- Latency in microseconds rather than milliseconds

- Eliminate Cache contention issues

- Existing disk arrays redeployed for Tier 3 / Archive

- Longer term only Flash and SATA disk

- Dramatically simplified data management

General Recommendations:

─ Typical Applications:

MS-SQL, SharePoint, Exchange, Hyper-V

─ Simply map LUNs via FC to Application Servers

─ Best practices for FLASH – high IOPS/low latency:
