“While we initially chose VMware virtual

infrastructure to address development hardware problems by reducing hardware costs and decreasing server

deployment time, we soon discovered additional benefits to adopting the technology, including

server portability, protection, and

availability.”-- Keith Leahy,

VI3 Customer Storage Trends


Current (as of 10/07) Future (end of ’08)

Q: What proportions of your current VMs running on ESX Server are on the following types of storage? (N=7320)

Trend is to move from DAS (or internal disk) to shared storage within the year.

Shared Storage Dominates


Q: For the majority of your current and planned VMs stored on iSCSI arrays, where is the iSCSI initiator placed? (N=7320)

In-guest vs. Hypervisor level

If at hypervisor level, then s/w or h/w?

Software iSCSI Preferred


...in a filesystem (VMFS, NFS)

...on raw devices (RDMs, iSCSI in-guest)

Where do customers store their VM’s?

Only use filesystem

Are customers 100% filesystem, 100% raw device, or some mix?

Only use raw device

Mix of both

VDI Challenges


The VDI market



VDI


Reduce the required storage… while maximizing performanceEnable the provisioning of large numbers of virtual machines in real timeEnable laptops to run disconnected, and resync upon reconnecting

Storage and VDI


Separate the user data from the OS & app imageThen, leverage lightweight clones to handle the OS & app disk.

Dramatically reduce the amount of storage consumed

Storage for VI Business Continuity


Write replication adapters for Site Recovery managerDirectional: enable VCB to leverage array-based snapshotsDirectional: storage services on a per-VM basis

Implement array-based mirroring with both arrays allowing writes (i.e. fully active-active)…. for both LAN/MAN and WAN.

Key VI Initiatives


VMware SMB Market Survey, June, 2007 n = 501Q. The following is a list of potential problems that your company could have with its computing environment. Please rate how serious of a problem each one is for your company. (On a 1-8 scale, 8=extremely serious problem).

Q. Please indicate the relative amount of investment your company is likely to put into addressing these issues in the next 12 months. (On a 1-8 scale, 8=very high investment in addressing this).

Top spending areas are DR, backup, security and availability
