AGENDA

Introduction – Elastic Cloud Tools & Utilities Hardware elasticity OS elasticity Network elasticity Storage elasticity

Introduction – Elastic Cloud

Amazon elasticity – Ability to pay per quantum of time.

So where is the elasticity ?

Introduction – Elastic Cloud

Cloud elasticity – Do IT online !!! Ability to change resources of a VM – online. Ability to utilize and share the hardware better – online. Ability to change hardware to your specific needs – online. Ability to utilize the OS better for its’ specific needs – online. Ability to utilize the Network and storage better – online.

Tools & UtilitiesEnterprise Manager SUITE Oracle Cloud control –

Mainly manages application tierOracle DB, Weblogic, SOA, Glassfish, etc...

Oracle OPS Center – Manages Hardware, OS, Hypervisors, VM’s, Storage, Network Fabrics, etc…

Oracle VM Manager – Manages OVM X86 & SPARC

Tools & Utilities Oracle VM for SPARC

A set of packages (in Solaris 10/11)that offers HW virtualization in T-series servers.

Oracle VM for x86A Xen based hypervisor that operatesas a Hypervisor for X86 platforms.

Both offers: CLI or GUI management via OPS Center – or – VM Manager

Hardware Elasticity

Imagine your hardware can transform itself from

1 core = 8 vcpu (max-throughput) to 1 core = 1 vcpu (max-ipc)

This can be done via Oracle VM for SPARC Control domaine.g.: ldm set-core threading=max-ipc | max-throughput ldom

* This feature is deprecated but was brought to emphasize the elasticity of SPARC platform.

Hardware Elasticity

Ldom elasticity policyldm add-policy [enable=yes|no] [priority=value] [attack=value] [decay=value] [elastic-margin=value] [sample-rate=value] [tod-begin=hh:mm[:ss]] [tod-end=hh:mm[:ss]] [util-lower=percent] [util-upper=percent] [vcpu-min=value] [vcpu-max=value] name=policy-name ldom...

Oracle VM for SPARC supports mixed Solaris versions Support for running Solaris 10 and Solaris 11 VMs.

OS Elasticity Critical thread – ability to bring CPU bound process more

hardware space. (by setting the priority of this process to 60 using FX priority or RT scheduling classes).

Datalink Multipathing Aggregations – Overcomes the single switch boundary.

Multipathing – IO Multipathing supports mixed paths (e.g.: iscsi, fcoe and fc together.)

FC – FC lun changes are reflected immediately. Fast reboot mechanism – by using: reboot –s OS Snapshots – Snapshot a root file-system within the OS

using: beadm

OS Elasticity – cont.

Patching & Upgrading – patching and upgrading using live-upgrade can be rolled back.

Ability to run zones – a lightweight virtualized VM with a lower footprint.

Ability to run branded zones – Solaris 10 zones.

Storage Elasticity

ZFS – Ability to add devices, ability to split pool, ability to grow luns of a pool on the fly – online.

Multipathing – IO Multipathing supports mixed paths (e.g.: iSCSI, FCoE and FC together.)

NPIV – N_Port ID Virtualization is a Fiber Channel facility allowing multiple N_Port IDs to share a single physical N_Port. This allows multiple Fiber Channel initiators to occupy a single physical port, easing hardware requirements in Storage Area Network design, especially where virtual SANs are called for.

COMSTAR - ability to create luns and expose them using FC/FCoE/iSCSI etc…

Network Elasticity

Datalink Multipathing Aggregations – overcome the single switch boundary. Ability to add or remove devices – online.

SR-IOV – Single root IO virtualization now supports NIC that can expose itself as several virtual devices. Each virtual device is a physical entity in the card. Packet manipulation is done by the hardware.

Network virtualization – ability to create switches and vnics and to attach it to zones.
