McKesson Horizon Clinicals Deployment History
1990’s – 2000’s - Big Iron - Big Unix - Big Sans AIX 4–6 HP 10-11 EMC Symmetrix/Clariion IBM Shark Network Appliance Whatever the customer/sales team defined
The Linux Revolution
Separate applications onto individual nodes
Red Hat on Dell, HP & IBM x86-64 racked servers
Oracle RAC for database applications
Still on large SAN technology
Lower TCO
First deployed Fall 2005
A Need to Evolve Cross-platform development Multiple physical architectures Multiple O/S Different:
hostnames network architectures SANs setups
SaaS – hosting for clients
Three Fold Change Hardware Change – Common: Server Storage Network Software – Standardize Operating System Applications Database – (RAC / non-RAC) Administration infrastructure
What is a systems appliance? Overview
A systems appliance is collection of servers, software, storage, and networking, in a managed enclosure.
This includes application, web, provisioning, distribution, directory, and database servers, and the associated technologies.
Simplifies deployment, management, upgrading, and scaling of our products.
Reduced time, from order to delivery, for the customer.
Compact and power efficient package.
Better management of security and networking.
Appliance Views
Systems Appliance Technology HP C-class blade enclosures
C3000 enclosure − Redundant backplane − Redundant power and cooling − Redundant high speed networking − Virtualized servers
64 processor cores
512GB RAM
3.4TB shared storage in RAID 5
LTO-3 tape backup
C7000 enclosure − Same as C3000 with:
128 processor cores
1.024TB RAM
Both enclosures are expandable up to 10 units
Systems Appliance Technology BL460c server blade
Dual processor, quad core Intel X5400 series
64GB fully buffered RAM
Up to 6 - 1 Gigabit NIC’s
MSA2012i SAN
3.4TB in RAID5 accessible by all blades
iSCSI SAN with clone and snap capabilities
StorageWorks 1/8 Tape Library
LTO-4 Ultrium tape drive
6.4TB native and 12.8TB compressed Backups
Configuration example C3000 enclosure with full compliment of blades
Configuration examples C7000 enclosure with full compliment of blades
Configuration options Using blade technology and virtualization, a multitude of configurations are possible.
The basis for the system is the VM hypervisor, allowing complete virtualization of the appliance.
Blades boot a hypervisor loaded onto internal USB keys, eliminating hard drives.
Server images will be stored on, and accessed from, the MSA SAN.
Database files will reside on the MSA under ASM.
All content is loaded into and backed up from a single location.
Configuration Options
The Horizon Clinical Infrastructure: application servers, webapps, forms and databases are all virtualized.
Staging will be done directly onto the MSA with complete pre-configured architectures.
Resources will be automatically deployed as needed to accommodate load.
The system can be grown by adding more blades and enclosures.
Multiple enclosures can be joined by a high speed interconnect.
All systems have remote management and configuration capabilities.
Components of an Appliance
Microsoft Active Directory Cluster Oracle RAC Database on Oracle Enterprise Linux Oracle Enterprise Linux for McKesson Apps/Webservers Citrix NetScaler HA pair VM software (Oracle, Citrix, VMware, etc) Citrix Provisioning Server
Speed Higher speeds than a racked system of servers
C3000 and C7000 enclosures use a dual 5TB backplane for interconnectivity.
Multiple appliances can be connected to act as a single unit.
Networking in the enclosures is also handled with high speed network modules or switches.
HP blade servers get the newest technology first.
Imaging Common storage based images Only the virtualization hypervisor layer resides on the blades. Server images reside on the shared MSA storage.
Database files reside on the MSA via ASM
Image files contain the entire software configuration.
The files are portable, and are simply imported onto the storage.
Imaging will result in a single OS and application file that can be upgraded and tested in a manner that is transparent to the customer.
The entire appliance can be configured in-house, and shipped as a package.
Maintenance Centralized management of appliances
All blades and enclosures can be managed from a single console.
All management can be done remotely.
All virtual images can be managed from a single console.
Upgrades can be brought online in parallel to live data, then switched over.
Up to 100 enclosures and 1,600 blades can be managed as a single entity.
Virtual servers can be migrated live, both manually and automatically, in the event of failures in the hardware.
Energy Usage
C3000 Cabinet with full compliment of blades (8) and 14 VMs: 1725 watts
MSA (Modular Storage Array) – 700 watts (2 power supplies running at ½ power each)
Dell 2950 : 350 watts * 14 = 4900 watts
SAN power requirements vary on model
Discounting storage, the appliance is at least 3x more efficient
Security and load balancing Hardware based security and load balancing
Because the appliance is a self contained computing and networking system, we can implement load balancing and security in a simple and effective manner.
Citrix NetScaler pairs are used as a firewall and load balancing switch for our applications.
The advantages of this approach: Restricting server access from the network Controlling user access Application load balancing Accelerating ICA connections from the internal Citrix farm Load balancing will not require switch hops for packets
Disaster Recovery Solid DR capabilities
Because the appliances are identical in components, we are only concerned about the storage.
Tools such as SAN based cloning, will replicate the entire environment live from one site to another.
An LTO-4 Ultrium tape library will be provisioned with each appliance for backup and recovery.
If an appliance fails due to a natural event, simply provision a new appliance and join it to the farm, and the live data will be restored to the new appliance.
Oracle Standby database can be used across campus or across the country.
Development Advantages Advantages with the appliance approach
A single platform significantly reduces our development costs
Better pricing when buying large numbers of a single platform
Significantly reduces maintenance costs associated with supporting multiple platforms and operating systems
Data center is not required, a room with adequate ventilation flow that can be kept below 75F with two 30a/240v circuits will work
Reduced Customer Cost - TCO The customer will realize significant savings
An appliances will consume less power than an equivalent server setup.
The SAN is integrated into an appliance, this can save a customer hundreds of thousands of dollars in additional hardware, complexity, and 3rd party maintenance costs.
Administration of an appliance will be much simpler than a similar configuration of racked servers.
There are significantly lower services costs associated with imaging technology.
There are much lower support costs with the standardization of images and hardware.
Database Options Non-RAC–Single full blade (2 quad-core processors) up to 64G RAM RAC – Provision full blade as VM with up to 64G RAM Interconnect via cluster virtual network on private subnet If blade fails, the VM image can be brought up on another blade Expansion: Add a new node, provision and use RAC to add a new node to the cluster.
Why RAC? Failover capability Load balancing Rolling upgrades of database and/or application Additional capacity is simple to add With multiple cabinets, stretch clusters are possible with mirrored ASM diskgroups
