3. Generations of the EVA family
Managing HP Enterprise Virtual Array
Solution Overview
Historical progression of the EVA family, from oldest to newest:
First generation (Gen 1) (not covered in this course)
EVA3000/5000 series
HSV1x0 model controllers
Second generation (Gen 2)
EVA4000/6000/8000 series
EVA4100/6100/8100 series
HSV2x0 model controllers
Third generation (Gen 3)
EVA4400
HSV300 (and HSV300-S) model controllers
Fourth generation (Gen 4)
EVA6400/8400
HSV400 and HSV450 model controllers
Instructor notes
For the most part, EVA generations are based on controller generation, from HSV1x0 to HSV4x0.
The customers may have all four generations of storage systems to be able to look at. Ask what models they themselves have installed or are being installed at their sites.
The EVA 3000/5000 series is no longer actively sold, however, ongoing support is provided for these arrays at customer sites. Point out that these arrays will not be covered in detail in this course, as the course will focus on current arrays (second through fourth generations).
Customers may hear or see abbreviations for each generation:
GL (EVA 3000/5000)
XL (EVA 4000/6000/8000 and 4100/6100/8100)
LE (EVA4400)
DEXL (EVA 6400/8400)
EVA8400 (dual rack)

5. Managing HP Enterprise Virtual Array
Product features (2 of 2)
Managing HP Enterprise Virtual Array
Solution Overview
Scalability
Up to 16 arrays per fabric
Up to 2,048 LUNs per array
Up to 256 hosts per array
Presentable (virtualized) capacity (based on current drive capacity)
56TB (EVA4000/4100)
112TB (EVA6000/6100)
240TB (EVA8000/8100)
96TB (EVA4400)
216TB (EVA6400)
324TB (EVA8400)
Instructor notes
Values are given in decimal, not binary. Therefore, 300TB decimal, as used for marketing, really translates to 273TB binary.
This is the limit of storage presentable as LUNs, not necessarily the physical capacity of all drives.
There is messaging in the Command View EVA GUI that tells the user when the virtual capacity has been exceeded.

6. Managing HP Enterprise Virtual Array
Key EVA values
Managing HP Enterprise Virtual Array
Solution Overview
Higher utilization of purchased capacity
No pre-configured RAID sets
All spindles active when in a disk group
Several replication choices
Business Copy EVA for local replication
Continuous Access EVA for remote EVA replication
Automatic, self-tuning performance
Greatly reduced planned and unplanned application downtime
Simplified management
HP Remote Support services (phone home)
Instructor notes
Higher utilization of purchased capacity refers to comparison to traditional RAID configurations. There are no preconfigured RAID sets. VRAID and sparing span all disks within the disk group, so there are no idle “spare” drives found within the configuration.
Remote support tools include Web-Based Enterprise Services (WEBES)/System Event Analyzer (SEA), Remote Support Pack (RSP), and Insight Remote Support (Insight RS). As a no-charge option, HP will install remote service tools for any EVA under warranty or service support. These tools enable self-monitoring and diagnosis. The EVA transmits status information to an HP service center for proactive problem resolution. This requires HP Hardware Support assistance. Customers should contact local support for details.

8. Virtualization technology
Managing HP Enterprise Virtual Array
Solution Overview
Abstraction of physical storage
Storage pools (disk groups) created from physical blocks of storage
Virtual disks (vdisks) created from the storage pool
Physical devices and capacity distribution transparent to servers and applications
Server
Virtual disk
Physical LUNs
Storage arrays
Storage virtualization
(physical to virtual block-level mapping)
Instructor notes
There is block-level I/O mapping that allows mapping of physical LUNs to virtual disks. The HSV controller assigns the logical blocks of a virtual disk to specific physical disk blocks through a dynamic map managed by the controller. This is similar to page tables in a virtual memory operating system, with minimal overhead in the I/O path.
Emphasize that the EVA implements virtualization at the storage system level. Other products use virtualization at different levels, for example:
HP Secure Path/MPIO use virtualization at the HBA.
HP Logical Volume Manager (HP-UX, Linux) offers OS-based virtualization.
Veritas Volume Manager offers UNIX host-based virtualization.
HP OpenView Storage Volume Growth (Windows) uses virtualization at the host level.

9. Functional layout of the EVA solution
Managing HP Enterprise Virtual Array
Solution Overview
Functional layout of the EVA solution
Administrator uses Command View EVA GUI (through web browser) to configure the storage required by hosts
Management is done “in-band” over the storage fabric
Command View EVA allows
Windows server-based management (SBM) or VMware Guest OS (CV 9.2)
EVA4400 array-based management (ABM) on the Management Module
Creation and presentation of virtual disks
The host sees the virtual disk as a physical drive
XCS
Instructor notes
Command View EVA, as of version 3.3, was installable on the OpenView Storage Management Appliance (SMA) as well as a fabric-attached Windows Server (with specific requirements). The non-SMA version of Command View uses the term Storage Management Station (SMS) as the name for the system that replaces the SMA. The SMA is no longer a requirement for the EVA solution and is considered at end of life. The current release of Command View EVA is 9.3 and is supported on the SMS for server-based management (SBM) as well as the Management Module of the EVA4400 for array-based management (ABM).
Business Copy EVA (as of version 2.3) as well as Continuous Access EVA (as of version 1.1b or 2.0) also run on the Windows Server platform.

10. Physical layout of the EVA solution (EVA8000 or EVA8100 shown)
Managing HP Enterprise Virtual Array
Solution Overview
Fabric Ports/Fibre Ports/Host Ports (Front End)
Ports connect array to fabric and support direct connect host connectivity.
High-end models have 4 fabric ports per controller
Low/mid-models have 2 fabric ports per controller
Mirror ports
Used for mirroring of writes from one controller to another.
Two ports per controller for some models. EVA 4400 does not have mirror ports.
Data Ports/Device Ports/Device Pairs/Loop Ports/Loop Pairs (Back End)
Arbitrated loop
Dual loop connections
Ports used to physically connect drive shelves to the controllers
Loop Switches may not be present on all models
Instructor notes
Emphasize that this is for first- or second-generation EVAs.
Direct connect is supported on Windows, Linux, and HP-UX.
Physically, the storage system consists of a pair of controllers and their array of physical disk drives. The physical disk drives plug into disk drive enclosures.
The controller pair is cabled to the disk drive enclosures. A backplane in the disk drive enclosure distributes commands and data to the disk drives.
The controller pair connects to up to four Fibre Channel fabrics, to which the hosts also connect.
The Command View EVA software allows configuration and control of the storage system. It may reside on the Storage Management Appliance (SMA), a separate management server, or on the Management Module of the EVA4400. The software enables creation of virtual disks and presents them to a host, which sees the virtual disks as physical drives.
The controller pair connects to the physical disk array through Fibre Channel arbitrated loops or switched loops. The EVA5000 and EVA 8000/8100 connections use four Fibre Channel loop switches, the EVA 6000/6100 uses two Fibre Channel loop switches, and the EVA3000 and EVA 4000/4100 do not use loop switches.
For the EVA5000 and EVA 8000/8100, two separate loop pairs are used: loop pair 1 and loop pair 2. Each loop pair consists of two loops, each of which run independently and can take over for the other loop in case of failure. The EVA3000, EVA 4000/4100 and EVA 6000/6100 use a single loop pair.

Controller 1 NL NL

EVA N
Fabric F F
Instructor notes
The mpx100 serves as the data transport between iSCSI hosts and the EVA storage system. The mpx100 connects to iSCSI hosts through IP connections. With an iSCSI direct connect solution, the mpx100 connects directly to the host ports on the EVA controllers.
For this to work, the host port on the controllers that connect to the mpx100 must be configured for direct connect. This results in Fibre Channel arbitrated loop (FC-AL) protocol rather than point-to-point protocol.
The second host port on the controller could be used to connect to the fabric for fabric-attached hosts or could be used to connect directly to the Storage Management Server for in-band system management.
Support for iSCSI connection requires a minimum of XCS 5.1 or later and Command View EVA 5.x or later. N

23. Availability and serviceability
Managing HP Enterprise Virtual Array
Solution Overview
Several features promote availability and serviceability
I/O module with enhanced port bypass controller (E-PBC)
Allows easier resolution of drive problems
WEBES-SEA with Insight RSA or Insight RSS solution
Chosen tools for remote notification worldwide
Services only
Service port (serial line/Ethernet) for backend loop switches
Service ports for controllers or I/O modules
Customer self repair (CSR)
Instructions for removal and replacement are provided to the customer
EVA4400 is considered CSx (Customer Self Install, Customer Self Upgrade, and Customer Self Repair)
Instructor notes
Customers will not have a need for the Services-only access but this is nice-to-know information.
Regarding the I/O module with E-PBC:
E-PBC I/O module greatly enhances resolution of drive problems on the back end.
Full functionality is supported only by XCS firmware.
For EVA4400 model, the Environmental Monitoring Unit (EMU) functionality is built into the I/O module.
CSR reduces the need for HP field engineers to do simple repairs on binary failures.
There will be more in a later module on CSx.

24. Customer self repair (1 of 2)
Managing HP Enterprise Virtual Array
Solution Overview
CSR is an effort to improve product serviceability by allowing customers to perform hardware fault monitoring, diagnosis, and repair
Replacement part is sent to customer instead of using HP onsite service
All customer self repair (CSR) units purchased prior to February 2007 are optional (no charge for HP replacement) rather than mandatory (charge for HP travel/labor); as of February 2007, all EVAs sold have mandatory CSR
HP EVA warranty includes support for CSR
For EVAs with a warranty entitlement start date of 12 February 2007 or later, customers may ask HP Services to replace replaceable units (RUs) or perform a firmware upgrade of the disk drives for an additional charge
Customers who purchase an HP EVA support agreement have the option to perform CSR or receive on-site support
Instructor notes
CSR reflects the customers’ desire for self-sufficiency.
Over the last few years, research has clearly identified customer segments that want to participate in or perform a majority of the work involved in hardware fault monitoring, diagnosis, and repair. These findings were supported by a small survey of key North American EVA customers.
CSR components were supported on the first release of XCS (5.020) and the release of VCS
