2These components are packaged and sold as the T400 and T800 Storage Servers. They are exactly alike except the T800 is capable of twice the scaling of the T400. The F-Class is a cost reduced InServ Storage Server intended to complement the T-Class Servers in smaller deployments opportunities. The F-Class is 100% SW compatible with the T-Class and leverages the same InSpire Architecture for a single, load balanced system image. (same Management Console, same remote replication software, etc.).

As you can see, there is abundant and varied types of nodes, connectivity, drives, capacity, and performance. The point of all this is not win on spec-manship, but to provide a highly available and highly scalable single system that you can grow into, not out of, and they can be widely shared by many different applications. (Note on performancethese numbers are conservative results that can be achieved and sustained by any customer. No games. No specials.

Maximizes Throughput in MBs and IOPsServing Information17Speaker Notes :

Conducting your volume management using the 3PAR InForm OS is easy not just because is CENTRAL or ELIMINATES MANAGEMENT LAYERS, it is easy because it is AUTOMATIC. You dont have to know how to design a volume, or LUN, or RAID group, or drive layout to make a great volume for your applications. The 3PAR system does this for you intelligently, and automatically.

Wow, how can a system be that smart? Well, in addition to a lot of smarts in the SW, 3PAR relies on the idea of massive parallelism. Because a volume is ultimately broken into many many chunklets (very fine, only 256MB each), where the chunklets are disbursed across many drives (potentially all drives) in the system, even a very small volume taps the resources of the entire system! This leads to high performance, but more importantly, helps to ensure it once other volumes are added. Why? Because the chances of multiple volumes needing chunklets from the same drive at the same time (creating contention) are small. Need proof? See the next slide3PAR Company Confidential

3PAR RAID Multi Parity (MP) ConceptsRAID MP uses parity (double parity can deliver data in a double disk failure) to reconstruct data and performed in the ASIC XOR engine

RAID MP only supports two setsizes ( 8 and 16)

The default set size of 8 has the same data to parity ratio as the default RAID-5 set size of 4 -- 3:1 in both cases.

Working from the bottom up. 3PAR divides physical disks into 256MB chunklets.Logical disks which consist of one or more chunklets are mastered by one node and backed up by a second node. Virtual Volumes seen as LUNs by the host, are striped across nodes.

For example, if we create an 8GB LUN using createaldvv vvname 8g the 3PAR operating system will automatically give each node the responsibility of mastering all I/O. In the case above which has 4 nodes, the 8GB lun will be divided into 4x2GB Logical disks and each logical disk will have its I/O process by one primary node.

Each logical disks (2GB in this case) is striped across 256 MB chunklets. In this case 2GB logical disks is striped across 16 chunklets (each chunklet being on a separate physical disks). That is 2GB logical disks = 8 chunklets x 256MB (left-mirror-image) and 8 chunklets x 256MB (right-mirror-image)

As a result, the 8GB lun seen by the host in this example is striped across 64 physical drives on the back-end. That is, 4 nodes x 16 chunklets per node.3PAR Company Confidential

Serving Information613PAR Remote Copy

3PAR Remote Copy is a uniquely simple, efficient and flexible replication technology that allows customers to protect and share data of any application affordably. Implemented natively over IP and with a handful of simple, intuitive commands, 3PAR Remote Copy can be set up, managed, and tested in a matter of minutes. Costly and prolonged professional services engagements, common with other replication technologies, are eliminated. Special extenders or converters that permit long distance replication are also eliminated. With Remote Copy users may flexibly choose to use one or both modes of operation: asynchronous periodic and synchronous (which supports native Fibre Channel connectivity as well). Remote Copy allows users to mirror data between InServ Storage Servers of any model and configuration, eliminating the incompatibilities and complexities associated with trying to mirror between traditional vendors' midrange and highend array technologies. Source and target volumes may also be flexibly and differently configured to meet users needs (e.g., different RAID levels and drives types). Special efficiencies stem from the "thin copy" capabilities of Remote Copy. Since Remote Copy is Thin Provisioning-aware, target volumes provide the same dramatic cost savings and ease-of-use benefits associated with thin provisioned source volumes. Bandwidth is also efficiently utilized since (with asynchronous periodic mode) changed data within a volume or consistency group is transferred only once -- no matter how many times it may have changed between synchronization intervals.

Note: Remote Copy enables Thin Copy Reclamation for online thin copy rethinning an industry first! Capacity can be freed from Thin Copies (Full/Virtual/Remote Copies) as they age and are deleted. There is minimal performance overhead.

ReadyInstant readable or writeable snapshotsSnapshots of snapshots"mySnapshot utilityVirtual Lock for retention of read-only snapsbut justone CoW66Another big area in which 3PAR provides large efficiency gains is in the area of copied and replicated data. 3PAR Virtual Copy is a uniquely simple, efficient and scalable copy-on-write snapshot technology that allows customers to protect and share data from any application affordably. Snapshots are available on demand, instantly, in read-only and/or read-write form. Snapshots are also reservationless, with chunklets consumed only for changed data. Additional efficiency comes from a table-based implementation whereby changed data is never duplicated within a snapshot tree. Coupled with the ability to take hundreds of snapshots per base volume, this efficiency delivers (CDP-like) rapid application recovery affordably from multiple points in time. 3PAR customer routinely take hourly snapshots and retain them for extended periods, given them a cost-effective library of recovery points.

Virtual Copy enables Thin Copy Reclamation for online thin copy rethinning an industrys first! Capacity can be freed from Thin Copies (Full/Virtual/Remote Copies) as they age and are deleted. There is minimal performance overhead. Supported on all InServs (T, S, F and E-class)

Customers may also take snapshots of snapshots for fast, flexible sharing of data sets without the need for additional base volumes. With a single command, a base volume may be reverted to any selected snapshot at any time, without affecting other snapshots in the tree. Similarly, snapshots may be deleted from a tree without affecting peer snapshots. 3PAR Virtual Copy supports consistency groups for data integrity across volumes.

Virtual Copy is integrated with a number Recovery Manager offerings from 3PAR that allow discovery of and consistent snap-shotting with Oracle, Exchange, and SQL.

What is MySnapshot?===============The unmount and remount onthe host are not done by updatevv (it can only make changes on the InServ). Those are the responsibility of the user.

a. (unmount disk on host OS) - user does thisb. updatevv vvnamec. (remount disk on host OS) - user does this.

What updatevv does (assuming VV is a rw snap and -ro is not specified):1) remembers the VLUNs for the VV2) removes the VLUNs3) remove VV (rw snapshot)4) creates a new rw snapshot of the parent using the same name as the VV, and if possible, the same id5) recreates the same VLUN

If -ro is specified, it also removes and recreates the ro parent

Note that some OSs cache stuff about the VV so it is a pain to do the equivalent of unmount/mount.

Why Host PersonasDifferent operating systems require slightly different behaviors both from the port level and the SCSI layer

Host persona splits this into SCSI layer behaviors (host persona capabilities) and port behavior settings (via controlport config)

Multiple host types can share a single InServ StorageServer port.

Each host initiator gets its unique FC/SCSI level behavior.Serving Information___________________________________________________________
