Lenovo Storage S3200 with Fibre Channel

Introduction

Reference designs have become an essential part of many customer data centers

allowing for rapid deployment of a system that has been tested and assured to work by a

vendor. They ensure that all of the components work together and can give someone

who is unfamiliar with some aspects of the deployment a starting place to go for

answers. Further, they enable an understanding of where a set of hardware fits into a

data center and allows for a simpler decision process. Why would you evaluate a

solution that does not fit your needs?

This document specifically discusses an infrastructure design using Lenovo Fibre

Channel networking from Brocade, Lenovo servers, Lenovo storage, and Emulex Fibre

Channel Host Bus Adapters (HBAs) by Broadcom. Users who may be using NAS or

iSCSI today and are considering an entry Fibre Channel solution will find the information

contained within this document useful to create a basic configuration.

Once you have completed reading this document, you will understand how to zone a

Fibre Channel switch and how to make LUNs available to your chosen OS for file

storage or OS deployment. It covers all basic steps up until the installation of the

operating system. The document also includes a sizing guide to help understand what

equipment will work best in a given environment.

This design document includes technology and input from three of the leading vendors in

IT today: Lenovo, Emulex (a division of Broadcom Limited), and Brocade. These three

partners have a complimentary portfolio that allows for innovation in an individual and

specialized area while collaborating and providing best of IT solutions. All three vendors

have priorities set for achieving performance that is best in the industry and reducing

deployment times by minimizing administrative complexity.

Use Cases

Primarily, the reader of this document will be an administrator or user who desires an

assurance that a design is valid and that all parts have been tested together. This is a

high-level design that may fulfill a purpose perfectly by changing the processor, memory,

or the amount of storage. Details on creating a configuration are in the sizing section of

this document.

The use cases that we have targeted with this design include:

 Media streaming

 Web hosting

 OLTP databases

 Hosting communications (IM, email, shared storage)

 Private cloud and general usage

Solution Overview

This design is flexible to accommodate differences in environments and computing

requirements. We made optimal selections from the broader product portfolios to ensure

that the target design considers cost, performance, and capacity. The principals

discussed within this document can allow for a small deployment as the primary use

case but can work for a medium sized deployment or even a large deployment when

using pod design philosophies.

Lenovo Storage S3200

Lenovo Storage S3200 with Fibre Channel

The Lenovo Storage S3200 can contain as many as 192 drives ranging from NL SAS to

SSDs depending on performance and storage capacity needs. The S3200 also offers

Intelligent Real-Time Tiering that can optimize storage performance, reduce cost, and

simplify management. Features also include SSD read cache, virtualized storage pools,

snapshots, and thin provisioning. With 6.4 GBps maximum sequential read throughput

and 5.3 GBps maximum sequential write throughput at a 512KB block size, the Lenovo

Storage S3200 can handle most workloads with a single dual-controller enclosure at an

affordable price.

Thin Provisioning

In supported operating systems (recent versions of Linux, VMWare, and Windows), thin

provisioning can create a very large volume that only uses the space on disk that is

required while leaving the other disk space for other volumes. This allows you to have a

setup that can expand and grow over time as needed and allows for several scenarios

that can save time and money.

 Allows for provisioning a larger volume than should be needed to accommodate

any future growth that is unexpected

 Fewer drives may be purchased initially with the plan for buying more as needed

o Drive prices reduce over time and the size of drives continues to

increase, meaning in 2 years you can purchase a larger drive for less

money

 No more estimating what an application will need for storage

o A larger value can be used and if an application doesn't use it, no space

is wasted

We tested thin provisioning on the storage array for this validation.

Lenovo Storage S3200 with Fibre Channel

Single Copy on Write (SCW) Snapshots

The Lenovo Storage S3200 uses a snapshot technology called single copy on write

(SCW) with Original/Write Data Preservation capabilities. This technology reduces the

size of snapshots by preserving the data captured in a snapshot in place and then

writing to a new snapshot volume for all writes going forward. This significantly improves

speed of writes compared to methods such as copy on first write (COFW).

These snapshots allow rollbacks in the case of administrator error or a malicious user

overwriting information. Ransomware can be removed completely without a headache or

dealing with a criminal. It can also be very useful in a development environment to

create a point in time to roll back to after performing some actions to test a new

configuration and then to roll back in minutes to an old configuration.

We validated snapshots on the Lenovo Storage S3200 as part of this project.

Virtualized Storage Pools

Virtualized storage pools allow for flexible creation of storage volumes by writing

sections of data to different media types. When combined with Intelligent Real-time

Tiering, this allows data to be written to faster media when it is being accessed often and

to be stored on slower media when it is being accessed less frequently. In addition to

enabling performance gains, the virtualized storage pools simplify the management of

storage volumes. More storage can be added to the volumes via these storage pools

without requiring a full rebuild of a volume which saves time, money, and ensures data

integrity.

We used storage pools during this validation.

Lenovo Storage S3200 with Fibre Channel

SSD Read Cache and Tiering

Tiering occurs on the Lenovo Storage S3200 by separating drives into three types:

 Archive – 7200 RPM drives

 Standard – 10K or more RPM drives

 Performances – SSDs (requires optional license)

Automatic tiering occurs among the different pools of drive types based on the frequency

of data access. Data blocks associated with frequently accessed files will migrate to the

highest performance tier available, while rarely accessed data blocks will be migrated to

a higher capacity tier. This process allows for users or applications to change their

access patterns and have the storage optimize itself every 5 seconds without any

administrator prevention.

The SSD read cache is another option for improving performance by expanding the

effective size of the controller cache without any additional licensing costs. Both

performance tiering and the SSD read cache were tested as part of this validation. The

tiering occurred at a granular level in 4MB chunks that allowed frequently accessed data

to be determined in a programmatic way without any user intervention. It is easy to

monitor where data is stored on the S3200 via either the command line or the GUI.

Lenovo Storage S3200 with Fibre Channel

Lenovo B300

The Lenovo B300 Fibre Channel Switch has up to 24 ports (8 ports licensed by default;

the remaining ports can be licensed in 8-port increments). The switch offers a rich set of

standard software features with the options to expand its capabilities as needed.

The B300 features the EZSwitchSetup wizard and can be configured in Access Gateway

Mode to simplify deployment. The switch provides full non-blocking performance with

Ports On Demand scalability to support SAN expansion and enable long-term

investment protection.

Lenovo B6505/B6510

The Lenovo B6505 Fibre Channel Switch can be configured as 12 or 24 ports while the

Lenovo B6510 Fibre Channel Switch can be configured as 24, 36, or 48 ports. Every

port in these configurations is non-blocking with a port-to-port latency of 700 ns while

running at 16 Gbps. This gives these specialized storage ports industry-leading, real

world benchmark numbers at scale. Beyond bandwidth and latency, these switches offer

manageability and ease of use through their multiple methods of setup including a CLI

and GUI with policy based alerting as an option to ensure that there are no outages for

critical data paths.

With support for Brocade's Fabric Vision™ technology both the B6505 and B6510 have

deep visibility into what is occurring on the storage fabric. An administrator can validate

physical components to ensure that no component is borderline or failing. This prevents

a cable from having a bend radius issue and degrading the performance of a whole

fabric over an important link. Additionally, beyond an initial validation, the administrator

can be alerted once policies have exceeded their limits and know about a problem

before users and their applications see the failures.

With industry leading performance, simplified setup, and easy debugging and

troubleshooting, what more could be asked from a storage network?

Lenovo System x3550 M5

Leading the industry in reliability, Lenovo's most recent server offerings achieve

99.999% availability that equates to an average of 6.05 seconds of server downtime per

week. This reliability drastically reduces costs for both Lenovo and its customers,

allowing Lenovo to deliver cost efficient solutions at a lower price point.

The Lenovo System x3550 M5 is a 1U two-socket rack server that utilizes Intel Xeon E5-

2600 v4 processors, up to 1.5 TB of TruDDR4 Memory, and up to 12 drive bays to

deliver energy and space efficiency that matches or beats the best in the industry. The

server is designed for energy efficiency, including power supplies that deliver 80 PLUS

Titanium performance ratings. 80 PLUS Titanium is the highest achievable 80 PLUS

rating, which enables infrastructure, including breakers and UPS units, to be correctly

sized. They also save money over time by using less power.

The server also includes built-in reliability, such as Predictive Failure Analysis

and light path diagnostics to proactively monitor the server components and

identify failing parts. Lenovo servers ranked #1 in reliability for the third year in a

row, according to an independent ITIC 2015-2016 survey.

The Lenovo System x3550 M5 rack serverdelivers enterprise-class performance,

reliability, and efficiency at a competitive price.. .

transactions over 8GFC HBAs. They are ready for NVMe over Fibre Channel, which

accelerates network access to SSDs, supporting the upcoming NVMe over Fibre

Channel T-11 standard.

All Emulex adapters allow you to deploy faster and mange less with a unified

management tool (OneCommand® Manager) and common driver set.

Sizing Information

Server Sizing

Sizing a virtualized solution has numerous complexities for optimization that can be

taken into consideration for a completely optimal deployment. Numerous technologies

are on the market that can make this job significantly easier. VMWare® Distributed

Resources Scheduler (DRS) is the software product that enables VMWare to assist in

moving virtual machines to optimal locations in a cluster. With DRS, you can select to

allow migration to happen automatically or to merely monitor and suggest changes that

the administrator can allow or disallow. This feature is available in VMWare® Enterprise

and Enterprise Plus and simplifies both the initial sizing and understanding what

compute resources may be required going forward.

When a cluster is running DRS, server sizing requires a few simple yet complicated

questions:

 What is the CPU capacity required for my applications?

 How much RAM is needed for my applications?

 Is there a requirement for a large amount of network or storage I/O?

If the current environment is not setup for virtualization yet, there are tools on both

Windows and Linux that can help with the sizing. Standard Linux tools such as sar, ps,

mpstat, top, and free can give a very strong idea on what may be required of a system's

virtualized equivalent when compared to the hardware that is inside a server. Windows®

has similar commands that can help with this transition such as PerfMon that will give

detailed information about how all systems are functioning. If already running VMWare®

vSphere on the cluster, esxtop is a good choice in gathering this information to help in

sizing.

Once this information has been gathered, it should be compiled together. Approximately

20% headroom for future growth or burst usage should be left as available. For RAM

Lenovo Storage S3200 with Fibre Channel

utilization, it is a simple matter of adding up memory usage across the servers and then

adding some overhead. For CPU utilization, it is most likely simplest to follow some

steps such as the below to determine what should be purchased:

 Current CPU core GHz and quantity

 Current utilization percent averaged across servers to be virtualized

 Multiply current average utilization by quantity and GHz or current cores

o For ease of calculation, let’s assume we measured a 20% peak utilization

o Separate calculations for different server types or workloads may be done

and then added together

o 112 cores * 2.4GHz * .20 for utilization = 53.76GHz required

 Multiply proposed CPU core GHz by core quantity in server for server total

o 3.0GHz * 20 cores (across 2 CPUs) = 60GHz

 Multiply previous value on current setup by 1.20 for overhead and then divide by

servers

o 53.76GHz * 1.20 = 64.512GHz

o 64.512GHz / 60GHz per server = 2 servers required to safely run required

workload

To prepare for the event of a failure, an additional server should be available in an HA

cluster. It could be assumed that the second server in most scenarios with the above

calculation would be fine, so it is up to the discretion of the administrator familiar with the

workloads as to what his requirements are.

Network Sizing

Network sizing generally is very simple when utilizing a 10 Gbps network as it is unlikely

that that amount of bandwidth will be exceeded and even more unlikely when using the

commonly suggested method of bonding two adapter ports together to a form a 20 Gbps

trunk. If network usage is a concern, PerfMon on Windows and tools such as ntop or

cacti may be deployed on Linux.

Storage Sizing

There are two primary considerations when sizing storage in both a bare metal and a

virtualized environment. The most obvious consideration is storage capacity that has

several features related to it that can save a lot of money when purchasing drives. The

second consideration is the performance of the storage that can be the latency to reach

Lenovo Storage S3200 with Fibre Channel

that storage, IOPS, or throughput. Differences between IOPS and throughput can be a

consideration if the size of each transfer per IO is very small or very large. For this

exercise, we will assume 512KB blocks. Numbers will need to be adjusted accordingly if

your block size varies from this.

Storage Capacity Planning

When using thin provisioning as provided through the Lenovo Storage S3200 or

VMWare® VMDK thin provisioning, virtual storage pools should be used on the S3200.

Thin provisioning allows for new capacity on demand and has many feature

enhancements that make it the preferred option. With thin provisioning, storage usage

can grow over time as operating systems and the applications running on them grow

databases and logs.

For the initial purchase and requirements of a deployment, each guest hosted in a virtual

machine will be very different based on the sizing requirements of each operating

system and application. A few rules of thumb can help us know a good starting point and

can help us move forward to next steps until we can revisit specific numbers.

 A typical full Windows® Server 2012 installation requires approximately 32

gigabytes for the operating system itself without deduplication, depending on the

version of Windows®

 Each full Linux installation generally requires approximately 4 gigabytes for the

operating system itself without deduplication, depending on the distribution and

the options selected at install time (newer distributions may use 20GB or more)

 Applications will give guidance on their specific storage requirements

The calculations are as simple as the OS install size combined with the application

install size requirements along with a small amount of overhead. For example, sizing a

web server running Nginx™ for storage would be done like the below:

 Operating system install for CentOS® 7 requires 20GB

 Nginx™ is included as part of the 20GB

 Configurations or files to be executed and served will be a trivial amount extra

 20% overhead would be 4GB

 Provision more than 24GB for a simple Nginx™ web server or load balancing

setup on CentOS® 7

o Thin provisioning means we should expect 24GB to be used, but we can

create a larger volume

Lenovo Storage S3200 with Fibre Channel

Storage Performance Planning

Storage performance is an often overlooked aspect of planning an array. It is very

common either to provide too little performance for applications or to provide too much.

Applications will suffer with too little while budgets will suffer with too much. Performance

planning is simplified with hybrid arrays such as the Lenovo Storage S3200. Tools such

as iostat on Linux or PerfMon on Windows will allow you to view your applications

required IOPS. If using vSphere, you can use the performance charts to get a good idea

on what the storage performance requirements will be.

Sizing with an S3200 is made easier by having either an SSD read cache or

performance tiering to SSDs. These features allow the usage of high performance SSD

drives that will allow for thousands of IOPs per drive.

Lenovo B300, B6505 and B6510 considerations

The B300 is an entry level switch for small storage networks. For customers doing

deployments that use 18 or fewer servers and have no upstream SAN, the Lenovo

B6505 with its lower cost of acquisition, will be an optimal fit. If a customer has an

existing SAN, more than 18 servers, or plans on deploying multiple iterations (pods) of

the design detailed in this document, they should use a Lenovo B6510.

With the non-blocking nature of these Generation 5 (16Gbps) Fibre Channel switches, a

single switch configuration requires the consideration of how much bandwidth needs to

go to a compute node as well as the uplinks to storage. With 16 Gbps speeds, two links

to each controller on the S3200 should saturate the system and the same will occur on

the server. For multiple switch configurations, see the Brocade SAN Design and Best

Practices Guide in the Other Reading section.

Validation Setup and Diagram

The validation setup included three servers, two Fibre Channel switches, and one

storage array with a minimum configuration of drives. These drives consisted of four

nearline SAS drives and two SSDs for a performance tier. The performance tier license

was applied. Also included was 10 gigabit and gigabit Ethernet infrastructure for

management and node communication that is not included in this document. For

reference, a Brocade ICX 6430 and two VDX 6740 switches were utilized. For details on

what was tested, see the Bill of Materials section below. For a visual representation of

the storage configuration, see the figure below.

Lenovo Storage S3200 with Fibre Channel

Configuration Hints

Brocade

Three basic things must be done in any Fibre Channel configuration. There are

advanced steps including monitoring, optimization, and ensuring reporting of any errors

that are discussed in other documents. The three primary steps are:

 Set an IP address

 Update firmware

 Configure zoning

Serial Port Setup

Lenovo Storage S3200 with Fibre Channel

The first step to configuring any of these settings is to connect via the serial console.

There is an included serial cable with the switch. This serial cable can be connected to

an adapter on a laptop or another server. A popular serial terminal program is PuTTY,

which can be downloaded from the web, and there is a link in other reading. Screen is a

favorite Linux serial emulator of many administrators and can be used. The serial

settings in PuTTY only require changing the COM port to match what your adapter is set

to. To learn what COM port, navigate to the Device Manager that can be accessed via

running the command mmc devmgmt.msc or navigating through standard menus.

Logging In, Setting the IP Address and Updating Firmware

Once you have accessed the switch's serial console, you can login with the default

password for the account. If you are planning to script any zoning, log in as root with the

password “fibranne” by default. If you will be doing manual zoning or zoning through the

WebTools interface, you can login as admin with the password “password” by default.

These passwords should be changed, which can be done on the command line with the

passwd command. The syntax is simply passwd admin and then following prompts.

Lenovo Storage S3200 with Fibre Channel

Both the commands we need for the next steps can be menu driven. There is a

verification step in between we can run to ensure that our settings are correct. The

commands we want to run are in the list below.

 Ipaddrset

 ping $IPADDRESS

 firmwaredownload

o As a note, firmwaredownload is optional and for most environments may

not be required

Answer the menu driven prompts and you will have a switch that is ready to be

managed.

Zoning

The below are command examples for setting up a simple zoning configuration:

 alicreate "Example_Alias_1", "xx:xx:xx:xx:xx:xx:xx:xx"

 zonecreate "zone_Example_1", "Example_Alias_1; Stor_Example_Alias_1;

Stor_Example_Alias_2"

 cfgcreate "lenovo","zone_Example_1; zone_Example_2; zone_Example_3"

 cfgsave

 cfgenable "lenovo”

Lenovo Storage S3200

By default, the S3200 has a static IP address configured which will be active unless

there is a DHCP assignment given to it. The default IP addresses are 10.0.0.2 and

10.0.0.3 with a /24 CIDR (255.255.255.0 netmask.) In an environment that has DHCP,

you can learn the IP assignment by checking the system logs or you can simply directly

attach an Ethernet cable to a server or laptop with an address assigned to the interface

such as 10.0.0.4 with a 255.255.255.0 netmask.

Once you can establish connectivity, there are two primary options of setting up the

storage. The option displayed in this guide is the web interface, but the CLI can achieve

the same result. See the Other Reading section for additional documentation including

the CLI reference guide.

Lenovo Storage S3200 with Fibre Channel

The first page to greet you will appear as the below. Note that approved optics must be

used in the ports. Otherwise, they will be disabled as is shown in the image.

The first step in configuring your array is to set up disk groups. You can divide these

groups up later to individual nodes via the creation of volumes and you should combine

drives into pools. There are performance considerations for assigning a large number of

drives into a single disk group and having every node in a single pool where the IO

blender (multiple servers at once accessing the same resource) can lead to significant

random reads and writes. Because of this, size the pools appropriately and keep in mind

additional disk groups can be added in the future. It also should be noted that having

pools on the separate controllers would ensure load balancing. Because of this, having

at least an A and a B pool is considered best practice.

Lenovo Storage S3200 with Fibre Channel

Additional disk groups can be added to a single pool. In the case of performance tiering,

ensure that it is added to the same pool as the other disk groups.

Once your disk groups are created and assigned to their pools, volumes should be

created. You can create multiple copies of a single volume sizing and select which pool

to draw from. In our case, we created three to be used on our three servers.

Lenovo Storage S3200 with Fibre Channel

The final step to a basic storage setup is to map the volumes to the hosts. Select the IDs

that are sequential and map them to the correct volumes. You can verify that the WWNs

displayed in the ID field are unique by checking on the host.
