Overview 3

http://www.ibm.com/software/passportadvantage

Required hardware

Each individual ESXi host machine must include the following hardwarecomponents:

v x86-64 CPU with 4 physical cores (without Hyper-Threading) dedicated for theSpectrum Accelerate virtual machine. 2 additional cores must be allocated for theESXi server functionality.

v At least 24 GB and up to 48 GB of RAM dedicated for the Spectrum Acceleratevirtual machine –– All ESXi host machines must have the same amount of physical RAM

dedicated for the Spectrum Accelerate virtual machine.– Additional and sufficient RAM must be allocated for the ESXi server

functionality.v 6 to 12 physical hard disk drives (HDDs) dedicated for the Spectrum Accelerate

virtual machine –– 1 TB or larger capacity (2, 3, or 4 TB) is required for each HDD. 6 TB disks

are not supported.– All HDDs must have the same capacity.– All ESXi host machines must have the same number of HDDs (6 to 12).– All HDDs must have up-to-date firmware. Check the HDD manufacturer

website to obtain the most updated firmware.

– An additional disk is required for the VMware ESXi Server software.– For better performance (not mandatory, but recommended) :

- Any RAID function of the disk controller should be disabled (all HDDsshould work in JBOD mode).

- Any SAS controller should function without a cache.v One solid-state drive (SSD) of 400 GB or larger capacity for caching purposes

(not mandatory, but recommended).v At least one 10-Gigabit Ethernet (10 GigE) port for the interconnect network; up

to eight ports per ESXi host machine.v At least one Gigabit Ethernet (1 GigE) port (or of higher capacity) for the

management and iSCSI networks.v Uninterruptible power supply (UPS).

Attention: Accidental power loss or improper system shutdown might result indata loss. In case of power loss, immediate manual shutdown of the storagesystem is required, followed by at least 30 seconds of continuous backup powerto allow graceful shutdown of the storage system.


Required ESXi configuration

Important: The ESXi platform must run on a 64-bit operating system.

Each individual ESXi host machine should be pre-configured with:

v No virtual machines (VMs) – Only a single VM is created for the SpectrumAccelerate virtual appliance after the deployment is complete.

v One datastore with at least 250 GB free space for storing the image of theSpectrum Accelerate virtual appliance.

v Management IP address for the Spectrum Accelerate virtual machine.v One or two IP addresses for iSCSI connectivity.v SSH access enabled (can be disabled after the deployment is completed).v SSH and ESX Shell services up and running.v Three separate IP subnets for the following Spectrum Accelerate networks:

– Management network– iSCSI network– Interconnect network

v NIC teaming configuration if more than one 10-Gigabit Ethernet port is used.

Required vSwitch, network, and deployment hostThe following table provides information about the required vSwitches,interconnect network, and deployment host.

Component Requirements

vSwitch One, two, or three vSwitches (virtual switches) withcorresponding port groups to which the management,interconnect, and iSCSI networks can connect.

As a best practice, the same port group names should bepredefined on all ESXi hosts on which you intend todeploy the IBM Spectrum Accelerate virtual appliance.

Interconnect network Must consist of a 10-Gigabit Ethernet LAN and mustinclude:

v One static IP address per module. All IP addresses mustreside in the same subnet.

v End-to-end MTU setting of 9000 bytes (Jumbo frame).

Note: Use of a private VLAN for the interconnect networkis recommended.

Overview 5

User responsibilitiesBecause IBM Spectrum Accelerate can be deployed on any commodity hardware ofchoice, users must furnish its hardware, set up and establish its interconnectnetwork, connect it to other networks as needed, deploy its software, andindependently monitor its server configuration and hardware components.

Users must also:v Maintain the ESXi server health, including the use of disk drives with up-to-date

firmware.v Verify that other virtual machines do not run in parallel to the Spectrum

Accelerate virtual machine on the same ESXi server, and that the ESXi server isnot used for any other purpose (other than hosting Spectrum Accelerate).

v Verify that the interconnect network is in good standing at all times.v Maintain the overall system operation environment, including the operating

temperature and continuous power supply for its servers, based on thespecifications of the hardware of choice.

v Regularly perform any required maintenance for disks and servers that comprisethe storage system.

v Perform the software upgrade procedure when needed.

ServiceabilityIBM Spectrum Accelerate requires customers to monitor their storage system andregularly provide any required physical service to disks, servers, and networks thatcomprise the storage system.

To allow IBM to provide proactive support for the Spectrum Accelerate storagesystems, the Enable Proactive Support option must be enabled and properlyconfigured in the management GUI per storage system.

For more information, see the IBM Spectrum Accelerate Planning, Deployment, andOperation Guide publication.

Known issuesThis section details the known issues in IBM Spectrum Accelerate, along withpossible solutions or workarounds (if available).

Important:

v When a newer version is released for general availability, the release notes ofversion 11.5.0.d will no longer be updated. Accordingly, check the release notesof the newer version to learn whether any newly discovered issues affect version11.5.0.d, or whether the newer version resolves any of the issues listed below.

Overview 9

Ticket ID SeverityAffectedversion(s) Description

SYS-252743 Medium 11.5.0.bor later

When entering several certificates to the certificate parameter,ipsec_connection_* CLI commands processes only the firstcertificate.

Workaround: Issue the relevant ipsec_connection_* commandfor one certificate at a time.

SYS-253004 Service 11.5.0.bor later

Resizing a pool (reducing its volume capacity) does not triggerthe STORAGE_POOL_VOLUME_USAGE_INCREASED event when crossingthe preset threshold.

Workaround: No workaround is currently available. Accordingly,use caution when resizing down a storage pool.


In some rare cases, the pki_set_pkcs12 CLI command might failwhen trying to set a certification.

Workaround: Issue the command again.


Deleting a user certificate reverts the system to the genericcertificate instead of to the unique system certificate.

Workaround: Set the system-unique certificate as a defaultbefore removing the user certificate.


Domain administrators from different domains that share aresource, can view and delete that resource's metadata.

Workaround: No workaround is currently available.


snmpwalk for volume statistics may take a long time whenmultiple volumes are defined.



When associating separate LDAP groups to separate domains, anLDAP directory user cannot belong to more than one group ifnot mentioned specifically by the group name in the format ofuser@domain1/domain2.

If a user is not defined in such a way and the memberOf fieldcontains more than one group, an LDAP_USER_CONFIG_ERROR eventis issued.



In IP filtering, FQDN host names are not supported byip_access_group_remove_address.

Workaround: Use an IP address instead.

SYS-265116 Low 11.5.0.bor later

When using the multi-tenancy feature, the system does not blockapplication administrators, who belong to user groups in theglobal domain, from being designated as IBM Hyper-ScaleManager users.

Workaround: Remove any application administrator from the listof IBM Hyper-Scale Manager users.




When working with IP filtering, a subnet cannot be added to anIP access group if an IPO, that is part of the subnet, alreadyexists in the access group.

Although the ip_access_group_add_address command is issuedwithout an error, the subnet is not added.


SYS-265489 Hyper 11.5.0.bor later

Spectrum Accelerate does not support using more than onetarget between two systems in a mirroring relation, as it mightcompromise the data on the destination. This operation,however, is not blocked by the system. It is blocked only whenusing the GUI in connected mode.

Workaround: A warning message is issued when trying todefine more than a single target. Keep in mind that there is nobenefit in defining more than a single target between twosystems, as one target is always enough.


If any of the parameters of pool_change_config are invalid, thecommand might start running and then fail halfway through.

Workaround: To avoid this problem, always runpool_change_config with valid parameter values.


IP filtering does not work for an IP range.

Workaround: Define an IP range by using an IP mask.

SYS-265764 Moderate 11.5.0.bor later

When changing a volume to read only, the system does notraise a SCSI Unit Attention to make the host aware of thechange.



When using IP filtering, there is no validation that a valid IPaddress is entered to the IP Access Group.



When adding IP addresses to an IP Access Group for IP filtering,two addresses cannot be added with the same IP, but withdifferent netmasks.


Overview 11



When using the default setting for an RHEL syslog server, whichdoes not implement Protocol-23 from RFC-5424(http://tools.ietf.org/html/rfc5424), most of the event data is notdisplayed.

Workaround: Modify default RHEL rsyslog configuration(/etc/syslog.conf).

Instead of the default:$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat

Use:$ActionFileDefaultTemplate RSYSLOG_SyslogProtocol23Format


The format=full parameter on the CLI help command is notsupported.

Workaround: Use -f all instead of format=full.


The ldap_user_list role=storageadmin CLI command does notlist domain administrators.



Using audit_config_set with a port number that is greater than65535 is not rejected. The default port number 514 is used.

Workaround: To avoid this problem, always use a legal portnumber that is smaller than or equal to 65535.


When using the muti-tenancy feature and LDAP authenticationmode, a domain with which users are currently associatedcannot be deleted.

Workaround: To resolve this problem:

1. Turn off the LDAP authentication.2. Dissociate the old users from the domain.3. Delete the domain.4. Turn on the LDAP authentication.

SYS-266620 Moderate 11.5.0.bor later

The multi-tenancy feature does not support Sun directory orOpen LDAP group objects. Static groups reflecting domainadministrators fail to log in, and receive an unrecognized rolecompletion code.

Workaround: Instead of the an LDAP group object attribute, usethe description string as hard-coded value per user. For moreinformation, refer to the IBM XIV Storage System Architecture andImplementation Redbook.


http://tools.ietf.org/html/rfc5424



Attempting to connect to an LDAP server over SSL might failand issue the LOGIN_FAILURE_LDAP_SERVER_UNREACHABLE errorafter a previous connection was made to LDAP without usingSSL, or connecting to an LDAP server with a different certificate.

Workaround: Always use a connection over SSL whenestablishing the connection for the first time. You can also try toestablish the connection from a different management port. Ifboth of these workarounds fail, contact IBM Support.


In the CLI help, the command descriptions for thedomain_manage and domain_move_gp commands are incorrect.

Workaround: Use the latest CLI reference guide.


IBM Hyper-Scale Manager supports LDAP UPN mode onlywhen there are no domains configured on the system. Ifdomains are configured on the system, LDAP UPN mode is notsupported.

Workaround: Try configuring the system using different LDAPlogin modes.


In some rare cases under extreme I/O rates, a single modulemight loose host connectivity.


SYS-269449 Low 11.5.0.c When working in LDAP mode integrated with multi-tenancy, theldap_user_list command returns Access Denied prompt whenissued by global administrators.


If defective hardware (disks, RAM, etc.) is encountered duringthe deployment, or if some required hardware components didnot initialize properly and in time with the rest of the system,the system might not start and then switch to Maintenance stateinstead.

Workaround:

1. Remove or replace the problematic hardware component.2. Perform the deployment procedure again.


During the deployment, FQDN host names in the format ofhostname.domain.com are required. If short host names are used(hostname part only), the deployment fails.

Workaround: Use a full FQDN name or IP address instead of ashort host name.

Overview 13



In some cases, the Spectrum Accelerate system might issue thefollowing error for some disks or disk controllers:

DISK_ERROR_SENSE_INFORMATION Disk xx:Disk:xx:xx had senseinformation indicating an error: xx/xx/xx (FRU=0000)ILLEGAL REQUEST - INVALID COMMAND OPERATION CODE.

This error can be ignored.



In some cases, a replaced disk might be erroneously detected asa previously used disk, and marked as Failed.

Workaround: This can be solved after occurrence by running thecomponent_test CLI command or Test GUI function for thespecific disk.


Incorrect Ethernet network speed is reported by both the GUIand CLI: 10 GbE is shown even if the actual speed is 1 GbE.



When collecting support logs, the following error might belogged:

DISK_ERROR_SENSE_INFORMATION Disk x:Disk:x:x had senseinformation indicating an error: xx/xx/xx (FRU=0000)ILLEGAL REQUEST - INVALID COMMAND OPERATION CODE

This error can be ignored.



The SSD cache drive might fail after upgrading the SpectrumAccelerate version.

Workaround: Issue the component_test and component_phaseincommands for the SSD drive after upgrade.
