Administrator Guide

Attribute Description
NOTE: Dell recommends that administrator account names not be reused after they have been
deleted. All accounts can always view their own audit log information, and new accounts with
previously used account names will be able to view audit records for the old account.
Password Password for the account can be 3 to 13 ASCII characters and is case-sensitive. Punctuation characters
are allowed, but spaces are not. Only the rst 8 characters are used; the rest are ignored (without a
message).
You are not required to provide passwords for Active Directory accounts and groups after Active Directory
has been congured. The passwords for these accounts are managed by the Active Directory server.
Description Optional description for the account. Descriptions can be up to 127 characters. Fewer characters are
accepted for this eld if you type the value as a Unicode character string, which takes up a variable
number of bytes, depending on the specic character.
Account type Can be one of group administrator, volume administrator, pool administrator, or a read-only account.
Pool access Pools to which the account has access and, if the account is a volume administrator, the storage quota
the account can manage within the selected pools. Applies to pool administrators and volume
administrators.
Additional access Grants the pool administrator read access to the entire group. Volume administrators have read access
only to the individual pools containing the storage quotas that they manage. In addition, you can grant
read-only users access to collect array diagnostics and/or save congurations.
Enable account Whether the account is active (enabled) or not. A user cannot log in to a disabled account.
Contact Information Name, email address, and phone numbers for the account owner. Contact name can be up to 63 bytes.
Email, Phone, and Mobile information can be up to 31 ASCII characters.
About Security Access Protocols
The PS Series group supports security protocols SSL/TLS and SSH, with a range of encryption algorithms. The protocols and
algorithms enabled by default include some older protocols (such as SSH v1 and SSL v2) and encryption algorithms that are no
longer recommended as best practices. The PS Series group supports SCP (secure copy) for copying rmware updates and
diagnostic les to and from the array. It is a secure alternative to FTP and Telnet. PS Series arrays also support IPSec protocols to
provide IPSec authentication and protection between group member arrays as well as between iSCSI initiators and the group. IPSec
protocols must be manually enabled using the CLI. IPSec can be enabled for a group only if all members of that group support IPSec.
For more information, see About IPsec.
Unless you need to enable access from older clients (web browsers or SSH clients) that do not support the current encryption
protocols and authentication algorithms, Dell recommends that you disable the legacy protocols and algorithms for best security.
You must use the CLI to disable the legacy protocols; see the grpparams crypto-legacy-protocols command in the Dell EqualLogic
Group Manager CLI Reference Guide. You can also enable or disable SSH v1 protocol support; see the grpparams cliaccess-ssh
command.
SSH Key Pair Authentication
SSH key pairs are two cryptographically secure keys that can be used to authenticate a client to an SSH server. Each key pair
consists of a public key and a private key. The private key is retained by the client and can be encrypted on disk with a passphrase
only. The associated public key can be used to encrypt messages that only the private key can decrypt.
Limitations
SSH key pair authentication supports the following:
• RSA and SSH 2 keys
• One public key per user
